VMware Horizon – Upgrade to v. 2303

Release date: April 7th 2023

Welcome to my VMware Horizon series. The new version of VMware Horizon, 2303, was GA on Match 30th 2023. According to the VMware Horizon 8 2303 Release Notes, vSphere 6.5 and vSphere 6.7 are no longer supported, along with several other new features and enhancements.

IMPORTANT: Horizon 8 2303 is not supported with vSphere 6.5 or vSphere 6.7, which are both past the end of General Support.  Horizon 8 2303 Instant Clones are incompatible with vSphere 6.5 and vSphere 6.7 so you must upgrade to vSphere 7.0 or later before upgrading to Horizon 8 2303 if you are using Instant Clones.

WARNING: This Microsoft security update (KB5014754) will impact customers using certificate-based authentication such as smartcards. If you have applied this update to your windows OS and if you have not mapped certificates to one of the strong mapping types described in the Microsoft KB, then users will be denied authentication when the full enforcement mode is activated by Microsoft, currently planned for November 2023. To address this issue the Horizon 8 2306 release will allow admins to configure certificate mappings to one of the strong types from the Horizon console. If you are using certificate-based authentication, then we recommend that you upgrade to this release to configure certificate mappings. See VMware KB 91595 for details.

Anyhow, in this section I will describe how I upgraded my VMware Horizon infrastructure to v. 2303. But first, at what point in an upgrade procedure should we upgrade the VMware Horizon Components? According to VMware’s official documentation, this should be done as shown below.

Prior to upgrading Horizon, I check out VMware Product Interoperability Matrices to see that my planned upgrade path is supported.

The procedure used for upgrading is as follows:

  1. Upgrade HAProxy Load Balancer
  2. Upgrade Horizon Clients (Repository)
  3. Upgrade Workspace One Access (No upgrade available)
  4. Upgrade Connection servers
  5. Upgrade Enrollment server
  6. Upgrade Recording Server
  7. Upgrade UAG’s
  8. OSOT MDT Plugin
  9. Upgrade Horizon Agent
    1. Linux Agent
    2. Recording Agent
  10. Upgrade GPO-Bundle
