Hi Team ,
We have three node cluster setup where the one primary server with automatic fail-over and second replica is automatic fail-over and third node is manual fail-over replica . So we have recently applied the windows patching on Third and second replica ,it is have been successfully completed hence we have moved all database into second replica ,application successfully speaking with second node as primary node . So Windows team has started patching on primary server where server is not coming up after applying the patchs and windows team is mention we may rebuild server . Could you please let me know what are process need to follow remove replica from always on availability group first ..
