The Canvas migration tool does a pretty good job of moving content from our legacy ANGEL LMS to Canvas, but there can be minor issues depending on the content type.
One issue to be aware of is journal assignments using the private discussion feature in ANGEL. Canvas does not have an equivalent content item. It interprets the journal assignment as a discussion forum and creates it as such during the import process. If left as is there is potential for students to submit private journal assignments that are open to everyone in the course.
If you used private discussion forums as student journals in ANGEL, you will need to re-create these as assignments in Canvas and if submitting online choose a method like direct text entry or uploading a file.
