Combine Rebuilding and Copying for Efficiency
When transitioning from the Original Course View to the Ultra Course View, you will always get a better result by rebuilding your course fresh. However, you can combine rebuilding and granular course copy from Original to Ultra to increase your efficiency. We recommend building your structure first (see the tips on using modules and creating a consistent structure), uploading files directly to the course, and copying assessments, like Tests, from Original to Ultra to avoid rebuilding them.
Once you have your course built in the Ultra Course View, it is perfectly fine to copy the entire course for a new semester.
