i have an exchange 2013 with 1 dag named dag 1 with 6 servers 3 active and 3 passive and 6 database in the same datacenter.
i need to now if its possible to create a dag 2 in a second datacenter, with 3 servers and réplicate all database from dag1 to dag 2. When i have a problem in datacenter 1 i can bring on the dag 2 database online and all user make Outlook access on.
i need this because at this time i have 9 servers on the same dag with 6 server in datacenter 1 and 3 in datacenter 2. if datacenter1 is off, the move to datacenter 2 will not work because the majority of server is in datacenter 1==> are this right?
thank you for help
