For your existing deployment, if you deployed multiple 20.01 virtual appliances in a cluster for failover or high availability, you upgrade the nodes one at a time to 20.10

Expect some downtime during upgrade and plan the timing of your upgrade accordingly.

Procedure

  1. Take snapshots of the database and the service nodes.
  2. Remove all nodes except one from the load balancer.
  3. Upgrade the node that is still connected to the load balancer.

    The first nod that you update must reindex the Elasticsearch indices. When you see the warning message asking you to run the /usr/local/horizon/update/reindexingIndices.hzn script, select YES. When you upgrade the other nodes in the cluster, select No as the answer to this question. The reindex script is applied only on the first node.

    Follow the process for an online or offline upgrade, as described in Online Upgrading to Workspace ONE Access 20.10 or Upgrading Workspace ONE Access Offline.
    Important: Expect some downtime during the upgrade process.
  4. After the node is upgraded, leave it connected to the load balancer.
    This ensures that the Workspace ONE Access service is available while you upgrade the other nodes.
  5. Upgrade the other nodes one at a time.
  6. After all the nodes are upgraded, add them back to the load balancer.
