Thread:Project:Support desk/Easiest way to upgrade from MediaWiki 1.5.4

Hi all,

I had a very old installation of MediaWiki 1.5.4 running with PHP 5.2

My ISP upgraded to PHP 5.3 which broke the installation. I have temporarily enabled PHP 5.2 to get the Wiki back up, but this is only a temporary solution.

What is the easiest way to upgrade from MediaWiki 1.5.4? I have available PHP 5.2, PHP 5.3 and MySQL 5.

I looked for the Web Updater but found that my installation does not have the mw-config folder at all and I don't have shell access.
