How do you know whether to do a straight Import or Backup and Restore?
If your course has a lot of date-specific material, such as assignments with specific due dates, we recommend using Backup and Restore. Otherwise, it is far simpler to Import.
Important Note: You will typically uncheck "include enrolled users" while backing up a course.
Once you Import or Backup and Restore, make sure to check dates and update your material.
