Encryption tab

Using this tab, you can:

• Monitor the encryption key rotation status
• See the list of Citrix Provisioning servers that are waiting on key distribution
• Rotate the encryption key

Key rotation distributes a new database encryption key to all the Citrix Provisioning servers in the farm. After the distribution is complete, the database is re-encrypted with this new key. This process ensures enhanced database security.

The description of the states of the encryption are as follows:

Distributing Keys: This is the first state of key rotation. In this state, the new database encryption key is being synchronized with all the Citrix Provisioning servers. The farm remains in the Distributing Keys state until all the servers have the latest encryption key. To retrieve the new encryption key, a Citrix Provisioning server:

• must be active (that is, must not be offline) until it gets the new encryption key. You can turn off the server once it gets the new encryption key.

Re-encrypting Database: This is the next state after Distributing Keys. In this state, after all the Citrix Provisioning servers in the farm get the new encryption key, the encrypted fields in the database are re-encrypted with this new encryption key.

Idle: This is the next state after re-encrypting the database. This state implies that the key rotation process is complete. The Rotate Encryption Key button is enabled when the encryption status is Idle. After you click Rotate Encryption Key, the state changes to Distributing Keys.

Note:

• Each encryption key cycling job takes a minimum of 5 to 10 minutes to move to the next state. However, the process is delayed if there are offline Citrix Provisioning servers.
• You might see a Citrix Provisioning server that initiated the key rotation in the list of servers that are waiting on key distribution even after the server in the farm gets the new encryption key immediately. Wait for approximately 5 minutes for that server to finish its key rotation process, after which it moves out of the list.
• You cannot add new Citrix Provisioning servers in the farm when the state is Distributing Keys or Re-encrypting Database.
• If you create a new farm using the Configuration Wizard, wait for the state to change to Idle and only then add new Citrix Provisioning servers to the farm.
• To add a Citrix Provisioning server to an existing farm, ensure that at least one server that has the encryption key is active (that is, must not be offline) so that the new server gets the encryption key. If no server is online, the new server fails to get added to the farm. In that case, ensure at least one server is active, and then rerun the Configuration Wizard on the new server that you want to add.
• Do not delete the Provisioning Services keys from the registry. If they get deleted, there must be at least one Citrix Provisioning Server in the farm that has the encryption data with which the database and registry fields were encrypted. We recommend taking registry backups including the HKLM\Software\Citrix\ProvisioningServices registry key.

Using PowerShell and MCLI commands to rotate encryption key

You can now use PowerShell and MCLI commands to rotate encryption keys. Before using the commands, make sure that encryption status is Idle.

Using PvsPsSnapIn:

1. Open the PowerShell window.
2. Install the PowerShell Snap-In. The path where the Citrix.PVS.SnapIn.dll is installed is: C:\Program Files\Citrix\Provisioning Services Console\Citrix.PVS.SnapIn.dll

3. Run Start-PvsRotateEncryptionKeys to start the key rotation process. After you run the command, the key rotation status changes to Distributing Keys.

   Note:

   If you run the command Start-PvsRotateEncryptionKeys when the key rotation status is Distributing Keys or Re-encrypting Database, you get an error because the key rotation is in process and keys can be rotated only when the key rotation status is Idle.

4. Run Get-PvsKeyRotationPendingServers command to get the list of servers in the farm that are waiting on key distribution and servers that are offline.

   Note:

   • When the key rotation status is:
     • Distributing Keys, you get the list of servers that are waiting on key distribution.
     • Re-encrypting Database or Idle, you get the list of servers that are offline.
   • You might see a Citrix Provisioning server that initiated the key rotation in the list of servers that are waiting on key distribution even after the server in the farm gets the new encryption key immediately. Wait for approximately 5 minutes for that server to finish its key rotation process, after which it moves out of the list.

5. Turn on any server that is offline. Ensure that the servers in the farm can communicate with each other.

6. After the key rotation process is complete, the status of the key rotation must change to Idle. Run the command Get-PvsFarm to verify the key rotation status. The values of the property EncryptionStatus:

   • 0: Idle state
   • 1: Distributing Keys
   • 2: Re-encrypting Database

Note:

Each encryption key cycling job takes a minimum of 5 to 10 minutes to move to the next status. However, the process is delayed if there are offline Citrix Provisioning servers and servers waiting on key distribution.

