Create a course with some students enrolled. Make sure to create a couple of groups for the course. Create a couple of assignments and quizzes. Make sure that these activities have a start and finish date (preferably in this month). It may be a good idea to add the calendar block to your course. Check that events in the calendar have been created for these start and finish times. (quiz only seems to create events for start times, while assignments create events for due days). Create a course event in the calendar. Create a group event in the calendar. Back up the course without user data. When un-checking the "include enrolled users" box, make sure that the "Include calendar events" box is still checked. Restore the course (into a new course). Check that the activity events are still present, the course events and group event is restored as well. Restore the course again (into a new course). This time set the course start date a month ahead. Ensure that the activity events are now a month ahead. Additional Fred testing Create a different course. Add some events in the calendar. Make sure to add course and group events. Restore the previous course and merge it into this newly created course. Check that the events have all been merged into the calendar with no issues.
