Dear All, We are planning to migrate our DC and Exchange from 2000 to 2003. We have 3 DC and one AD integrated exchange 2000. Now we are planning to migrate only Root DC and exchange 2000. I have upgraded exchange 2000 to exchange 2003. Now i need to upgrade our OS from 2000 to 2003. so i need to run the Adprep utility.Here i have two doubt now. 1. whether i need to migrate the ROOT DC first or the AD integrated exchange 2000 server? 2.which server i need to run the adprep first (either in root Dc or in AD integrated exchange 2000, or in Both)? Can anybody help ? Regards, Johnson
