Upgrading an existing MediaWiki 1.13 installation to a bleeding edge Subversion installation. This assumes you installed to the default /wiki folder as suggested in the MediaWiki installation docs.
Backup database:
mysqldump -u wiki_user -p --all-databases > mediawiki_backup.sql
Move existing wiki files:
mv ./wiki ./wikiold
Download MediaWiki via Subversion:
svn checkout http://svn.wikimedia.org/svnroot/mediawiki/trunk/phase3 ./wiki
Copy LocalSettings.php & AdminSettings.php:
cp ./wikiold/LocalSettings.php ./wiki/LocalSettings.php cp ./wikiold/AdminSettings.php ./wiki/AdminSettings.php
If you don’t have AdminSettings.php:
cp ./wiki/AdminSettings.sample ./wiki/AdminSettings.php
Edit AdminSettings.php to include the mysql username & password your MediaWiki installation uses.
Run the MediaWiki upgrade script:
php ./wiki/maintenance/update.php
Done. Now updates are as simple as running “svn update” in the MediaWiki folder.
