Admin presets block is a Moodle plugin which allows you to simply export the site settings to .xml presets, import and load other sites presets. The plugin which was initially developed by David Monllaó, is now being maintained by Clément Prudhomme & Nikolaos Papoutsis. Recently, the Admin presets plugin was updated to a new version compatible with Moodle 3.3 version.
By using the admin presets block, you can export all the site settings into .xml files which can be later imported to other Moodle sites. It also provides rollback of applied changes and partial loading of presets which is a great feature for administrators.
