Thread:Project:Support desk/Pointing new install to content

I wasn't able to updated from my previous version (1.21) so I just installed the new version in a separate subdirectory. I gave it the same database and permissions, but it doesn't display the actual wiki content. How do I "point" my new installation to the content that I already have entered? Is this in LocalSettings? I saw something about exporting an xml file, but not sure how to get it in the new install,

A problem is that I'm inexperienced and am not sure how to run scripts. I can't find where to enter them. Thanks, Jonathan
