When using both WP All Import Pro and WP All Export Pro, BBpress forums/topic/posts do not get associated properly to their authors in the new installation. Here’s the response I got from WP All Import support team a couple of months ago,
“When you import your users to the new site, they’re going to get new user IDs, so I would suggest using something other than the User ID in your {author[1]} element. You can use either their username, or e-mail address in the Post Author field of the import and it will properly link the imported posts to them.”
But without explanation on how to use WP All Import Pro with the exported file to import the Forums, Topics, and replies properly…. There are hundreds of different authors for each topic/post and their documentation is not helpful in explaining what to do either.
Some more thorough help would be appreciated, and I’m sure I’m we’re not the only wordpress users in the world that has come up against this problem before.
To add to this problem, forum orders and topic orders do not get imported. Which is required for any forum to work properly. Otherwise content is all over the place without structure.
