My current setup is:
2 x Win2003 32bit domain controllers (hardware only supprts 32bit)
1 x Win2003 Exchange 2003 32bit server
My next upgrade plan is new hardware Exchange 2007 which will be 64bit on 64bit hardware. What OS should the Ex2007 be on (in my setup) and will there be any hardware\software compatibility issues with the new Ex2007 server running in my Win2003 32bit environment? Does Ex2007 like being in a 2003 domain?
