Convert Joomla / Joomsuite Member users to Amember

We need a SQL command or script to convert a 310 member user database from Joomla (and Joomsuite Member) over to a new aMember database on the same server. Things we'd like converted - Username,? full name, email address, subscription start date, subscription end date, plan type (we have 3 types of subscriptions plans) and password if possible. No work needs to be done on the amember or joomla sites themselves, just a database conversion.
