MediaWiki Upgrade to Subversion

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.
