VMware Unified Access Gateway UAG 3.10 Upgrade

With the release of VMware Horizon 8 aka 2006, many are no doubt revisiting their Horizon infrastructure looking at updates across the board. We just recently took a look at the VMware Horizon 8 Upgrade of the Connection Server. What about your Unified Access Gateway (UAG) appliances? For VMware Horizon 8 2006, the Unifed Access Gateway (UAG) 3.10 appliance is listed along with Horizon 8. How can you easily go about upgrading these in production? In this post we will take a look at VMware Unified Access Gateway UAG 3.10 upgrade and see the process for upgrading your forward facing appliances with the latest and greatest version.

VMware Unified Access Gateway 3.10 New Features

There are quite a few new features to list and mention in the Unified Access Gateway 3.10 release. Be sure to check out the official release notes for the 3.10 release found here:

Unified Access Gateway Upgrade with Zero Downtime

There is a way with a built-in mechanism from VMware in the UAG appliance that you can perform an upgrade with zero downtime. VMware has a built-in mechanism in the Unified Access Gateway to present the status of the appliance as either being good for use or in a mode that is unavailable for service.

The mode is called Quiesce Mode. This is a simple toggle button that is found under the System Configuration of your Unified Access Gateway that sets the status of a resource URL so that Load Balancers can accurately recognize the availability of the appliance.

Sitting behind a load balancer, you can then set the health check for the load balancer to this resource URL so that any new requests that come into the load balancer destined to this UAG appliance will be sent to another UAG appliance. In this way, you can effectively take the UAGs in and out of service. What are the prerequisites for this operation?

  • You need at least 2 Unified Access Gateway appliances configured behind a load balancer
  • You need to configure your Load Balancer health check URL for the appliances to the specialized health check URL controlled by the Quiesce Mode toggle.
  • The URL to configure for the health check is a GET request to the URL: “https://mycoUnifiedAccessGateway.com:443/favicon.ico”.
  • It is important to understand this is the only URL that is supported by VMware to be used as a valid health check URL for determining the state of your UAG appliance.

The deployment utility will automatically power on the appliance. Login to the web interface of your new Unified Access Gateway 3.10 appliance.

Login to the new UAG 3.10 appliance

Choose to Import Settings > Select.

Import the JSON file backup that you took of your other appliance

Browse to and select the JSON file that you downloaded from the export process of your older appliance. If you had RADIUS configured, you will need to reenter your shared secret password. Once you are ready, click the Import button.

Choose the JSON file and enter your RADIUS shared secret

Now that your settings are imported, you can give these a once over and make sure everything looks correct and you have no “red” bubbles on your Horizon configuration. Finally, the settings you exported will restore to the new appliance with Quiesce mode enabled. Once you verify everything, you can now disable the Quiesce Mode so the appliance will be back in operation.

Turn off Quiesce Mode on your new Unified Access Gateway 3.10 appliance
