Case Study: Union Bank of the Philippines achieves 100% data validation for a 1.7PB migration with QuerySurge and Expleo

Expleo executes petabyte-sized complex data migration for Bank using QuerySurge

Expleo, a global engineering and technology consulting firm, faced a significant challenge while assisting Union Bank of the Philippines with a massive data migration. Following a bank acquisition, the project involved integrating over 1.7 petabytes of data from more than 15 applications. Initial manual validation methods were cumbersome, error-prone, and threatened the project timeline, making a robust automated solution essential. Expleo, a Platinum Alliance partner of QuerySurge, turned to its data testing solution to address these complexities.

By implementing QuerySurge, Expleo streamlined the validation process, enabling seamless data comparison between source and target databases. The solution automated testing, provided insightful reporting, and allowed for continuous validation around the clock. This resulted in the successful migration of all data with 100% verification. The use of QuerySurge led to substantial cost savings of over $550,000, an impressive 228% ROI, and reduced the total validation time by over 2,000 hours.
