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:

  1. Take a snapshot of each node in the cluster to create a backup., including the master node.

  2. Download the new version of Access Gateway for Cloud.

  3. Install a new node into the cluster using the new VMware image.

    For more information, see Section 2.0, Installing Access Gateway for Cloud.

  4. Verify all components are in a green state.

    For more information, see Section 10.3, Troubleshooting Different States.

  5. Click the old node, then click Remove from Cluster.

    For more information, see Removing a Node from the Cluster.

  6. Test the appliance to verify it is working.

  7. Delete the old node from the VMware console.

  8. (Conditional) Delete the old node from the L4 switch.

  9. Repeat Step 3 through Step 8 for each node in the cluster except the master node.

To upgrade a master node:

  1. Upgrade all of the other nodes.

  2. Install a new node in to the cluster using the new VMware image.

    For more information, see Section 2.0, Installing Access Gateway for Cloud.

  3. Promote this node to be the master node.

    For more information, see Promoting a Node to Master.

  4. Verify all components are in a green state.

    For more information, see Section 10.3, Troubleshooting Different States.
