So the bbPress migrator did not properly migrate these as private messages? How many topics like this are there? You can use the admin wrench to manually convert topics to PMs as needed, but depending how many you have…
As far as I can tell all posts that were marked as private replies are still posts in the Discourse forum and haven’t been converted to PM’s. We’re still going through the database, but last time I spoke to my team there were 3600 posts.
I think will run the migration again and see if the same thing happens again.
There are several ways to use Discourse to manage support requests, if you’re so-inclined. Group inboxes are also a great solution for this, and keep all your users engaged in one place.
