We have a small forum that we created and copied the database from one of our larger forums thereby duplicating many of our members in both forums. After six months we closing the smaller forum and plan to use ImpEx to merge members, threads and posts into the larger forum. There are approximately 25,000 duplicate members in the two forums since we copied the database. I would skip merging the members, but there are several hundred new members we would like to merge to the larger forum and not lose them.
What happens to those duplicate members being merged... particularly in the case of some profiles being different, passwords being different... maybe even different emails, etc., etc.?
