VMware Horizon – Upgrade Horizon Composer to v. 7.8

Welcome to my VMware Horizon series. In this session I will describe how I upgraded my VMware Horizon Composer to v. 7.8

Upgrading the Composer Server is always the first task to complete, when upgrading a Horizon installation, presuming you have a composer in your solution, that is.

The first thing I do is to disable any provisioning on pools that require composer in the Horizon Administrator. Next I make sure I have a viable backup of the server. Lastly I shut down the composer server and take a snapshot prior to upgrading.



After reboot, I login on the server and upgrade composer with the install-media I downloaded from MyVmware



Prior to installation I take a backup of the Composer Database in SQL Server Manager Studio.

I launch the Installation Wizard for VMware Horizon 7 Composer and accept the terms, Next




The default installation path looks correct according to my existing installation, Next



I enter my existing Database Information, Next



The SOAP Port and Default SSL Certificate will suffice, Next



I’m ready to complete, Install



Once the installer completes I reboot the server




After the Composer Server is restarted and all essential services are up and running, I log into Horizon Administrator and see the error below. To rectify the Certificate error, I follow VMware’s instructions here: Failed to verify Composer server certificate after upgrading to Horizon 7.x (2149331)

Having followed VMware’s instructions, I can now verify the Untrusted Certificate





When I now check my composer details, everything looks nice and green.




This concludes my composer-upgrade, I can now proceed with upgrading my connection servers, covered here: VMware Horizon – Upgrade Horizon Connection Servers to v. 7.8
