Move Course from one CoursePress Pro installation to another


We decided to create a subdomain for our Courses. We would like to move the Courses that we set up on the main domain to the new subdomain that is set up in Multisite.

Is there a way to do this? I understand there is no built in export functionality, but can you please provide a step by step guide on how we can move the Course without having to re-enter all the data?
