      When installing a new Istio control plane revision the previous resource validator will remain unchanged to prevent
      unintended effects on the existing, stable revision. Once prepared to migrate over to the new control plane revision,
      cluster operators should switch the default revision. This can be done thorugh `istioctl tag set default --revision <new revision>`,
