Don't want to sound snarky, but how about an upgrade path from 3.11 to 4.x? I am a heavy Openshift user and it seems that RH just dumped whatever architecture they had with pre-4 clusters and switched to a Tectonic-like 4.x installations without any way to upgrade other than a new installation. This makes it hard to migrate with physical nodes.

There is a free tool to help with migrations from OpenShift 3.x to 4.x - https://access.redhat.com/documentation/en-us/openshift_cont...

It's not a rolling upgrade, but it allows you to move the apps, PVs, policies in as granular a manner as you wish.
