I have a W2K AD domain with Exchange 2K. I have successfully brought a 2003 DC online and am preparing to remove my other 2000 DC's, one of which runs Exchange 2K. I was getting ready to transfer FSMO roles to the new 2003 DC in order to remove the non-Exchange 2000 DC from the domain. Are there any hiccups with moving the Schema, Operations master and other FSMO roles from 2K to 2003 with Exchange 2000 still in the mix?
