9.4 Updating the Appliance
Updating Access Gateway for Cloud to a new release is a manual process. Updating the existing appliance is not supported. The supported method of updating a node is to add a newer version node to the cluster and remove the old node.
WARNING:Always upgrade the master node last. If you delete the old master node before having a valid new master node, adding a new node to the cluster fails.
To upgrade a non-master node:
-
Take a snapshot of each node in the cluster to create a backup., including the master node.
-
Download the new version of Access Gateway for Cloud.
-
Install a new node into the cluster using the new VMware image.
