Transition from Server 2003 x64 Domain Controller to Server 2003 x86 Domain Controller

I plan on transitioning from one Windows Server 2003 X64 domain controller to 2 Windows Server 2008 X86 domain controllers. I know it seems backwards to move from X64 to X86, but I am starting in a new job, and this is what I'm given to work with.

I'm just wondering if anyone knows of any issues moving from X64 to X86 servers. I know there are two different versions of ADPREP for the different architectures. It's not going to be an in place upgrade either, I'm going to add the two 2008 domain controllers to the environment, and once I have everything switched over, the 2003 DC will be removed. Thanks in advance.

The two different adpreps are for 2008 R2 for 2008 it should still be the single adprep.

Do the new servers not support x64...they should.  Sucks that is what you have to do.  First time I've seen anyone having to go from x64 back to x86.

Thanks

They new servers do support X64, it's the licenses of server 2008 that are X86.

ok got you, you may want to emphasize the benefits of x64 (memory support being the biggest) and going to 2008 R2 can get you nice features such as the recycle bin, features here

Like Mike said that the new R2 version is only 64-bit.

There is no problems going from a 64-bit to a 32-bit system.

Ya, I would definitely be moving to 64 bit to make use of those advantages if I could. But what I've been given is a couple servers that could run the x64 version, but they only have x86 licenses of Server 2008 for whatever reason.

If you have x86 license then you have 64-bit licenses as well. If you purchased Windows 2008 server you can install either one.

I wasn't aware that the license works with both x86 and x64. Thank you for the advice, I'm going to download a copy right away.
