A Horizon Connection Server upgrade is performed using the same installer used to perform new Horizon Connection Server installations. The following steps outline how an upgrade is performed; they should be repeated on each Horizon Connection Server in the Pod until all have been successfully upgraded:
- Double-click on the Horizon Connection Server installer EXE file to launch the installer.
- In the Welcome to the Installation Wizard for VMware Horizon 7 Connection Server window, click on Next >.
- Review the VMware End User License Agreement section, select the I accept the terms in the license agreement radio button, and click on Next >.
- Verify the installation directory (you will not be able to change it) and click on Install.
- Once the upgrade process has been completed, click Finish to close the installer window.
- In the Horizon Administrator console, navigate to View Configuration | Servers | Connection Servers window and verify that the Connection Server displays the new version number as indicated by the red arrow in the following screenshot:
Once the functionality and compatibility of the upgraded Connection Server has been verified, the remaining Connection Servers in the Pod can be upgraded using the same procedure.
In the event that vSphere VM snapshots are used to restore a VMware Horizon Connection Server to a previous state, the Connection Server will stop replicating its AD LDS database to other Connection Servers. In the event you wish to retain the configuration contained within the AD LDS database on the server where the snapshot was reverted, all other Connection Servers within the same Horizon Pod will need their Connection Server software and AD LDS database uninstalled and reinstalled from scratch. Refer to the Horizon 7 Upgrades guide (https://docs.vmware.com/en/VMware-Horizon-7/index.html) for additional information about what is required if a Horizon Connection Server is reverted to an earlier snapshot.
