Hello. is it possible to deploy RKE2 clusters via the Rancher UI, (v.2.6.6) running on a RKE cluster. Or does rancher has to run on a RKE2 cluster to deploy RKE2 downstream clusters? I only fount this documentation but it doesn't say how it is done in rancher. Also is it possible to update the downstream clusters in rancher to rke2 ?

The type of cluster Rancher is running in has no bearing on what kind of clusters you can create from it
