Upgrading DMZ Gateway in a Cluster

This topic discusses upgrading DMZ Gateway in a cluster. If you are performing a clean installation (not an upgrade) of DMZ Gateway into a cluster, refer to Installing DMZ Gateway in a Cluster.

To upgrade DMZ Gateway in a cluster

1. Obtain the new installation file(s).

2. Bring down the cluster (from within the cluster manager). It is critically important that DMZ Gateway service is STOPPED on both nodes!

3. Verify that the DMZ Gateway service is stopped by logging in to each node and inspecting the service control panel. For extra assurance you can change the startup type to Manual from Automatic. (Make sure to switch it back before you bring the cluster back up in step 7 below.)

4. Run the installer on the first node and select Upgrade when prompted.

5. Run the installer on the second node and select Upgrade when prompted.

6. If you changed DMZ Gateway service startup to Manual in step 4, change it back to Automatic.

7. Bring the cluster back up.

8. Verify the upgrade was successful:

   1. Verify that DMZ Gateway is running on the primary node.

   2. Disable the primary node and verify secondary node starts up.

   3. Open the DMZ Gateway administration interface and verify that the version number is the same on both nodes (click Help > About).
