I'm planning on upgrading my Auth Managers from 8.1 to 8.2. I have a primary and a replica in place. Per the documentation it says to upgrade the Primary first, then replicas. During this time will my replicas still provide token authentication to our agents while i'm in the process of upgrading the primary? I'm looking to see what type of service impact will happen during this upgrade.
thanks
Yes, though you should periodically check replication status is OK in the Operations Console - Deployment Configuration - Instances - Status Report.
Ops console is the one with port 7072 instead of 7004, something like https://rsa01.company.com:7072/operations-console
if abbreviations work, you could try https://rsa01.company.com/oc
Or configure system warnings to email you if Replication is broken.
As Long as Replication is working, the replica(s) will have an exact copy of the Primary database and can authenticate everyone. What you lose is Administrative ability while primary is down, e.g. add users, agents, tokens...
If Primary is dead, you can promote a replica to become the new primary.
