Case Study: Leading US Wholesale Bank achieves seamless merger data migration with Accelerite

Data Migration For a Leading Wholesale Bank in the US

Accelerite helped a leading US wholesale bank manage a complex data migration during a major merger and acquisition. The bank needed to combine massive volumes of data across banks, departments, and systems, including more than a million users, about 50,000 wholesale customer records, and roughly one billion data elements across 45 sources and 22 targets, all on fixed timelines with no room for delay. Accuracy, regulatory compliance, and communication across 300+ onsite and offshore team members were critical challenges.

Using its ShareInsights solution and reusable migration accelerators, Accelerite delivered a phased approach covering data analysis, implementation, QA, and validation, supported by automation frameworks, strong change tracking, and ETL architecture. The result was 80% faster test execution, zero post-integration defects across releases, a 265% increase in migrated data elements, and query execution time reduced from 80 minutes to 11 minutes, enabling uninterrupted banking services throughout the merger.
