Woah!!! What did I just read? 2013 has a 50 database limit now? When did this change?
At our company we have six Exchange 2010 servers. Due to RPO and RTO requirements, we have to create multiple D.A.G. with many databases. We're maxed right up with the primary databases, secondary copies, and a third copy as well. If the 50 GB database limit is true, then we can not upgrade to 2013 because it would mean we'd have to deploy 12 Exchange servers to do the same task. This also means that if we want a 3-copy DAG solution, we can't deploy over 16 primary databases on a single Exchange 2013 server.
I had no idea Exchange 2013 was so limited. Is this really true? Is there a workaround or is there an expectation in the next service pack that this limit will be raised?
