I’ve just moved the blog over to a WordPress MU installation; it used to be running on Lyceum, but as John Joseph Bachir himself acknowledges, it’s a bit hard to keep up with WPMU, which the WordPress team participates in. There’s a difference in the database structure that doesn’t really concern me, I’m more interested in being up to date.
I’m not 100% sure that everything is going to have moved over smoothly. But we’ll see.
For the record, I did this: Exported each Lyceum site to a file, then imported it back into WPMU. I had to re-enter all the links and link categories by hand. Plus, I did what might have been a dumb thing and set up the WPMU install at a temporary URL, then tried to switch it back over by changing the Apache config file to point the /blog directory to the WPMU install. Of course, 404s were everywhere. I hand-edited wp-config.php to get /blog in there, and then from the default blog deactivated each of the two blogs and reactivated them. I also switched the theme away from the one I wanted to use and then back. Most of this seemed to repair the damage, probably due to something having been cached.
Addendum: Actually, another thing that did not go smoothly is moving all of the uploads. Lyceum had stored everything in links that looked like /blog/wp-content/blogs/2/uploads/xxx.yyy, but WPMU stores things in /blog/blogname/files/xxx.yyy. I had to manually copy everything over and then go through the posts and replace the URLs within the text. Fortunately, I didn’t have a lot (though if you find a broken link, please let me know). I also told WPMU to not use month-based directories for the files, but to just throw them all together, since that’s how I had the previous blog set up.
