Hi all,
I have a hopefully easy question.
We have PROD and DR sites, with 2 CAS/HUB servers in each site and 1 Mailbox server in each site with a DAG spanned across.
PROD holds all the active mailbox databases with DR with running the healthy databases.
Currently we have Exchange 2010 SP2 installed, no roll updates.
I want to install Exchange 2010 SP2 roll update 5 on the DR servers. Wait a week then install the same roll update on the PROD servers.
Would running different versions of exchange for the DAG cause any issues? Would it be better just to wait for SP3 next year?
