Some programs have export features that allow the data to be exported in a generic format. If either one of your programs has that feature that is your best chance.But note if the two files overlap or intersect, you will still have to sort out the duplicates.Many genealogy files can be opened in a word processing program to see their file format. (Usually the data and commands are in ASCII.) If the two formats are similar, you might be able to merge and edit them. Then save them and edit the name with the correct file extension to let your genealogy program open the merged file.
