I eventually used the dump from phpMyAdmin. Is there any example (or some more detailed specs) how to create the mapping sections in the (import) settings.yml? My php\_forums table looks like the following: ```plaintext forum_id, MEDIUMINT(8) ... parent_id, MEDIUMINT(8) ... 3 0 8 3 7 3 9 3 10 3 11 0 12 11 13 11 14 11 15 11 17 3 ``` It seems that whichever ids I use and no matter whether I also specify the “new\_categories: ” section, the message generated by the import container is ok: creating new categories 11 / 11 (100.0%) [2803 items/min] n] creating categories 11 / 11 (100.0%) [2704 items/min] but what is created are two main categories (that were “forums” in the phpBB with the parent\_id 0) and one empty subcategory in each one of them. The procedure does import all posts but they are all "orphaned’. --- _[View the full topic](https://meta.discourse.org/t/re-migrate-a-phpbb3-forum-to-discourse/300233)._
