We have been using Canvas for 5 years and now it is a time for us to think about clearing our system from old courses. Instructors and Students started complaining about the long list of ALL COURSES and asking to remove some. Copying and searching courses also became more cumbersome. We also trying to avoid exceeding the total space quota. 

Could you please share how you deal with this process? What are your policies? Do you delete courses from the system? How long you keep them before removing them from the system? Is it possible to permanently remove them from Canvas and if it is, do you archive them first in bulk or have instructors to make their own archive? It would be great to hear about the best practices in archiving, hiding, and deleting old courses on account level.  Thank you.
