Hi, so this is a bit of a silly question. But I need to make sure I understood the situation correctly.
I currently have an Exchange 2010 DAG with 2 servers and I am mid way through (In the Exchange Server Deployment Assistant) introducing my first Exchange 2013 server.
The plan is to make the new 2013 server the active DAG member one of the old 2010 servers the passive member for a short term until that 2010 server is rebuilt to 2013, but that's not going to work is it? Once I migrate a 2010 user to a 2013 database, that user only exists in 2013, right?
Theres no way of adding a 2013 database into a 2010 DAG, so that if the 2013 server is down, the 2010 server will become active?
Thanks
