Migrating SBS 2k3 to Server 2k8 and Exchange 2k7
Posted on 2009-04-06
I have gone through many of the current questions out there on this topic, and can't seem to find a solution that fits exactly what we're trying to do. I think I'm on the right track, but I wanted to get a quick sanity check.
We currenty have a SBS 2k3 server running our AD, Exchange 2k3, and Sharepoint TS. Our goal is to migrate the DC role to a 2k8 server, migrate exchange 2003 to exchange 2007 on it's own 2k8 server, and then eventually blow away the SBS server and instal sharepoint portal. I'm not concerned with the sharepoint part as it's barely used right now and anything we currently have on there I can have someone migrate manually. My question is related to the part about splitting off the DC role to a 2k8 server and then migrating exchange.
So, here's the part where I need a sanity check. Please correct me if I'm wrong.
1) Use transition pack to move from SBS to server 2k3 domain
2) Add 2k8 DC, replicate AD
3) Add 2k8 x64 + Exchange 2k7, Migrate mailboxes
4) dcpromo old SBS server
First, will doing it this way "break" exchange?
I know that I'm being quite general here, but that's the basic outline. If I'm crazy, or if anyone has come across any issues doing it this way, or if anyone has a better solution, please let me know.
