Thread:Project:Support desk/Is it possible to just transfer articles and uploaded files within different wiki versions?

In order to make a specific extension work I have to go to a previous version of media wiki. A downgrade screwed up my database so that is no solution. Now I could set up a new wiki with that particular version and just copy article after article but that would tage ages. Is there a chance to just manually copy files from the server of the old wiki to the new one so that all the articles and pages are accessible? Thanks in advance
