The case

During the customer database migration to the new CRM, an error duplicated about 3,000 records and corrupted others: some customers have addresses swapped with each other. The old system was already decommissioned, but a 3-week-old backup exists. Meanwhile, new orders have been entered in the new system. How do you get out of this?
