will I be able to update from Authentication Manager 220.127.116.11 to 18.104.22.168
In 2 steps; first SP1 update for AM 8.1, gets you to 22.214.171.124.0
then Patch 15 for AM 8.1 SP1 gets you to 126.96.36.199.0
Do primary first.
Replication will work, but don't wait too long to update the replicas
