This release has changes in how to install and upgrade StoreFront. In earlier releases, when you clicked the Get Started tile in the full-product installer’s main page, the Core Components page included StoreFront. You can select StoreFront and other core components to install on the same machine.

As of this release, the Core Components page no longer contains a StoreFront check box. To install or upgrade StoreFront, click Citrix StoreFront in the Extend Deployment panel on the main page. This launches CitrixStoreFront-x64.exe from the installation media.

In the XenDesktopServerSetup.exe command, you can no longer specify /components storefront. If you do, the command fails. To install StoreFront from the command line, run CitrixStoreFront-x64.exe, which is available in the Citrix Virtual Apps and Desktops installation media’s x64 folder.


The Citrix License Administration Console reached end of life and end of support in License Server Build 30000. Use the Citrix Licensing Manager.

New deployments

How do I deploy CU8 from scratch?

You can set up a brand-new XenApp and XenDesktop environment based on CU8 - using the CU8 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 Overview, Install and Configure, and Security sections before you start planning your deployment. Ensure that your setup meets the system requirements for all components.

Existing deployments

What do I update?

CU8 provides updates to baseline components of the 7.15 LTSR. Remember: Citrix recommends that you update all LTSR components of your deployment to CU8. For example: If Citrix Provisioning is part of your LTSR deployment, update the Citrix Provisioning components to CU8. If Citrix Provisioning is not part of your deployment, you do not need to install or update it.

The following components - at the versions given below - are compatible with LTSR environments. They are not eligible for the LTSR benefits (extended lifecycle and fix-only cumulative updates).

*Browser content redirection

Redirects the contents of a web browser to a client device, and creates a corresponding browser embedded within Citrix Workspace app. This feature offloads network usage, page processing, and graphics rendering to the endpoint. Doing so improves the user experience when browsing demanding webpages, especially webpages that incorporate HTML5 or WebRTC. Only the viewport (the user’s visible area of a webpage) is redirected to the endpoint. Browser content redirection doesn’t redirect the user interface (the address bar, toolbar, and so forth) of the browser on the VDA. For more information see Browser content redirection.

Compatible versions of Citrix Workspace app

All currently supported versions of Citrix Workspace app are compatible with theXenApp and Xendesktop 7.15 LTSR. For information about the lifecycle of Citrix Workspace app, see Lifecycle Milestones for Citrix Workspace app & Citrix Receiver.

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 or upgrading the component. This data is used to help Citrix improve its customers’ installation experiences. For more information, see Install and upgrade analytics.

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 CU8. 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 CU8 core components and create a Site, the migration process follows this sequence:

  • Run the XenApp 7.15 CU8 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 CU8 Site in stages: some now and others later.
  • Run PowerShell import cmdlets on the new XenApp 7.15 CU8 Controller, which import settings from the XML files to the new XenApp Site.

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