After all the previous steps, you can move on to upgrading the Operator itself. Upgrading the Operator is exactly the same as the initial installation, except that you don’t re-install the CRD. To re-install the Operator in all namespaces where previous instances operated on, see the relevant documentation for Kubernetes or OpenShift.
