VMware Horizon – Upgrade Client repository with Horizon 2212 Clients

Release date: January 20th 2023

Welcome to my VMware Horizon series. Upgrading the Horizon Client is the first step in upgrading a Horizon environment, as shown below. As the Horizon Client is distributed in all kinds of different ways to users, GPO, application deployments, scripts, I won’t go into this now.

In a production environment, it is advisable to have the users upgrade their clients first. A smart approach to doing this, is to alert the users of this by using Client Restrictions. The newer Horizon Client editions are backward compatible and it is preferable to have as many as possible upgraded before upgrading the rest of the Horizon components. This can bee done by editing the Client Restrictions under Global Settings in Horizon Administrator GUI.

In my setup, I will block clients older than 8.5.0 and send warning to users on this version.

In my lab, I use the Horizon Portal to distribute clients. Previously, I have created this distribution point manually. In this session however, I will show how to do this using PowerShell.

Prequisites:

  • PowerShell Administrative access to the Connection-server
  • Pre-downloaded client binaires to network share
  • Pre-configured portal-links-html-access.properties file

I first create the following credentials to be used in the script:

  • vCenter admin-user:
New-VICredentialStoreItem -User <user> -Password <user> -Host <server> -File C:\<your location.xml>
  • Horizon admin-user:
$credential = Get-Credential
$credential | Export-CliXml -Path '<path>\hz_admin.xml'

Now that I have the credentials ready, I am good to go. (PS: I know I’m no programmer and a lot of this script have the potential for improvement, but, it gets the job done, and that’s good enough for me. If You have input to making this script even better, please leave a comment below, it will be greatly appreciated!)
