Hi Benjamin,
i don't know any tutorial, but here is my checklist for updating Moodle which worked fine from version 1.8 -> 1.9 -> 2.2 -> 2.3.3+
- At first install Moodle 2.4 separately and test if all the plugins you have installed work fine in the new version. If not, check for updates or wait for them
- Backup your current Moodle (WEB-folder,moodledata-folder,database)
- Extract the new version on your server.
- Copy all the module-folders from your current installation to the new one. By modules i mean blocks, activities (mod), filter, questions, etc.
- Copy your theme if necessary
- Copy your config.php
- Replace the new moodle folder with the old one
- Login as admin, follow the instructions and hope for the best.
- If the update went fine i visit a course i designed containing every activity and resource so i can make sure they work !
- Celebrate your new Moodle, Yeah !!!
- Keep the backup of your old moodle for a while in case any unsolvable problems appear.
