EXCH2013 and DAG
Posted on 2016-10-19
I have one more question about DAG.
I have to Migrate EXCH2007 to EXCH2013 and I want to do this with coexistence.
Now I have installed 3 EXCH2013 servers. On all servers I can see mounted DBs, I think these are the DBs from EXCH2007 , right ?
My question is, when to deploy the DAG with my 3 nodes ?
Can I also do this after the migration ? Because now the old DBs of EXCH2007 are visible.
Or is it better to create the DAG in the beginning ?
