Seamless Migration from Legacy Systems to Modern Digital Banking

Led a large-scale migration from a legacy internet banking system to a modern, microservices-based architecture. The transition ensured enhanced scalability, security, and a seamless user experience while maintaining customer trust.

Client's Request and Solution

A leading bank with over 2 million users faced challenges with its legacy system, which hindered flexible updates and interface redesigns. The bank required a modern, agile infrastructure without disrupting the customer experience.

Our approach:

Implemented a parallel migration strategy, gradually rolling out new features.
Integrated AI-driven chatbots to bridge the gap between legacy and modern systems.
Utilised an API-first approach for seamless interoperability between old and new banking services.
Ensured real-time monitoring and rollback mechanisms to prevent service disruptions.

Final Results: What Did We Deliver?

A fully scalable, microservices-based banking system.
A seamless transition with minimal customer complaints and improved UX ratings.
Reduced system downtime and enhanced operational efficiency.
AI-powered customer support, ensuring a frictionless transition experience.

Outcome: A risk-mitigated, step-by-step transformation from legacy to modern banking, ensuring business continuity and long-term scalability.

Defining the Core System Architecture

Legacy banking systems often struggle with outdated architectures that lack modularity. Our strategy focused on:

Progressive feature migration to a cloud-native microservices platform.
Ensuring compliance with banking regulations while modernising data storage and processing.
Enhancing security with AI-driven fraud detection and risk management solutions.

Suggested Key Technological Solutions

Microservices architecture transforms monolithic systems into modular, independent services that offer greater flexibility.
AI-driven chatbots facilitate seamless user interactions across both legacy and modern platforms.
Real-time data synchronisation ensures secure customer and transaction data migration without downtime.
An API gateway and orchestration system efficiently manages existing and new infrastructure integration.
Automated testing and rollback mechanisms help prevent disruptions during a phased migration process.
AI-powered fraud detection enhances security both during and after the migration.

Full Migration & Optimisation

We developed a structured and cost-effective migration plan. It began with an in-depth assessment and architectural design, followed by developing and integrating core banking APIs.

Next, we progressively rolled out new features while continuously monitoring performance. The final phase included full migration, optimisation, and security enhancements, resulting in a more agile system, reduced operational costs, and improved digital banking performance.
