 # Optional settings to specify saved object types to be deleted during migration.
 # This feature can help address compatibility issues that may arise during the migration of saved objects, such as types defined by legacy applications.
 # Please note, using this feature carries a risk. Deleting saved objects during migration could potentially lead to unintended data loss. Use with caution.
