The server components that you must upgrade include View Connection Server, replicated servers, and security servers. Depending on the optional components you use, you might also need to upgrade View Composer.

If you spread the upgrade tasks across multiple maintenance windows, you can verify success or discover issues at each phase of the process. VMware recommends upgrading all server components during the first maintenance window.

Note: The Local Mode feature for Horizon Client has been removed, and therefore View Transfer Server instances are no longer required. In place of the Local Mode feature, VMware recommends using Mirage, which is included with VMware Horizon 6.0 and later releases. For more information, see the View Release Notes, available at
