I'd just export the DB from the old server and import it into the new server. Then copy the radiant install dir over to the new server. You might need to make a few tweaks to some of the settings but it really shouldn't be any more difficult that setting up radiant the first time on the old server. IE setup radiant, using the existing code base to keep things simple, and export/import the database.
