Data Migration follows a simple workflow.

To improve the bucket listing performance on an existing bucket when using an old vault format, you must migrate data from the existing vault to the newly created standard vault using IBM COS Data Migration Service (DMS). Follow these steps for improving bucket listing performance on a standard vault:

  1. Ensure a standard vault format exists with the “Name Index Enabled” checked.
  2. Choose “Create new Vault” and “Rename Destination Vault” options when setting up a vault A1 migration.
    Note: only under these conditions when IBM COS performs DMS does it apply better index and copies bucket and object ACL, IP Access Control, Hard/Soft Quota, metadata, eTag, timestamp to the target vault.
