It's been a few years since we needed to deal with this, but at the time I felt the need to improve on the built-in Blackboard import into Canvas. I tried to replicate the structure of the original course in Blackboard in a new course in Canvas as closely as possible.
My code is posted to GitHub, but has not been updated to handle Blackboard 9 exports (if they're different) or a few lingering issues.
Feel free to have at it, improve it… or just use the built-in importer! If you want to use my code and want a hand getting it cranked up and running, feel free to reach out to me.
