Upgrading 6.5 VCHA with external Platform Services Controllers

[rezaa]

Hey Community,

I wanted to confirm the upgrade steps for vCenter 6.5 with external platform services controller and VCHA.

In my configuration I have two platform services controller that sit behind a load balancer, and vCenter is configured with VCHA utilizing the load balancer's VIP for connectivity to the platform services controller.

In order to do the upgrade I figure the steps would be as follows

PSC:

1. Snapshot both Platform Services Controllers
2. Login to PSC 01 on the management interface, conduct the upgrade through the webgui and reboot
3. Login to PSC 02 on the management interface after PSC 01 is back online, upgrade through the webgui and reboot

vCenter

1. Snapshot all 3 vCenter virtual machines (witness, peer, primary)
2. Put VCHA cluster into maintenance mode
3. Patch the witness node (attach ISO to VM and execute 'software-packages install'. Reboot after patch
4. Patch the secondary (peer) node and reboot.
5. Fail over cluster to secondary node after its back online
6. Patch the primary node and reboot
7. Fail cluster back to primary node (optional)

I didn't find a KB or blog article specifically outlining the upgrade steps for this configuration.

Thanks for validating.

The "easiest" way to do this would be to disable HA before running the upgrade on the primary. This may take some more time, though reduce the risk of the nodes not coming back and having to reconfigure it anyway.
