Thread:Project:Support desk/How to Upgrade MediaWiki 1.12 to 1.24/reply (10)

It seems very long path for me if I proceed up gradation this way. 1. Is it possible if I mirror the existing production environment without POSTNUKE (XAMPP + Mediawiki 1.12) and then upgrade the compatible PHP version needed for MediaWiki 1.24 then upgrade the current media wiki with wiki 1.24. 2. Any document which shows the proper step of PHP upgradation.
