Moving to Ultimate Facebook from Wp-FB AutoConn

Hi, I'm moving a site from using WP-FB AutoConn to using Ultimate Facebook to login to the site. Here's the question, I have all these users that have previously connected with that old plugin. I have the facbeook UID and facebook username in the DB, which I write a script to convert to the Ultimate Facebook's needs, but can y'all help me with the format and what fields are needed. I can poke around in the DB, but figure it's better if I get your help.
