PS: It's free. No fees for a league like yours. Don't know how you port a team over or if you re-create it here as a new one and the commish adds in the players by hand though. Probably the latter cause of the different formatting software etc but the commish can pretty much not only choose the settings, set waiver and re-draft priority and add in the players by hand (or copy and paste if you are a lousy speller like me, heh).
If this is a keeper or dynasty league you may be best waiting until they are chosen by your league mates in the spring then re-starting the league here and adding only the keepers by hand.
