If you have information in versions 2.0 to 2.31, you can either (1) convert the file into Personal Ancestral File 3.0 or 4.0. Convert the resulting file to version 5.0 or (2) create a GEDCOM file, and import it into version 5.0.
If you haven't as yet downloaded PAF 5, I would suggest that as your first step. Then read the HELP file (look under INDIV2.DAT in the Index) before proceeding.
You will find that it is far easier to use and more versatile than the earlier versions. Just come back if you need further help.
