Upgrading Published and Virtual Desktops

Upgrade published desktops, virtual desktops and Horizon Agent, which runs inside the operating systems of virtual desktops or published desktops and Microsoft RDS hosts.

Important: This chapter does not contain information about upgrading Horizon Agent on a Linux virtual machine. For this information, see the Linux Desktops and Applications in Horizon document.

The strategy for upgrading on the type of desktop source:

• For an automated pool of full clone desktops, you must upgrade Horizon Agent individually in each virtual desktop. You will also need to upgrade Horizon Agent in the template VM you used to create the full-clone desktops. In the event that you expand the pool, additional desktops will be created using the updated template VM.
• For a manual pool of vCenter virtual machines, non-vCenter virtual machines, and physical PCs, you must upgrade Horizon Agent individually in each machine.
• For an automated pool of instant-clone desktops, you must upgrade Horizon Agent on the golden image. Then, you can propagate the new golden image across the instant-clone desktop pool by performing a push-image operation.
• For a RDS desktop pool, you must upgrade Horizon Agent on one or more Terminal Services host or Microsoft RDS host. See Upgrade RDS Hosts That Provide Session-Based Desktops.
