Hi,
I'm looking for a little advice regarding a vCenter upgrade from 6.0 U3b to 6.5. Our architecture comprises of two VCSA servers, both with their own external PSC. They were deployed in the following order:
1) PSC1
2) VCSA1
3) PSC2 (setting PSC1 as the replication partner).
4) VCSA2
From the recommended topologies from , ours is closest to this:
although technically, it's more like this:
What I can't recall is how exactly these are setup with regard to single sign on, primarily because I've found the documentation confusing (they are configured to work against Active Directory for signing in, but I don't remember if this was done on both PSC nodes or just the primary and then it replicated that data).
They were all deployed via the command line, using JSON files for the configuration. 'vsphere.local' was specified for the 'domain-name', and 'Default-First-Site' was specified for the 'site-name' for *all* 4 servers. As I understand it, this would make them all part of the same site.
Documentation seems to suggest upgrading the PSCs first. So would that be upgrading PSC1 and then PSC2? I'd assume that upgrading PSC1 would break the replication between PSC1 and PSC2, until PSC2 was upgraded also?
After this, I would look to upgrade VCSA1 and then VCSA2.
Can anyone else confirm whether this would be the correct approach?
Thank you.
