Case Study: Atos validates a 10+ billion-record data migration with QuerySurge

QuerySurge Partner Atos helps validate a Telecom's data migration project with over 10 billion records

Atos, a global leader in digital transformation, faced the challenge of validating a massive data migration project for a large telecommunications company. The project involved over 10 billion records and a tight deadline of just a few months, making manual data validation completely inadequate. To achieve the required level of coverage, Atos needed an automated data validation solution from their vendor, QuerySurge.

The solution from QuerySurge was implemented by Atos to create a suite of 421 automated tests that validated 9.2 billion records, including a single table with 4.8 billion records. This provided the necessary confidence to proceed with a successful migration, impressing the client who is now looking to implement QuerySurge across their other data testing efforts. Utilizing QuerySurge allowed the team to validate all critical tables efficiently, a task that would have been impossible to complete manually within the project's constraints.
