Moodle is a complex application with a complicated upgrade procedure. It supports over 25 different types of plugins each located in a different location in the source code. While we have automated the upgrade, do not use any more plugins than necessary to reduce update issues. On the same note, do not edit the source code of core moodle since it will be overwritten on an update.
