Hi there,
We got 2 nodes Exchange 2013cu21 VM in DAG, both running on Win2012 std r2 servers, in which these 2 nodes are in different sites (i.e. different subnets), let's say exch-1 in site 1, exch-2 in site 2, both VM got daily fully backup of whole VM images.
Now assumed that for very bad luck both site 1 & site 2 got disasters at the same time & fully crashed & not accessible, can I restore only exch-1 at DR site (site 3 i.e. differnet subnet) to recover my email service?
Assume at site 3 already got fully replicated AD server there, other than updating the internal ipaddr of exch-1, updating public dns records pointing to site 3, what else should I follow up to make sure the restored exch-1 workable?
No disaster happened actually, but I need to prepare for the very worst case. Many thx!
