2008 R2 64bit Domain Controllers & 2008 32bit Domain Controllers

I am going to be upgrading to AD 2008 and in doing so I am using 2008 R2. I have sight locations that my manager does not want me to rebuild the machine because some sites are using their DC for file shares and other things. So he wants me to upgrade the 2003 system.

Does anyone know of any issues with running 2008 R2 64bit domain controllers and 2008 32bit domain controllers?

There is no issue running either 2003 with 2008 32bit or mixed of 32 & 64 bit.
If your server is running an x86-based version of Windows Server 2003, you cannot upgrade this computer to Windows Server 2008 R2.

The only thing is you will not get benefit of windows 2008 DC,untill you have domain function level set to windows 2008 R2.
Some are the features of windows 2008 R2 are AD recycle bin,offline defrag w/o reboot,DFSR,GlobalName zone in dns,Bit locker,different password policy,Central store feature etc.
