VMware Unified Access Gateway – Upgrade to v. 3.9

Release date: March 19th 2020

Welcome to my VMware Unified Access Gateway series. The new version of Unified Access Gateway, 3.9, was GA on March 17th 2020. In this section I will describe how I upgraded my UAG’s to v. 3.9

To check out all the new features and changes with VMware Unified Access Gateway  3.9, read the release notes from VMware posted here: Release Notes for VMware Unified Access Gateway 3.9


Prior to upgrading my existing UAG’s, I have upgraded my Horizon environment to v. 7.12. When I check VMware Product Interoperability Matrices, I see that UAG 3.9 is only compatible with Horizon 7.12, which is OK for me as I only use UAG for Horizon pr. now.


First, I download the necessary media from MyVmware.com to my deployment server. Next I export the settings before I start upgrading.


I copy the new ova and uagdeploy powershell files to my working directory


Then I edit ini-files with new ova filename


I redeploy UAG with the new ova-file using the existing ini-files. As we can see from the screenshot below, the script automatically shuts down the existing UAG and deletes it, before deploying the new UAG using the settings I defined in the ini-files.


When the new UAG is deployed and ready, I log in and have to change password, before I get access to the management UI.


I verify Horizon Settings inside UAG


When I login to VMware Horizon Administrator, I can see that the Gateways are unreachable


The reason for the error above, is that the powershell script doesn’t adjust the UAG Name with the name I put in the ini-file. (I have absolutely no idea why). I manually adjust this in the UAG System Configuration


After I change the UAG Name, the Connection Server correctly reaches my UAG’s and the errors disappears


Finally, I do a test by logging in to Horizon through the UAG to verify functionality.
