Can I upgrade to Server 2008 in stages?

I have a replacement server for my PDC/Exchange server being built right now - the replacement will continue to be the PDC.  The reason is that I want a 64-bit machine for my upgrade to Exchange 2007.  But, I'm anxious to get as much done now as I can so I don't have to rush before I go on vacation.  The PDC MUST be replaced and I'd rather have the newer/faster/better machine as the PDC and Exchange server.  Can I upgrade my backup DC and two othere servers in the domain to Server 2008, ahead of my PDC?

No such thing as a PDC in an AD domain.
You have the PDC emulator, but that is all. Otherwise all domain controllers are equal.

You shouldn't have Exchange on a domain controller. If you have more than two domain controllers leave Exchange on a member server, which is where it belongs.

You can mix domain controllers without any problems.

Thanks Simon.  

Follow up question:  If I run adprep, forestprep, etc. when I upgrade my first server, will that make any changes to the current Server 2003 servers?  Will I run these with each successive server upgrade?

Prep are domain settings. Nothing to do with specific servers. All they do is extend the domain to receive the additional objects required by the installation. The existing installs in effect ignore them.