Using MCLI.exe:

1. Open the PowerShell window.

2. Run .\MCLI.exe Run CycleEncryptionKeys to start the key rotation process. After you run the command, the key rotation status changes to Distributing Keys.

   Note:

   If you run the command .\MCLI.exe Run CycleEncryptionKeys when the key rotation status is Distributing Keys or Re-encrypting Database, you get an error because the key rotation is in process and keys can be rotated only when the key rotation status is Idle.

3. Run .\MCLI.exe Get PendingServers command to get the list of servers in the farm that are waiting on key distribution and servers that are offline.

   Note:

   • When the key rotation status is:
     • Distributing Keys, you get the list of servers that are waiting on key distribution.
     • Re-encrypting Database or Idle, you get the list of servers that are offline.
   • You might see a Citrix Provisioning server that initiated the key rotation in the list of servers that are waiting on key distribution even after the server in the farm gets the new encryption key immediately. Wait for approximately 5 minutes for that server to finish its key rotation process, after which it moves out of the list.

4. Turn on any server that is offline. Ensure that the servers in the farm can communicate with each other.

5. After the key rotation process is complete, the status of the key rotation must change to Idle. Run the command .\MCLI.exe Get Farm -f to verify the key rotation status. The values of the property EncryptionStatus:

   • 0: Idle state
   • 1: Distributing Keys
   • 2: Re-encrypting Database

Note:

Each encryption key cycling job takes a minimum of 5 to 10 minutes to move to the next status. However, the process is delayed if there are offline Citrix Provisioning servers and servers waiting on key distribution.

Using McliPsSnapIn:

1. Open the PowerShell window.
2. Install the PowerShell Snap-In. The path where the Citrix.PVS.SnapIn.dll is installed is: Import-Module "C:\Program Files\Citrix\Provisioning Services Console\McliPSSnapIn.dll"

3. Run Mcli-Run CycleEncryptionKeys to start the key rotation process. After you run the command, the key rotation status changes to Distributing Keys.

   Note:

   If you run the command Mcli-Run CycleEncryptionKeys when the key rotation status is Distributing Keys or Re-encrypting Database, you get an error because the key rotation is in process and keys can be rotated only when the key rotation status is Idle.

4. Run Mcli-Get PendingServers to get the list of servers in the farm that are waiting on key distribution and servers that are offline.

   Note:

   • When the key rotation status is:
     • Distributing Keys, you get the list of servers that are waiting on key distribution.
     • Re-encrypting Database or Idle, you get the list of servers that are offline.
   • You might see a Citrix Provisioning server that initiated the key rotation in the list of servers that are waiting on key distribution even after the server in the farm gets the new encryption key immediately. Wait for approximately 5 minutes for that server to finish its key rotation process, after which it moves out of the list.

5. Turn on any server that is offline. Ensure that the servers in the farm can communicate with each other.

6. After the key rotation process is complete, the status of the key rotation must change to Idle. Run the command Mcli-Get Farm to verify the key rotation status. The values of the property EncryptionStatus:

   • 0: Idle state
   • 1: Distributing Keys
   • 2: Re-encrypting Database

Note:

Each encryption key cycling job takes a minimum of 5 to 10 minutes to move to the next status. However, the process is delayed if there are offline Citrix Provisioning servers and servers waiting on key distribution.

        • New Site: Create a site by typing the name of the new site and a collection.
     5. Continue on to configure the user account settings.

Identify the database

Only one database exists within a farm. To identify the database:

1. If the database server location and instance have not yet been selected, complete the following procedure.

   1. On the Database Server dialog, click Browse to open the SQL Servers dialog.
   2. From the list of SQL Servers, select the name of the server where this database exists. Specify the instance to use (to use the default instance, SQLEXPRESS, leave the instance name blank). In a test environment, this configuration can be a staged database. Note: Rerunning the Configuration Wizard to add extra provisioning server database entries, populates the Server Name and Instance Name text boxes. By default, SQL Server Express installs as an instance named SQLEXPRESS.
   3. Select Active Directory Integrated authentication if you want to use the services’ user account. Enter the database credentials that the Stream and SOAP services will use.
   4. Click Next. If this database is a new farm, continue on to the Defining a Farm procedure.

