Cumulative Update 6 (CU 6)
Release date: August 2018
Cumulative Update 6 (CU6) is the latest Cumulative Update to the XenApp and XenDesktop 7.6 Long Term Service Release (LTSR). It provides updates to seven baseline components of the original 7.6 LTSR.
How do I deploy CU6 from scratch?
You can set up a brand-new XenApp or XenDesktop environment based on CU6 - using the CU6 metainstaller.
* Before you do that, we recommend that you familiarize yourself with the product:
Peruse the XenApp and XenDesktop 7.6 Long Term Service Release documentation and pay close attention to the Technical Overview, New Deployments, and Security sections before you start planning your deployment. Make sure your setup meets the system requirements for all components. Follow New Deployments for deployment instructions.
Provisioning Services and Session Recording are available as separate downloads and installers.
What do I update?
CU6 provides updates to seven baseline components of 7.6 LTSR. Remember: Citrix recommends that you update all LTSR components of your deployment to CU6. For example: If Provisioning Services is part of your LTSR deployment, update the Provisioning Services component to CU6. If Provisioning Services is not part of your deployment, you do not need to install or update it.
Since the 7.6 LTSR release, we have added a metainstaller that lets you update the existing components of your LTSR environment from a unified interface. Following the Upgrade instructions, use the metainstaller to update the LTSR components of your deployment.

They are not eligible for the LTSR benefits (extended lifecycle and fix-only cumulative updates). Citrix might ask you to upgrade to a newer version of these components within your 7.6 LTSR environments.
Note about Windows 10:

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. For more information, see http://more.citrix.com/XD-INSTALLER.
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 XenApp 7.6 (or a later supported release). 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 XenApp 7.6 core components and create a Site, the migration process follows this sequence:
- Run the XenApp 7.6 installer on each XenApp 6.5 worker, which automatically upgrades it to a new Virtual Delivery Agent for Windows 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 XenApp 7.6 Site in stages: some now and others later.
- Run PowerShell import cmdlets on the new XenApp 7.6 Controller, which import settings from the XML files to the new XenApp Site.
- Reconfigure the new Site as needed, and then test it.
