You can use the GUI installer to perform an interactive upgrade of a Platform Services Controller High Availability (HA) appliance 6.0 to version 6.7. You must run the GUI upgrade from a Windows, Linux, or Macintosh computer that is in the same network as the appliance that you want to upgrade.

When upgrading multiple instances of Platform Services Controller configured in a HA environment, you upgrade the instances one by one in sequence. The following steps provide a high-level outline of the upgrade sequence.

  1. From the load balancer, disable monitoring and node membership on the primary Platform Services Controller node, and redirect all connecting clients to the secondary Platform Services Controller node.
  2. Upgrade the primary Platform Services Controller node.
  3. After you finish the upgrade, re-enable traffic to the primary Platform Services Controller node.
  4. Repeat this sequence to upgrade the secondary Platform Services Controller node, and any other HA nodes in your environment.
  5. After you have finished upgrading all the Platform Services Controller nodes, start the services on all the nodes.

For more information on upgrading Platform Services Controller 6.0 or 6.5 to Platform Services Controller 6.7 in a High Availability (HA) environment, see Knowledge Base article KB 53661. For information on Platform Services Controller compatibility regarding the use of qualified load balancers that provide a high availability service, and their requirements between versions of vSphere, see Knowledge Base article KB 2112736.

Note: vCenter Server deployments using an external Platform Services Controller will not be supported in a future vSphere release. Deploy or upgrade to a vCenter Server deployment using an embedded Platform Services Controller. For more information, see Knowledge Base article KB 60229.
