Thread:Project:Support desk/How "upgrade" MediaWiki in Mowes Portable/reply (2)

Go through the instructions on upgrading to upgrade MediaWiki.

If you do not have PHP 5.2.3 or later and MySQL 5.0.2 or later, you must update them before. Since they are part of Mowes, you should update Mowes to get PHP and MySQL versions, which work with MediaWiki 1.19.
