I’ve done quite a few of them on ubuntu, and barely ever had a site out of comission for more that 2-3 minutes. Granted I’ve tested the process on staging to ensure there are no blockers but managing a fleet of two dozen or so servers justifies the extra steps.
That’s a good strategy but only works on systems that have that option, most of what I have is colocated hardware with no luxury of spinning up new machines at will.
