Modernizing Legacy Business Applications from Visual Basic 6 to .NET for Enhanced Security and Efficiency

The client is facing the end-of-life support for legacy applications built on Visual Basic 6, which poses risks to operational stability, security, and future scalability. Due to limited internal resources for technology upgrades, the client needs external expertise to migrate critical applications to modern, supported frameworks while ensuring data security and minimal operational disruption.

A mid to large-sized financial institution serving millions of individual and corporate clients, managing a robust suite of core banking applications built on outdated technology.

• Replace legacy Visual Basic 6 applications with modern, supportable technology stacks.
• Improve operational efficiency by significantly reducing maintenance time per application.
• Enhance system security by adhering to contemporary security standards and protocols.
• Ensure future-proofing of core applications through technological upgrades.
• Achieve measurable reductions in application maintenance effort (e.g., reduce man-hours from over 150 to fewer than 50 per application).
• Support the client’s ongoing growth and technological sustainability in a rapidly evolving industry.

• Migration of existing applications to Visual Basic .NET or equivalent supported frameworks.
• Implementation of security measures covering database access and software environment protections.
• Support for integration with existing data sources and external banking systems.
• Implementation of version control, testing, and deployment workflows aligned with Agile/Scrum methodologies.
• Comprehensive security auditing and compliance features.

• Core banking database systems
• Authentication and security systems
• External financial data providers

• Adherence to industry security standards to ensure data confidentiality and integrity.
• Reduction of application maintenance time from over 150 man-hours to fewer than 40-50 man-hours per application.
• System reliability and uptime to support critical banking operations.
• Scalable architecture to accommodate future growth and additional applications.

The modernization project aims to significantly improve operational efficiency by reducing application maintenance effort by approximately 70-75%. It will strengthen security posture, ensure compliance with supported technologies, and position the client for continued growth with a future-ready IT infrastructure, thereby supporting long-term stability and competitive advantage.
