Okay, I'm eating my words! In spite of all the testing we did to try to make sure that Course Copy was working correctly, I've had two reports today of problems with Course Copy.
So to be safe, I suggest you use Export/Import to copy your courses from previous semesters into your Fall containers. Export/Import has been working just fine, and only takes a couple more steps than Course Copy.
If you already tried a course copy (between Friday and today), please forward the email message you received from Blackboard to me, whether you had an error or not. This way we can get an idea of how widespread the problem is.
