Can I share content across Realms?
Currently, there isn't a way to pass a course from realm to realm. There is, however, an "Export Course" option at the bottom right of the course home page. Check out the screenshot below.
You can export the course and upload the file into whichever realm you choose. Please note, when you import the course into a new realm, your property settings are not saved.
And as a reminder, check out this article on how to create a new Realm.
