We have a 2-way master production cluster actively running 2.4.39.
We are wanting to upgrade to 2.4.41 (we haven't yet internally
certified 42). What is the best practices around upgrading this
cluster while keeping at least one of the servers online? Is it
replication-safe to have one node on 2.4.39 and one on 2.4.41 for a
short period?
If not, I can temporarily comment out the syncrepl statements until
both servers are on 2.4.41 and then reenable replication after both
are upgraded. We can live with short inconsistency period between
the servers during the upgrade of the servers until we can resume
replication. Also, is the DB format fully compatible between these
two versions or would it be better to reload the DB new from an LDIF
backup on 2.4.41? Is there an upgrade doc somewhere that discusses
these issues?
Thanks.
