Hi Kathie, I moved to Legacy 7.4 Deluxe edition in March of this year from PAF. I love the program and do all my work in it now. I also have PAF on my computer and use it to open and study downloaded Gedcoms. There is no conflict between the programs and neither writes to the others files. You won't corrupt or lose data. There were some import issues in earlier versions, but the programmers have corrected them in the current version, 7.4.0.45. The handling of locations is excellent with many useful tools including mapping. Chronology is a nice upgrade. Being able to index women by maiden name and all married names at the same time is very useful. Search is powerful and being able to work within the search results is a big bonus in my opinion. Please feel free to contact me directly if you would like tips on using the new features.
