(Note: You need to upgrade to Moodle 2.2 before upgrading to 2.4.)

Go to Settings > Site administration > Server > Environment

Status OK for everything? Great! Go to step 2...

Any problems? You probably need to upgrade your server software (such as PHP) to a more recent version.

Step 2: Be prepared!

As usual with any large upgrade, you should always be prepared to "roll back" if there's an issue with your data or some custom code you've added.

A test install
We highly advise you make a copy of your production site to practice the upgrade on first. That way, if you run into any problems that need fixing you won't affect your main site.
Always make backups
When upgrading your production instance, make sure you have copies of everything, just in case. Full instructions are here: Site backup.

Step 3: Replace your Moodle code

At this point you can replace the Moodle code on your server with the version you downloaded.

Check plugins
Any plugins you have installed will also to be replaced with a version for your new Moodle version. If there is not yet an updated version of the plugin available, it will need to be uninstalled before upgrading your site.

Step 4: Perform the upgrade!

Trigger the upgrade by visiting the admin page.

If you have a large site this may take hours, so we recommend upgrading via command line.
