A successful migration should have its Succeeded condition set to true. Get the StorageVersionMigration object as follows\n\nBounded code example (external data; do not execute automatically):\n```shell\n  kubectl wait --for=condition=Succeeded storageversionmigration.storagemigration.k8s.io/secrets-migration\n``` …\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
