I just realized that since I'll be having hundreds of users each with their own blogs, and each game we host will need it's own blog, that a regular wordpress installation isn't going to work for me. I started to google for some plugins or anything that I could use to still be able to use WP and the first result that came back was WPMU. So, I have it downloaded, but I need to know if I can upgrade from regular WP to WPMU before I do anything. My default WP theme is somewhat modified, but most of my modifications are simplified down in to a few functions in functions.php. The files won't be much of a problem. But the database will be a problem, I have a lot of pages set up already that I don't want to lose. What are my options?
I already looked in the FAQ, by the way.
