So we have 3 DAG member as mailbox server and 2 as our CAS/Hub - Total of 5 servers. All Exchange 2010 Enterprise. Our 3 mailbox servers have 3 databases each, all replicated between each other.
I need to come up with a DR plan to have a server or two across the ocean in another data center. Is there an easy way to just add a CAS/Hub and a mailbox server and make it part of the DAG?
