I'm a big fan of the opposite, nuclear approach - never upgrade. Always build new system/cluster/database/whatever on the side, test it as long as you like, then flip the traffic over. It is both much easier and hella lot harder (at different times in the lifecycle), but in the end it pays off. It's not always possible, but when it is, I'm on it.

This is the approach I prefer for upgrading when able. But you should still be exercising this approach regularly when possible. You’re still upgrading to new versions, you’re just not upgrading live systems. At least with k8s, this approach is often sadly somewhat tough.
