Installation Help

I currently have a WAMP installation running MediWiki. I would like to use Bitnami to install Redmine as well. What is the best way to save my current MediaWiki data and install Redmine without using a second instance of the WAMP stack?

Current Installation:
Windows XP
MediaWiki 1.13.1
PHP 5.2.5 (apache2handler)
MySQL 5.0.67-community-nt
Apache 2.2

The most easy way is to install Redmine in a separate Stack.

If this option is not valid for you, you can install RubyStack and then install the Mediawiki and Redmine module apps. Then you can migrate your Mediawiki data to the new installation.
