Today I’m updating my MediaWiki databases from 1.7 to 1.10. The process is fairly painless, just go to maintenance/ and issue “php update.php”. I had to make sure my AdminSettings.php and LocalSettings.php files were in order though.

You’ll have to upgrade if you get this error:

MySQL returned error "1054: Unknown column 'user_editcount' in 'field list' (...)".
