Thread:Project:Support desk/Upgrading a VERY old installation...

I've inherited a very old MediaWiki installation that I need to get upgraded to current standards. I've had very minimal experience with MediaWiki in the past and have been struggling a bit.

This is running on a Windows 2003 server VM: MediaWiki: 1.4.5 PHP: 5.0.4 (isapi) MySQL: 4.1.12a-nt

I'd love to get it moved over to a Windows 2k8r2 server to match the rest of our infrastructure and give the end users the current version of MediaWiki in the process.

The problem I've run into are the various incompatibilities of the existing PHP/MySQL versions with newer versions of MediaWiki. I tried jumping to 1.14.1 (the last version to support PHP 5.0) and was then going to move it to the new server with PHP/MySQL running the current version and then upgrade MediaWiki to the current version.

The problem I ran into with this approach was that everything appeared to work, but none of the links on the front page of our Wiki would work - with the exception of the tabs for discussion/history/etc.

Can anyone help with this issue or am I approaching this wrong completely? I appreciate any help...
