> OC 4.x does not fully work with an OpenShift 3.x cluster. The opposite is also true:
> In a mail on the mailing list on the 17th of October (*[openshift-sme] 4.x oc client is not compatible with OCP 3.11.*)
> {quote}
> The open shift 4.1 CLI can't get SecurityContextConstraints from 3.11 openshift. Is this expected? or we need to fix this? 
> # oc get SecurityContextConstraints restricted -o name
> error: attempt to print an ungroupified object: /v1, Kind=SecurityContextConstraints
> oc version

> API's change per each OpenShift version. You should always be sure to match the version of the CLI to the target cluster version (at least to the minor version) and have experienced errors similar to what you are receiving in the past.
