Follow this process if you want to import an existing course from another Canvas instance (i.e. non-NUS instance of Canvas).
If you have access to the course you want to copy from and it exists in NUS Canvas, then you can copy course content instead.
- From your course Settings, click on the Export course content to download the content.
- Go to your new course, and use Import course content to import the entire course or selected content.
