Hey All, We have just about finished exchange migration to 2003 from 5.5. (We are moving the last of the mailboxes.) I want to install a second 2003 server, as a backup, before blowing off 5.5. Anything special I should know, not forget, be afraid (very afraid) of, etc. Its a single, uncomplicated domain enviroment. Thanks, dave dsr@xxxxxxxxxxxxx
