My long relationship with MediaWiki is over.  It’s been over for a while if I’m honest.

Anyway, there’s no trivial way to import MediaWiki data into Bookstack but here’s what I did:

1. First I installed Bookstack.
2. Then export MediaWiki data to xml:
   

   php maintenance/dumpBackup.php –current –include-files > /tmp/all_pages.xml

3. Clone https://github.com/outofcontrol/mediawiki-to-gfm
   

   ./convert.php –filename=/tmp/all_pages.xml –output=/path/to/converted/files

4. Find where your images went:
   

   php maintenance/dumpUploads.php

5. Clone
   

   https://github.com/Yetangitu/bs

6. Go to your bookstack implementation and get an API key.
7. Follow the instructions for ‘bs’ to configure it with your API key.
8. use ‘bs’ to create books/chapters/pages using the data from step 3.
9. Upload the images from step 4.
10. A bunch of manual cleanup and reorganizing.

This is not for the faint of heart but it’s also not difficult.  Just a bit tedious.
