I've been considering the options on how to perform an upgrade from 2003 to 2008 with the least amount of pain possible, and I'd like some other points of view if what I found makes sense.
We have a 30+ users setup on a single PDC that also runs Exchange 2003. The idea is to buy a new server capable of virtualizing two machines and load Server 2008 onto it. The upgrade path looks like this:
a) Install Server 2008 on new server, together with Hyper-V and the second licence as a VM.b) Join the VM to the old domain as BDC, let it replicate.c) Install Exchange 2007 on VM (possibly a different one), migrate mailboxes, etc.d) Turn off old server for a week, test everything, ensure it's all good.e) Turn on old server, decommision and then rename new server to match old server's name.
Does is seem valid? I'm a bit weary of the second step. Are there any easier ways of doing this?
