Hi folks! So you are looking at that new daunting Exchange migration that you are thinking about doing and you’re wondering if it’s worth it?
Well I say it is! With Exchange 2010, there is one overriding reason to migrate to Exchange 2010 from your old Exchange 2003 setup. That reason is DAG! Exchange Database Availability Groups! This allows you to have replication of your Exchange databases so there is no single point of failure.
