There is requirement to shutdown one of our data center where we have exchange 2013, with 4 mbx and 2 cas, 2 ET servers. With almost 2000+ mailboxes for different customers in shared Databaes. Also we have opportunity to upgrade the version to 2016/19? How can we
Extend or switchover existing DAGs from exchange 2013 (datacenter A) to exchange 2016 (Datacenter B), is this possible? if yes what are the steps :-)?
