Can I migrate a 2003 32-bit domain to a new 2008 64-bit server?

Is is possible to migrate Windows 2003 32-bit domain to new hardware running Windows 2008 64-Bit??  From what I read it is possible but I would need 2008 32-bit media in order to do prep the 32-bit schema.... is there any other way to accomplish this or should I just stay with 32-bit 2008.  I will also have to setup Exchange 2007 on a new server which I know only runs under Windows 2008 64bit.  How would I upgrade from the current exchange 2003 running on Windows 2003 server to Exchange 2007 on Windows 2008 64bit.   My end result would be 2 servers, one with 2008 64bit as a DC with file sharing and one with 2008 64bit member server with Exchange 2007...

You can't upgrade any individual machine to 64bit - you have to to a clean install, but there is nothing to stop you mixing 32bit and 64bit OSs within the domain. As you say you will need to prep the domain for 2008 with 32bit media - but you can use a trial version of 2008 32bit  for this.

I won't be upgrading any current hardware.... it would be migrating to all new server hardware running 64bit 2008.

In that case yes - its just like moving from 2000 to 2003, you can mix 2003 and 2008 machines in the interim, before eventually decomissioning the 2003 systems

Yes, you can migrate your system to 2008 don't think about 32-bit and 64-bit when you are thinking about domain requirements. You can have 32-bit and 64-bit machines running on the same domain. If you look below there is a link that will provide you with a step by step migration from 2003 to 2008.

On a side note I would think about using Hyper-V on the 64-bit system and installing the DC in a virtual machine instead of using the base 64-bit installation for a DC.

Why wouldn't you use the base 64-bit install as a DC?  Is there a disadvantage to this??

Darius GhassemCommented:
If you use the 64-bit as a DC then I wouldn't install Hyper-V as a service then. You want to run Hyper-V on a base install of 2008. There isn't a advantage to install a DC on a 64-bit system to be honest with you anyways. 64-bit comes into play when you are running applications like SQL.
