Update:
Created a sample GEDCOM from PAF4; imported that into RM6 with almost all events/facts included. The PAF to GEDCOM converter has its own peculiarities, so some data (specific dates for some events, mostly) dropped out in that stage; they were noted in a .lst file. RM did take everything in the GEDCOM, but using the .lst report to attach the dropped dates to the right people and events is a daunting prospect, though not nearly as much as entering everything.
