Hi Members,
Presently i have an Exchange 2013 CU1 DAG with two mailbox servers running on Windows server 2012.
We need to upgrade our Exchange to 2013 CU7 with two mailbox servers in DAG running on Windows 2012 R2.
I have learnt that members of DAG should be of the same Operating system level,
is it possible that i can upgrade my Exchange 2013 DAG running on 2012 to 2012R2 ?
Kind regards
