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.
- 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.
- Upgrade the primary Platform Services Controller node.
- After you finish the upgrade, re-enable traffic to the primary Platform Services Controller node.
- Repeat this sequence to upgrade the secondary Platform Services Controller node, and any other HA nodes in your environment.
- After you have finished upgrading all the Platform Services Controller nodes, start the services on all the nodes.
