Delete Migration

You can use the Delete Migration function in the Data Migration Tool to remove data in the target system that does not exist in the source system. You can do this by creating an outbound migration in the source system that becomes the master copy.

During import to the target system, the Data Migration Tool compares the source-system generated file with existing data in the target tables.

Records in the target system that are not in the source file are marked for deletion. When the import is run, the rows in the target that are not in the source migration file will be deleted.

Note: You cannot rollback a Delete Migration. Additionally, if a record already has been used in transactional tables, then it cannot be deleted.
