Moving my site

[Minya]

We had a lot of issues with our database and other problems on our old host, thus the reason for us moving here. I'm trying to get us up and running, but had wanted to do a clean install of php-nuke and our modules (many have had upgrades, and most of our problems were with modules), and I'm running into issues with using our old database, which doesn't surprise me (the one I'm on at the moment, after hacking my header.php file to hardcode my theme since get_theme() seems broken, is that I can't seem to create a superuser). Is anyone familiar enough with the php-nuke database to be able to tell me if it's possible just to import the users, groups, posts and PMs, but leave the rest of the database "clean" ?
