I completed my conversion to 1.3.7.1, and it gave me fits! The database was the most difficult thing ... the conversion did not go as documented.
After I finally was able to restore the database to the new system, the automatic upgrade scripts were very convenient, and I thank the zen cart team for the work they did on that.
If I can ever get comfortable with backing up and restoring the database, I think I'll be fine.
