What do I update?
CU4 provides updates to baseline components of the 1912 LTSR. Remember: Citrix recommends that you update all LTSR components of your deployment to CU4. For example: If Citrix Provisioning is part of your LTSR deployment, update the Citrix Provisioning components to CU4. If Citrix Provisioning is not part of your deployment, you do not need to install or update it.

Install and upgrade analytics
When you use the full-product installer to deploy or upgrade XenApp or XenDesktop components, anonymous information about the installation process is gathered and stored on the machine where you are installing/upgrading the component. This data is used to help Citrix improve its customers’ installation experiences.
XenApp 6.5 migration
The XenApp 6.5 migration process helps you more efficiently and quickly transition from a XenApp 6.5 farm to a site running 1912 LTSR. This is helpful in deployments that contain large numbers of applications and Citrix group policies, lowering the risk of inadvertently introducing errors when manually moving applications and Citrix group policies to the new XenApp site.
After you install the 1912 LTSR core components and create a site, the migration process follows this sequence:
- Run the 1912 installer on each XenApp 6.5 worker, which automatically upgrades it to a new Virtual Delivery Agent for Server OS for use in the new site.
- Run PowerShell export cmdlets on a XenApp 6.5 controller, which exports application and Citrix policy settings to XML files.
- Edit the XML files, if desired, to refine what you want to import to the new site. By tailoring the files, you can import policy and application settings into your 1912 LTSR site in stages: some now and others later.
- Run PowerShell import cmdlets on the new 1912 Controller, which import settings from the XML files to the new XenApp site.
Reconfigure the new site as needed, and then test it.
For more information, see Migrate XenApp 6.x.
