Simply point your web browser to https://yourdomain.org/wp-admin/upgrade.php

If you db is out of date, there will be a button to upgrade it. That’s all you have to do. (At least, that solved my slow back-end issues with both the 3.0 and 3.1 upgrades.)

If you’re running a network of blogs (i.e. WPMU), you can check out the wp_blog_versions table to see which blogs have had their databases updated. The db_version field should be 17056 for 3.1. If any aren’t, you can point your browser to the equivalent upgrade.php for that blog’s site and it should upgrade accordingly. (Interestingly, the last_updated field only updated on 3 of my 11 blogs. Not sure why.)

In case this helps, I found that I had the same problem upgrading to 3.1 as I did for 3.0, namely, the back-end area is incredibly slow.

For whatever reason, I have to access /wp-admin/upgrade.php manually for every blog on my network.

Disabling all of the plugins and removing the admin bar didn’t help. But once I actually upgraded the databases manually, everything was peachy-keen. Now if I can only get my sysadmin to upgrade the server…
