Thread:Project:Support desk/Package Extension Installation.

I am attempting to recreate a 1.11 MediaWiki into a new, 1.22 MediaWiki. I imported the pages using the Special:Import and Export pages. However, installing all of the correct and new extensions and getting them to work properly is becoming a pain. Is there a simpler way to install multiple extensions that will be compatible with MW 1.22? I'm going from PHP 5.2.5, MySQL 5.0.45 and Apache 2.2.6 to a WAMP server using PHP 5.4.16, MySQL 5.6.12, and Apache 2.4.4.