2. To change the database to a new database

   1. On the old database server, perform a backup of the database to a file.
   2. On the new database server, restore the database from the backup file.
   3. Run the Configuration Wizard on each Citrix Provisioning server.
   4. Select Join existing farm on the Farm Configuration dialog.
   5. Enter the new database server and instance on the Database Server dialog.
   6. Select Active Directory Integrated authentication if you want to use the services’ user account. Enter the database credentials that the Stream and SOAP services will use.
   7. Select the restored database on the Existing Farm dialog.
   8. Select the site that the provisioning server was previously a member of on the Site dialog.
   9. Click Next until the Configuration Wizard finishes.

3. Define a farm. Select the security group to use:

   • Use Active Directory groups for security Note: When selecting the Active Directory group to act as the farm administrator from the menu, choices include any group the current user belongs to. This list includes Built in groups, which are local to the current machine. Avoid using these groups as administrators, except for test environments. Some group names might be misleading and appear to be domain groups, but are local domain groups. For example, ForestA.local/Builtin/Administrators.
   • Use Windows groups for security

4. Click Next.

   Continue on to select the license server.

Create a store for a new farm

A new store can be created and assigned to the Citrix Provisioning server being configured:

Note: The Configuration Wizard only allows a server to create or join an existing store if it is new to the database. If a server exists in the database and it rejoins a farm, the Configuration Wizard might prompt the user to join a store or create a store. During this process, the selection is ignored.

1. On the New Store page, name the new Store.
2. Browse or enter the default path (for example: C:\PVSStore) to use to access this store, then click Next. If an invalid path is selected, an error message appears. Reenter a valid path, then continue. The default write cache location for the store is located under the store path for example: C:\PVSStore\WriteCache.

Identify the site

When joining an existing farm, identify the site where this provisioning server is a member. Identify a site by either creating a site or selecting an existing site within the farm. When a site is created, a default target device collection is automatically created for that site.

Join Citrix Cloud or Citrix Virtual Apps and Desktops site

Using the Join Citrix Cloud or CVAD page, you can choose to join your farm with Citrix Cloud, a Citrix Virtual Apps and Desktops site, or choose to not join your farm.

Important:

• The Join Citrix Cloud or CVAD page appears only when the farm is NOT joined. If you select to join the farm to Citrix Cloud or Citrix Virtual Apps and Desktops site, you do not see this page again.
• If you want to revert to a non-cloud joined or non-Citrix Virtual Apps and Desktops site joined farm, you must recreate the farm.

If you choose to join your farm with Citrix Cloud, then you can additionally:

• Provision Citrix Provisioning targets using the DaaS Web Studio (Full Configuration interface).

If you choose to join your farm to a Citrix Virtual Apps and Desktops site, then you can additionally:

• Provision Citrix Provisioning targets using the Citrix Virtual Apps and Desktops Web Studio.

Note:

• For successfully joining your farm to a Citrix Virtual Apps and Desktops site, when running the Configuration Wizard, use a Windows login that has Machine Catalog Administrator or higher privileges in Citrix Virtual Apps and Desktops.
• If you want to join your farm to a Citrix Virtual Apps and Desktops site, you must provision an SSL server certificate on all the servers in the farm. You can do this at a later step. See Creating self-signed certificates with PoSH.

1. On the Join Citrix Cloud or CVAD page, select one of the following:

   • Do not join
   • Join your farm with Citrix Cloud
   • Join your farm with your Citrix Virtual Apps and Desktops site

   

2. Click Next. If you choose to join your farm with Citrix Cloud or a Citrix Virtual Apps and Desktops site, then click Yes to confirm the action.

   If you select to join your farm to Citrix Cloud or a Citrix Virtual Apps and Desktops site, see the required topics:

   • If you select to join with Citrix Cloud
   • If you select to join with a Citrix Virtual Apps and Desktops site

   If you select to not join your farm, do the steps from Select the license server.

