We need to figure out the process for switching from eqiad to codfw and back in our current hot/cold setup. We previously did something similar for the pmtpa->eqiad switchover, but this is wildly out of date by now. We'll need a new checklist and one we should keep up-to-date going forward.

"we should keep up-to-date going forward" is not really a finite actionable task, I would consider this Resolved. There are multiple things to fix- but on the process itself (e.g. better database orchestration), not only on the documentation.
