I am considering migrating to TMG 7 from an ancient copy of Ancestry Family Tree. I have may years of data collected, most with sketchy source data (I was not in the habit of citing for much of my research career). Actually, that is why I am looking at converting to TMG. I am looking at this as an opportunity to clean up and validate my data and associated sources. I have about 900 individuals in the database. As I see it, I have three possible appoaches to doing this. Can you advise me on which would work best with TMG?
1) Start from scratch(!) - Literally rekey data and be sure to capture sources cleanly and accurately
2) Import data only and build and attach sources manually
3) Import data and sources and then try to go back and clean up
Thanks.
