I’ve searched a little and I could not find a straight working answer.
I want to export all users and their bbPress(2.1.2) forums, topics and replies to another fresh WordPress installation?
If anyone has a suggestion.
I wrote a small plugin that does it for you.
You have to do it one forum at a time, but it will handle all forums, topics, replies, and users.
Export the data with a database manager. The native WordPress exporter is written just for simple blogs. It will miss data like custom tables or users without posts.
You will have to take the backup from database.
If you need bbPress data only, you can only dump this tables from your WordPress installation:
bb_forums bb_meta bb_posts bb_tagged bb_tags bb_terms bb_term_relationships bb_term_taxonomy bb_topics bb_topicmeta bb_users bb_usermeta
