Re: importing bb_users into wp_users
I tested the change on one user, and I was able to edit his ID number to match the number from the old PHPBB. As hoped, his posts in the transferred Forum are now correctly attributed.
However, I ran ino a quirk. When I change the ID in WordPress, the user gets bumped in the User Role list. He went from “Subscriber” to “No role for this blog.” I manually promoted him to Author from the wp-admin/users panel.
What field in the wp-db controls the user roles? Can I avoid this quirk on future ID edits?
