<p>I have a kubernetes cluster with 1 master node and 4 worker nodes?</p>

<p>Is it possible to convert this cluster to openshift?</p>

<p>I would guess no. You may plan to gradually move your workloads to a new Openshift cluster.
There's also a <a href="https://docs.openshift.com/container-platform/4.4/migration/migrating_3_4/about-migration.html" rel="nofollow noreferrer">migration tool</a> which is not supporting migration from kubernetes clusters at the moment, but might in the future.</p>
