This KB provides information on how users can make the necessary configurations from the preserve data and exclude tables module to ensure that data from the Credentials table (discovery_credentials) is migrated properly during a clone. Not having the proper configuration can result in the target instance containing orphaned records following the completion of a clone.
1. Identify all of the children tables under the Credentials table which need to be retained during clone. Here is the list of tables
2. For tables where data needs to be retained, create both and exclude and a preserve record for the main parent table as well as all of the children tables.
By following the steps outlined this will ensure that all credentials on the target stay intact during the clone and will ensure that no ghost or orphaned records are created.
