I've seen the warning about connecting an rke2 cluster to a different rancher cluster but there's some ambiguity. It makes sense that it's unsafe to have rke2 connected to two functioning rancher instances. Is it safe, though, to 'move' an rke2 cluster to a different rancher instance? In other words, if I delete the original rancher cluster and build a new one, can I wire the existing rke2 cluster up to the new rancher and continue on from there?
