If I import an RKE2 cluster to Rancher, will it behave the same as one created using the Rancher interface (custom cluster)? If there are no differences after importing, then I could simply drop the cluster definition in Rancher, import RKE2 and set the cluster members (apart from installing some applications through Rancher, the only thing I did was to specify cluster members). Reading the relevant documentation it only gives specifics for K3S clusters and not for RKE2. I know that RKE2 is similar to a K3S cluster but not quite the same.
I tried importing RKE2 but it lacks a couple of features, namely the etcd snapshots or the certificate rotations and who knows what else. So the question remains: how do I reconnect to Rancher?
