Currently we have two Exchange servers in DAG and two Domain Controllers in one data-center with dedicated Rack.
We would like to completely migrate the Exchange and AD to new data-center. The plan is to deploy/mounted the new rack in old Data-center, to migrate the data from old rack. As, There would not be any site-2-site or VPN link for connectivity between the data-centers.
After the migration the new rack will be moved to new data-center and Exchange will be running from here.
Please suggest an plan to achieve the AD and Exchange Migration and then power-up the servers in new data-center .