Note:

If you select to not join your farm, you see the Join Citrix Cloud or CVAD page every time you run the Configuration Wizard.

If you select to join with Citrix Cloud

If you select to join your farm with Citrix Cloud, follow these key steps:

1. Using the Citrix Cloud Registration page, register all the Citrix Provisioning Servers with Citrix Cloud. However, if a server is already registered and the registration is still valid, the page is skipped, and you directly go to the Resource Location page. If a server was previously registered, however, the registration has become invalid, then you are prompted to register again. For more information on how to register, see Register with Citrix Cloud.
2. Using the Resource Location page, select a resource location for the Citrix Provisioning target site. For more information on how to select the resource location, see Select a Resource Location.
3. Continue with the steps from Select the license server.

Register with Citrix Cloud

Once you select to join your farm with Citrix Cloud, every server needs to be registered. Registration allows all the Citrix Provisioning Servers to authenticate and communicate with Citrix Cloud without the need to log in to Citrix Cloud. To register, do the following:

On the Citrix Cloud Registration page, do the following:

1. Review the page. If this is the first server to register, the page indicates that no customer has been established for the farm yet. Otherwise, you can see the customer ID on the page that is registered with the servers in the farm.

   Note:

   All the servers in the farm must register with the same customer account

2. Click Next to start the registration with Citrix Cloud. A message appears indicating that the Configuration Wizard is registering.

On the Confirm the Citrix Cloud Registration dialog:

1. Follow the instructions as provided in the dialog to manually confirm the registration. This action requires you to log in to Citrix Cloud as account administrator.
2. After the registration is confirmed, the dialog automatically closes. Do not press Cancel unless you wish to abort the Configuration Wizard.

Note:

If for some reason, you delete an unregistered Citrix Provisioning server when all the other servers are registered, the farm’s state is still considered partially joined. To resolve the issue, run the Configuration Wizard on any of the Citrix Provisioning servers that is joined to Citrix Cloud. Select the option Farm is already configured.

Select a Resource Location

On the Resource Location page:

1. Select a resource location for the Citrix Provisioning target site. You can also select No resource location from the options if:

   • you do not use DaaS Web Studio to provision Citrix Provisioning targets.
   • you use DaaS Web Studio to provision Citrix Provisioning targets, however, not for the specified Citrix Provisioning target site.

Note:

If a resource location has already been configured for the site, and you select a different resource location from the list, you get a confirmation pop-up after you click Next.

Continue with the steps from Select the license server.

If you select to join with a Citrix Virtual Apps and Desktops site

If you select to join your farm with a Citrix Virtual Apps and Desktops site, you must select a Delivery Controller in the Citrix Virtual Apps and Desktops site that you want to join.

​​Key steps:

1. Using the Citrix Virtual Desktops Controller page, select a Delivery Controller. For more information, see Select a Delivery Controller.
2. Continue with the steps from Select the license server.

Select a Delivery Controller

You must select a Delivery Controller in the Citrix Virtual Apps and Desktops site that you want to join.

On the Citrix Virtual Desktops Controller page:

1. Review the page. If this is the first server to register, the page indicates that no Citrix Virtual Apps and Desktops site has joined the farm yet. In that case, select a Delivery Controller to establish the Citrix Virtual Apps and Desktops site that the farm will join. If this is not the first server to register, you can see the name of the Citrix Virtual Apps and Desktops site with which servers in the farm are registered.

   Note:

   All the servers in the farm must connect to the same Citrix Virtual Apps and Desktops site.

2. Click Next. The controller address is validated. You get an authorization error if you are not using a Windows login that has Machine Catalog Administrator or higher privileges on the Citrix Virtual Apps and Desktops site.

Continue with the steps from Select the license server.

Select the license server

1. Enter the fully-qualified domain name of the license server, a hostname, or an IP address if that is supported by the license server.

2. Enter the port number of License Server Port and Web Services for Licensing Port.

   Default value of Licensing Server Port is 27000.

   Default value of Web Services for Licensing Port is 8083.

   The provisioning server must be able to communicate with both the licensing server port and web services for licensing port on the license server to get the appropriate product licenses.

