I would first make a backup of your PAF file using a completely different name. In case the worst happens and your file you are using becomes useless. Then go to the Genealogy Center with your file and they will show you how to convert it and also update any temple work that has been done on your file. Look for new temple work by running a completed and uncompleted temple list. It is a good way to find out if another sole out there unknown to you is doing your line.
