@applem , If the old course had 750mb worth of content, then the course size limit must have been increased (the default is 500mb). To get the previous content into the new course you could increase the size limit of the new course to match that of the old. Otherwise, when you go to import the content from the old to the new course, use the option to pick specific content and only pick the content that you want/need to come over into the new course.
Our default course size is 750mb
Here is the teacher message:
I am having issues again with getting the export / import from either Canvas Export or through Commons since the course is so large. I have this warning: This file exceeds the standard Canvas Import Quota Limit of 500MB, which will likely result in an unsuccessful import. Can you copy the course for me so I can work in the sandbox?
That's strange if your default is 750mb. Have you tried it and got the same error message? If so, then you might want to contact Canvas Support to see if they have any recommendations/suggestions.