3. The checkbox Validate license server communication is selected by default. This option verifies that the server can communicate with the license server and that the appropriate version of the license server is used. If the server is not able to communicate with the license server, or the wrong version of the license server is being used, an error message appears. You cannot proceed.

4. Select the license to be used.

   Note:

   • If you have a DaaS (Citrix Cloud) license, then select Citrix Cloud.
   • If you have an on-premises Citrix Virtual Apps and Desktops license or are operating independently of Citrix Virtual Apps and Desktops, then select Citrix Virtual Apps and Desktops.

5. Click Next to continue on to configure user account settings.

   

Configure user account settings

The Stream and Soap services run under a user account. Configure data reader and data writer database roles automatically using the Configuration Wizard to provide database access privileges to a user account.

1. On the User Account dialog, select the user account that the Stream and Soap services run under:
   • Network service account (minimum privilege local account that authenticates on the network as computers domain machine account).
   • Specified user account (required when using a Windows Share; workgroup or domain user account). Type the user name, domain, and password information in the appropriate text boxes.
2. Click Next, then continue on to selecting network cards for the Stream Service.

Group managed service accounts

Citrix Provisioning supports Group Managed Service Accounts (gMSA). These accounts are managed domain accounts providing automatic password management and simplified SPN management over multiple servers.

Deploy certificates

You must select a certificate for all the servers in the farm if you want to:

• Join your farm to a Citrix Virtual Apps and Desktops site
• Use the Imaging Wizard for Linux targets
• Provision targets using the Citrix Provisioning API

Use the Citrix Provisioning Configuration Wizard to add the proper certificate from the local Computer personal certificates (My) store.

Note:

We recommend to use a CA-signed certificate but you can use a self-signed certificate if necessary.

For deploying a certificate:

1. Import the certificate into My store on the Citrix Provisioning server.
2. Install the root of trust of the certificate in the trusted root store of the client machines where connections are made (PVSAPI, Linux machine that is imaged and Citrix Virtual Apps and Desktops Delivery Controller).

Note:

The set of operations depends on whether you use a CA-signed certificate or self-signed certificate.

1. Run the Configuration Wizard. On the SSL Configuration page, select the certificate to use.

Use a CA-signed certificate

The CA-signed certificate must include both public and private key and the private key must be exportable.

1. Import the certificate into My store on the Citrix Provisioning server.

   Import-Certificate -FilePath <crt file> -CertStoreLocation Cert:\LocalMachine\My
   <!--NeedCopy-->
   

2. If the certificate authority root certificate is not in the trusted root store (Cert:\LocalMachine\Root) on every client machine, then add it on all client machines. However, this step is usually not required when using a public CA-signed certificate.

Use a self-signed certificate

1. Create a self-signed certificate.

   $cert = New-SelfSignedCertificate -DnsName $PVS_SERVER_FQDN -CertStoreLocation cert:\LocalMachine\My
   $cert_thumbprint = $cert.Thumbprint
   <!--NeedCopy-->
   

   Note:

   When you create a certificate, you can specify multiple -DnsName, separated by a comma. This adds Subject Alternative Names to the certificate, one for each DnsName. When using the PVS API, you can connect using any of these names. Example: You can use -DnsName “servername.domain”, “servername”. Then, using PVS API connect with -PvsServerAddress “servername.domain” or -PvsServerAddress “servername”.

2. Export the certificate to the .cer file without its private key.

   Export-Certificate -Cert $cert -FilePath $CERT_FILE
   <!--NeedCopy-->
   

3. On each client machine, import the exported self-signed into the Cert:\LocalMachine\Root trusted root store on the client.

   $file = ( Get-ChildItem -Path $CERT_FILE )
   $file | Import-Certificate -CertStoreLocation Cert:\LocalMachine\Root
   <!--NeedCopy-->
   

Use Configuration Wizard to deploy certificate

Use the Citrix Provisioning Configuration Wizard to add the proper certificate from the local Computer personal certificates (My) store.

The SSL Configuration page displays the certificate that is imported into My store on the Citrix Provisioning Server.

