Add oadm migrate volumesource This command confirms that all objects that contain volumeSource.metadata do not have it set. volumeSource.metadata is deprecated and will no longer be available in the next release. Thus all objects that contain a non-nil volumeSource.metadata must be manually converted to prevent data loss. The following resource types are checked by this command: * cronjobs.batch * daemonsets.extensions * deploymentconfigs.apps.openshift.io * deployments.extensions * jobs.batch * podpresets.settings.k8s.io * pods * podtemplates * replicasets.extensions * replicationcontrollers * statefulsets.apps No resources are mutated.
