VMware Unified Access Gateway – Upgrade

Release date: August 5th 2019

Welcome to my VMware Unified Access Gateway series. This topic will cover upgrading the UAG. Every now and then, a new version of VMware UAG is released. The newest version, 3.6, was released 02 July 2019. Prior to upgrading my existing UAG 3.5 setup, I have upgraded my Horizon environment to v. 7.9. Before I begin, I first read through the release notes posted here: Release Notes for VMware Unified Access Gateway 3.6

Second, when I check VMware Product Interoperability Matrices, I see that UAG 3.6 is only compatible with Horizon 7.9, which is OK for me as I only use UAG for Horizon pr. now.



Upgrading the UAG can be done 3 different ways:

  • Deploy new UAG and punch in all settings manually
  • Backup settings from the existing UAG’s, deploy new UAG’s and import settings
  • Deploy new UAG’s with new powershell scripts and the same ini-files used in previous deployment.

In this session I will upgrade my UAG’s using the latter method. Before I start the upgrade, I download the necessary media from My VMware




As this is a Lab, and downtime is not an issue, I simply shutdown my existing UAG’s and remove them from vSphere. If it was a production environment, I would most likely use the load balancer to redirect the traffic, before upgrading one UAG at a time. From my deployment server, where I have the ISO, powershell-script and ini-files, I redeploy UAG’s using powershell.



After the UAG’s are deployed, I verify the settings, as described here: VMware Unified Access Gateway – Configuration. I also verify the HA-setup as described here: VMware Unified Access Gateway – High Availability

Lastly, I log in to Horizon Administrator, verify the gateway settings and test logging in from an external source to verify functionality.





That concludes my session about upgrading the UAG’s.