Tip:

When the Soap SSL Configuration page first loads, the certificate is highlighted which gives the appearance that it is selected. Ensure that the certificate is selected, it appears as a blue item in the table.

Select network addresses for the stream service

1. Select the checkbox next to each of the network addresses that the Stream Service can use. Both IPv4 and IPv6 addresses that are assigned to the Citrix Provisioning Server are displayed. You can proceed with one of the following combinations:

   • Only IPv4 address
   • Only IPv6 address
   • Combination of both IPv4 and IPv6 address

2. Enter the base port number that is used for network communications in the First communications port: text box.

   Note:

   A minimum of 20 ports are required within the range. All provisioning servers within a farm must use the same port assignments.

3. Select the Soap Server port (default is 54321) to use for Console access, then click Next.

Continue on to select the bootstrap server.

Configure the bootstrap server

Note:

BIOS targets are no longer supported. These instructions are only for configuring pre-existing BIOS targets.

1. Select Provisioning Servers to use for the boot process:

   1. Use the Add button to add more provisioning servers to the list. The Edit button to edit existing information, or to remove the server from the list. Use the Move up or Move down buttons to change the server boot preference order. The maximum length for the server name is 15 characters. Do not enter the FQDN for the server name. In a high availability implementation, at least two provisioning servers must be selected as boot servers.

      

   2. Optionally, highlight the IP address of the provisioning server that target devices boot from, then click Advanced. The Advanced Stream Servers Boot List appears.

      

      The following list describes advanced settings that you can choose from. After making your selections, click OK to exit the dialog, then click Next to continue.

   • Verbose mode: Select the Verbose Mode option if you want to monitor the boot process on the target device (optional) or view system messages.
   • Interrupt safe mode: Select Interrupt Safe Mode if you are having trouble with your target device failing early in the boot process. This option enables debugging of target device drivers that exhibit timing or boot behavior problems.
   • Advanced memory support: This setting enables the bootstrap to support newer Windows OS versions and is enabled by default. Disable this setting on Windows Server OS 32 bit versions that do not support PXE. Or if your target device is hanging or behaving erratically in early boot phase.
   • Network recovery method:
     • Restore Network Connections: Selecting this option results in the target device attempting indefinitely to restore its connection to the provisioning server.

       Note:

       Because the Seconds field does not apply, it becomes inactive when selecting the Restore Network Connections option.

     • Reboot to Hard Drive: (A hard drive must exist on the target device). Selecting this option instructs the target device to perform a hardware reset to force a reboot after failing to re-establish communications for a defined number of seconds. The user determines the number of seconds to wait before rebooting. Assuming the network connection cannot be established, PXE fails, and the system reboots to the local hard drive. The default number of seconds is 50, to be compatible with high availability configurations.
   • Logon polling timeout: Enter the time in milliseconds between retries when polling for provisioning servers. Each server is sent a login request packet in sequence. The first responding server is used. In non-HA configurations, this time-out simply defines how often to retry the single available server with the initial login request. This time-out defines how quickly the round-robin routine switches from one server to the next in trying to find an active server. The valid range is from 1,000 milliseconds to 60,000 milliseconds.
   • Log in general timeout: Enter the time-out in milliseconds for all login associated packets, except the initial login polling time-out. The time-out is longer than the polling time-out because the server needs time to contact all associated servers, some of which are unreachable. Unreachable servers require retries and time-outs from the provisioning server to the other provisioning servers to determine if they online. The valid range is from 1,000 milliseconds to 60,000 milliseconds.
2. Verify that all configuration settings are correct, then click OK.

Finish the configuration

On the Finish page, additional data about server registration is presented in the Summary section.

1. Run the Configuration Wizard to configure all the servers in the farm.
2. Click Finish on the Finish page after configuration is complete.

After you click Finish, SPN creation is done before the SOAP service starts. If the SPN creation fails, you get a warning message. The SPN creation might fail if the user running the Configuration Wizard doesn’t have the required permissions.

To work around this permissions issue, do either of the following:

• Use a different account that has permissions to create SPNs.

• Assign permissions to the account running the Configuration Wizard.

