The Challenge
The merger of Access Bank and Intercontinental Bank created one of Nigeria’s largest banking integrations, requiring the migration of millions of customer accounts into a single core banking environment with full data integrity, standardised account structures, and no disruption to customer service during cutover.
Our Approach
Fasyl led the FLEXCUBE data conversion for the merger, migrating over four million customer accounts and generating standardised account numbers across the merged entity. The engagement was delivered with full reconciliation and integrity controls throughout the cutover process.
The Results
Over four million customer accounts successfully migrated with full reconciliation and integrity controls in place. Standardised account numbers generated across the merged institution, establishing a unified customer data foundation for the combined bank following one of Nigeria’s most significant banking integrations.
Why Fasyl
A merger integration of this scale demands a delivery partner with deep FLEXCUBE expertise, proven large-scale data migration capability, and the governance to manage a high-stakes cutover where errors are not recoverable. Fasyl’s track record across Nigeria’s largest institutions made it the right partner for this engagement.
