New deployments

How do I deploy CU1 from scratch?

You can set up a brand-new XenApp/XenDesktop environment based on CU1 - using the CU1 metainstaller. Before you do that, we recommend that you familiarize yourself with the product:

Peruse the XenApp and XenDesktop 7.15 LTSR (initial release) section and pay close attention to the Technical OverviewInstall and Configure, and Security sections before you start planning your deployment. Make sure your setup meets the system requirements for all components. 

Existing deployments

What do I update?

CU1 provides updates to 13 baseline components of the 7.15 LTSR. Remember: Citrix recommends that you update all LTSR components of your deployment to CU1. For example: If Provisioning Services is part of your LTSR deployment, update the Provisioning Services components to CU1. If Provisioning Services 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. For more information, see

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 7.15 LTSR CU1. 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 7.15 LTSR CU1 core components and create a Site, the migration process follows this sequence:

  • Run the XenApp 7.15 CU1 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 XenApp 7.15 LTSR CU1 Site in stages: some now and others later.
  • Run PowerShell import cmdlets on the new XenApp 7.15 CU1 Controller, which import settings from the XML files to the new XenApp Site.

Reconfigure the new Site as needed, and then test it.