  Account Type	Permission
  Computer Account	Write Validated SPN
  User Account	Write Public Information

  For more information, see DsWriteAccountSpnA function.

Citrix Provisioning, thus, uses Kerberos authentication to communicate with the SOAP Service.

Verify Citrix Provisioning server registration

To verify the Citrix Provisioning server registration:

1. Log in to <customer>.cloud.com.
2. Go to Identity and Access Management > API Access > Product Registrations. You can see the current registrations.

Restore database

You can restore the database from a backup when using enhanced database encryption if you rotate the keys between taking the backup and restoring the database.

To restore the database when using enhanced encryption:

1. Take a backup of the database using SQL Server Management Studio when the key rotation state is Idle.

2. Restore the database.

   1. Wait for the key rotation state to be Idle if a key rotation is in progress.
   2. Stop all Citrix Provisioning Services on all Citrix Provisioning Servers in the farm - SOAP, stream process, and Citrix Provisioning API. This action ensures that all active connections to the database are closed.
   3. Restore the database using SQL Server Management Studio.

3. Get the Citrix Provisioning Servers online.

   1. Run the Configuration Wizard on all the servers in the farm. After you click Finish, the system displays a prompt to indicate that the database has been restored and key rotation is required. Click OK.

4. Rotate the key using one of the following:

   • Go to the Citrix Provisioning Console > Farm > Properties > Encryption tab. For more information, see Encryption tab.

     Note:

     After you launch the Citrix Provisioning Console, the farm icon is replaced with a warning icon. The General, Encryption, and Status tabs of Farm > Properties also display a warning message to indicate that the database has been restored and key rotation is required. The warning icon and the message disappear after you rotate the key.

   • Use the PowerShell command Start-PvsRotateEncryptionKeys. For more information, see Using PowerShell and MCLI commands to rotate encryption key.

Downgrade

If the Citrix Provisioning farm is using enhanced encryption (Cloud join: Citrix Provisioning version 2303 and later, or any join: Citrix Provisioning version 2405 and later) and if the VM needs to be reused to install an older version of the Citrix Provisioning software, then run the Downgrade.ps1 script to clear the enhanced encryption fields from the registry.

Important:

You must back up the database before upgrading to Citrix Provisioning version 2303 or later. This restores the database using the original encryption

Downgrade to an earlier release

1. Stop all Citrix Provisioning services on all Citrix Provisioning servers in the farm - SOAP, stream process, and Citrix Provisioning API.

On each Citrix Provisioning server in the farm:

1. Uninstall Citrix Provisioning server and console version 2303 or later.
2. Run PoSH script (Downgrade.ps1) to delete the enhanced encryption fields from registry values. Mention the version to which you want to downgrade.
3. (Optional) If the farm was joined to cloud then manually unregister it from Citrix Cloud.
4. Install Citrix Provisioning server and console to a version that you want to downgrade to.
5. Run the Configuration Wizard on a provisioning server. The wizard behaves as if there are no values in the registry. Select Join Existing Farm on the Farm Configuration dialog to add this provisioning server to an existing farm. Reconfigure the provisioning server.
6. Repeat the steps for every Citrix Provisioning server in the farm.

Delete registrations of Citrix Provisioning servers from Citrix Cloud

1. Stop all Citrix Provisioning services on all Citrix Provisioning servers in the farm - SOAP, stream process, and Citrix Provisioning API.
2. Restore the database from the backup.

On each Citrix Provisioning server in the farm:

1. Run PoSH script (Downgrade.ps1) to delete registry values. The script disables the features that are included in Citrix Provisioning version 2303 or later.

2. (Optional) Manually deregister the Citrix Provisioning server from Citrix Cloud.

   1. Log in to <customer>.cloud.com with an administrator account.
   2. Go to Identity and Access Management > API Access > Product Registrations.

   3. Use the ••• menu to remove registrations from Citrix Cloud.

      

3. Run the Configuration Wizard on a provisioning server. The wizard behaves as if there are no values in the registry. Select Join Existing Farm on the Farm Configuration dialog to add this provisioning server to an existing farm. Reconfigure the provisioning server.
4. Repeat the steps for every Citrix Provisioning server in the farm.
