Precautions

  • CDM jobs carry large volumes of data, which increases the database load. You are advised to periodically delete unused jobs.
  • If a large number of jobs are delivered in a short period, cluster resources may be exhausted.
  • CDM is a batch offline migration tool. You are advised not to create a large number of small jobs using CDM.
