Hello @evanrude -
An archived Bb course cannot be imported into a Canvas course shell. For this reason, when moving from Bb to Canvas, we licensed a small "archive" environment from Bb so that we could restore archived courses. This has been very helpful in providing data for grade disputes and academic dishonesty investigations. If you have a lengthy data retention period or anticipate needing to restore many archived courses, I would strongly recommend connecting with your Bb representative to discuss an archive environment.
Best of luck!
