Global Bank Achieves 65% Faster Core Banking Migration with AI Agents
How a Fortune 500 financial institution migrated 15TB of mission-critical banking data from mainframe to cloud in 4 months instead of 11, saving $2.4M while maintaining 100% data accuracy and regulatory compliance.
Company Background
A Fortune 500 global financial services institution with operations in 45 countries, serving over 50 million customers. The bank processes billions of transactions annually across retail banking, commercial banking, and wealth management divisions.
Their core banking system ran on legacy mainframe infrastructure for over 30 years, creating challenges with scalability, innovation velocity, and operational costs.
The Challenge
Migrate 15TB of mission-critical core banking data from mainframe to cloud while maintaining zero downtime and full regulatory compliance.
Complex Data Structures
Over 2,500 tables with intricate relationships, stored procedures, and business logic embedded in the mainframe system.
Regulatory Requirements
Must maintain SOX, PCI-DSS, and Basel III compliance throughout migration with full audit trails.
Zero Downtime Requirement
24/7 banking operations across global time zones meant no maintenance windows for migration.
Timeline Pressure
Mainframe support contract ending in 12 months, creating hard deadline for migration completion.
The Solution
DataMigration.AI deployed a comprehensive AI-powered migration strategy using specialized agents for profiling, mapping, validation, and reconciliation.
Phase 1: Automated Discovery & Profiling
Profile AI analyzed all 2,500 tables, identifying data types, relationships, dependencies, and data quality issues in 2 weeks vs 3 months manually.
Phase 2: Intelligent Mapping
Map AI automatically generated transformation rules for 95% of tables, with human review only for complex business logic.
Phase 3: Continuous Validation
Quality AI performed real-time validation during migration, catching and correcting issues automatically before they reached production.
Phase 4: Automated Reconciliation
Reconcile AI verified every record post-migration, generating compliance reports automatically for regulatory audits.

DataMigration.AI's AI agents transformed what we thought would be an 18-month nightmare into a 4-month success story. The automated profiling and mapping saved us months of manual work, and the continuous validation gave us confidence we'd never had in previous migrations. We achieved 100% accuracy with zero downtime—something our previous vendor said was impossible.
