The WordPress Codex site’s MediaWiki installation is currently on 1.4.8. I was listening to some discussion on the wp-hackers list, so I thought I’d present my guide to upgrading. I must warn you first though, I personally use DokuWiki when I need a wiki, as it’s simpler. Without further adieu…

1. Extract everything in mediawiki-1.11.0/ into your current MediaWiki folder (i.e. replace the files)
2. Delete the following files:
   • .cvsignore
   • Version.php
   • irc/
   • docs/deferred.doc

3. Rename LocalSettings.php to LocalSettings.old.php (Important: maintenance/upgrade.php will not work)
4. Run the installer again, with the same options as before
5. Delete config/LocalSettings.php
6. Rename LocalSettings.old.php back to LocalSettings.php
7. Done!
