You can import content from one course site to another.
Only course activities and resources are imported (e.g., assignments, quizzes, forums, etc.). No student data is imported in this process (e.g., no forum postings, no assignment submissions, no grades, etc.)
You will begin this process in the new course site. In other words, go to the site that does not have the content and begin the process of importing.
Tip: Always use the Firefox browser
