Updating your site often sounds much scarier than the actual experience is. The most important step to remember is creating and testing backups of your site. In this lesson, we will create our backups, download a new version of Drupal core, and go through the process of updating our files and running the update.php script.
Note: Not mentioned in the video is the fact that in addition to the user 1 account, you can also log in with any account that has the "administer software updates" permission enabled to run the update.php script.
