I'm sorry, but we currently do not support directly migrating OpenLearning courses to Moodle. This is because OpenLearning differs in its functionality to most other learning platforms. However, you can manually copy and paste the contents and activities from your OpenLearning course to Moodle one by one. 

We recently launched a new product called CourseMagic, which allows you to create a course using AI and download the content in a common cartridge. You can upload that common cartridge file directly to Moodle to create a course. This feature is not limited to Moodle, as it also supports any LMS that accepts common cartridges, such as OpenLearning and Canvas.
