We have a machine that has been chugging along with the burden of both Exchange and DC and DNS all with SBS 2008.

We have a better machine now and I'd like to move Exchange 2007 to that machine and take it off of this machine. In fact, I'm planning on formatting the old machine and get rid of SBS all together because it is making the machine SLOW.

How would I go about making the move?

I've read on previous versions of Exchange (2000), that all you do is install Exchange on the new machine and then start moving mailboxes one after the other.

Well, what about all the different rules we have in place? How do those get moved? How do we de-commission the old exchange and set up the new exchange as the primary one? Come to think of it, how do we have both exchanges recognize each other on the same domain?

TIA
