What we want is to *clean up all the records so that the wiki can start from 0.* We want to keep the information in the pages, the pictures and other files uploaded in the wiki.
Hello,
You might give http://www.mediawiki.org/wiki/Extension:SpecialDeleteOldRevisions2 a try. I've used this extension in a similar case when moving a wiki from a development environment to a production site after importing old stuff from a usemod wiki.
