If you have migrated a course from Moodle to Canvas you still need to import the items from the migrated course into your fall course. Here are the steps:
Go into your Fall course (You can confirm that this is the course you should be working in by navigating to People in the left-side menu. If you see your students listed you are in the correct course)
Select Import Existing Contentfrom the menu on the left side of your screen.
From the Select Content Type drop-down menu choose Copy a Canvas Course
Search for your migrated course
Choose either All Content or Select Specific Content
Finally hit the +Add to Import Queue button
At this point you should see your course at the bottom of the screen along with the status of the import and a progress bar. It should only take a couple of minutes or so to complete the import.
