I made a mistake with the “shift dates” widget when I copied my last semester course into my new course for next semester. It will be a tedious job indeed to correct all the dates, manually. I read the Canvas background material but just wanted to double-check. I would like to copy the course (again) into my new course, but only click “Quizzes” and “Discussions.” Would that only write over quizzes and discussions, and not create duplicates, or cause other problems?
