What we do is go through the Canvas Release Notes and check how things work in beta ahead of time. Once everything is released to production we go back through the Release Notes and double-check that certain things (mission critical or big ticket things) are functioning as intended.
I was just made aware of this InstructureCon workshop, Start and End Your Canvas Course with a SMASH!, that developed a checklist (which is attached to that community page) that might help you get started. It has separate checklists depending on your type of institution. Although it is term based, it has various items related to where one is in any given term/year. I know it's been a good jumping off point for me to help me develop a list based on our particular workflow and idiosyncrasies.
We are giving the Canvas Admins area a little bit of love (especially questions that are really, really old) and just want to check in with you. This will also bring this question new attention.
