In addition, unless your SUS is already running on Windows Server 2003
Service Pack 1, WSUS v3 is not even an option.
Also, there not currently a migration path from /SUS/ to /WSUS3/, and the
release date of WSUS will be long after the expiration of /SUS/ support, so
I wouldn't be looking for a formal, documented, migration path either. Most
likely the migration path will be /SUS/ to /WSUSv2/ to /WSUSv3/, so you
might as well get the first migration step out of the way before December.
