VMware Horizon – Upgrading Horizon Connection Server to v.2303

Release date: April 5th 2023

Welcome to my VMware Horizon series. In this session I will describe how I upgraded my VMware Horizon Connection Servers to v. 2303. Previously I have shown how to do this manually, in this session I will show how to do this with PowerShell and PowerCLI, remotely from a management server. Before I start, I review VMware’s documentation describing this topic:

According to VMware’s official documentation, this should be done as step 7 in the supported update sequence.

_{Update sequence for Horizon 7, Horizon 8, and compatible VMware products (78445)}

I start out by downloading the installation media from VMware Customer Connect

First, I verify the installed version:

Before I start I make myself a little workflow as show below.

Prerequisites:

PowerShell Administrative access to the Connection-server

I first created 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 had the credentials created, I was 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 very much appreciated!)

Once the script finishes, I can now verify the new version.

With the Connection Server upgraded, I can now proceed with upgrading the Horizon Enrollment Server, covered here: VMware Horizon – Upgrade Horizon Enrollment Server to v.2303
