Finalizer from a mesh we removed two months ago, still on that one deployment's pods because the template was never updated. Removed it and rollouts are seconds now.

Self-taught, three years in, remembers exactly how confusing the first month was.
Practical habit that saves time later: set requests from observed steady state and limits from observed peaks, and only after you have watched a workload through a full weekly cycle. Guessing round numbers on day one is how everyone gets here.
Four hours is generous for two minor versions in place if you have prepared, and nowhere near enough for a first cluster swap. Whatever you plan, write down the abort criteria beforehand — at what time do you stop and roll back rather than pushing on because you are nearly there.
