I moved my blog to a new host. I was still using 2.8.5 on the old host, and I figured I'd save myself some trouble by installing 2.9.2 on the new host and just importing my custom content and my MySQL databases.
My shortcut sort of worked -- the main page of the site and the dashboard look great. However, on the public page the links to comments, categories, etc., don't work. I presume that's because I never made the database changes.
I tried to fool WordPress into upgrading the database by running /wp-admin/upgrade.php with db_version 11548 entered in the wp-options database, but that didn't work. (I got an error message saying I was already up to date.) Can I upgrade the MySQL database structure manually?
