I don't know. Maybe.
But what is easier after three months?
Categorize each thread and move it into the just created apropriate subforum, in the hopless effort to tidy up the mess, or just batch move all threads out of their subforums, and then delete resulting empty subforums?
Which work will you choose, if you have to do one of these?
