If you want to copy all the course content into a new course shell for a new semester or school year, you can do a Copy Course. You must be the course editor in both courses.
In the new course, go to Manage > Import Console > Copy Course.
On the next screen, choose the course that is to be copied from the drop-down menu. It is a good idea to keep "Backup courses before import"checked. You may not need to check "Replace all existing content" if the course that is being copied over has no content within it.
Click Copyto finish. You will see a confirmation screen that tells you that the course is being copied.
Once the course has been copied, the "Import History" screen will display a record of the import.
