...And I have a counter-anecdote. We had someone wanting to do just what you do - one patch at a time on HP's C7000 Chassis. I believe it was the Virtual Connect firmware, going from 3.50 to 3.55 - in the patchnotes they'd revised it saying "don't use this version, its busted - go straight to the latest!' - that wasn't caught and we had unplanned downtime, and the person involved worked a 21-hour day to get it back up and running.
We've since doubled the number of chassis involved so we can live-migrate everything off a given chassis for when it gets updates so this doesn't happen again. Along with reading ALL of the patch/release notes.
