Case Study: Expleo helps a leading UAE bank reduce data migration testing time with QuerySurge

Expleo Automates Data Migration Testing for a leading UAE bank with QuerySurge

The customer, a leading UAE bank, faced significant challenges in manually validating data during a critical migration from Informix to Oracle. Their reliance on time-consuming and error-prone methods like Excel macros created bottlenecks and risks to data integrity. They engaged Expleo, which implemented the QuerySurge automated data testing solution to address these issues.

By deploying QuerySurge, Expleo automated the validation process, creating 6,000 test pairs to run overnight. This solution accelerated the testing cycle by 50%, reducing validation time by 3,500 hours and ensuring data accuracy across 620 million records. The implementation by Expleo resulted in substantial cost savings of approximately $131,200 and delivered an impressive 180% return on investment for the bank.
