  title: Amazon Data Lifecycle Manager Reconfigure Schedule
  summary: Read a policy, re-enable and rewrite its snapshot schedule, then confirm the change.
  description: >-
    Adjusts the snapshot cadence and retention of an existing lifecycle policy.
    The workflow first reads the current policy to confirm it exists, branches on
    whether the policy is already ENABLED, patches the policy with a rewritten
    snapshot schedule and ENABLED state, and finally re-reads the policy to
    confirm the new schedule and state were persisted. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
