SD - I believe I emptied that table on the BellaOnline forum a few years ago. I think I had to make a code change to stop errors after that. I also think it caused some issues with broken links. In the forums themselves people often refer to another thread for more information. So I believe those referral links made when we were running v6 stopped working. So I think I'd like to keep the import map here so that doesn't happen.
If it's keyed on post ID, and there's no other concerns, then I'll run a query to look for any rows that don't have a matching post ID in the live posts table, and delete those. That sounds like it'll do what I need and speed things up further.
