Thread:Project:Support desk/MW1.16.1 Data Migration to MW 1.22 - How to Migrate?/reply

Hi!

That's easy: Basically you do not have to (manually) migrate anything. You run the update script update.php and it does all the magic for you. All the details are on page upgrade! Continue asking here at the support desk, if you have questions!

Note that you have to update PHP to version 5.3 or newer to run MediaWiki 1.22.
