Hello,
We are going to upgrade RSA primary and replicas from 8.1 to 8.2 patch3. Primary and replicas are located in different regions, therefore we can not to do an upgrade within one maintenance window.
Will synchronization between Primary and replica work if Primary will be on 8.2 version but replica still on 8.1 ?
Will replica synchronized with primary while Primary upgrading?
Thank you.
To go from 8.1 to 8.2, you need to be at least on 8.1 sp1
8.1 sp1 will replicate with 8.1
8.1 sp1 will not replicate with 8.2
You also must have the primary and replica 8.1 sp1 replicating normally to start,
then install 8.2 on the primary. Primary will not allow 8.2 to install if replication is broken.
Then, once primary is on 8.2, replication will break, but the replica(s) will allow installation of 8.2.
Do not attempt to install 8.2 on a replica first, that will permanently break replication and
you would be reinstalling to fix it.
