If the name of the Course Template has been changed and you still need to roll the course over, you can do this.

1. Make sure the Course Template for the new Course name exists. If you haven't gotten the Course from your Registrar, you can create it manually.
2. Create a new Section of the existing Course (refer to Add New Section).

In that new Section of the existing Course:

1. Go to Options [Gear icon] > Edit Settings.
2. Change the Course Name (which refers to the Course Template) to match the new Course name.

Once you have done this, you can continue rolling over the Course as usual.
