I am currently running Exchange on two boxes, each box is also a DC and GC. I've been told many times this isn't a good idea and I understand why though I've never had a problem with it.
Still, I'm looking for an upgrade scenario that would take the DC off the exchange box. We can only afford two physical servers and one cloud server from our hosting company. I'm also considering full virtualization as suggested by an EE member. But right now I'd like some experts to look over the migration plan I have with two physical servers and one cloud server (to act as a backup DC). I know I lose the DAG in this scenario but I think I can live with that.
Please look over my diagram and steps and tell me if anything looks wrong. I should add that Exchange 2010 is running on Server 2008 and Exchange 2016 will be running on Server 2012.
