Many businesses still operate on outdated legacy COBOL systems, which have become simultaneously more complex, costly, and less agile. These COBOL-powered systems present many challenges and risks, significantly depleting the overall corporate IT asset value.

Application modernization can be limited to areas where effective, a pragmatic solution as COBOL’s complex applications can be difficult to be wholly renewed and replaced. A methodical understanding of a company’s current system before formulating a modernization strategy is crucial. By minimizing operational disruption through modernizing existing systems in stages, NRI’s Legacy Lift Lab (LLL) framework allows clients to continue servicing customers while running critical operations.

Large, complex legacy systems powered by COBOL tend to present many challenges, significantly depleting the value of corporate IT assets. NRI meticulously plans and modernizes large, complex systems, including risk-managed, phased migration plans, ensuring the operation of current systems. We enable effective migration and modernization strategies by thoroughly analyzing and understanding complex, black-boxed system specifications:

1. Legacy System Analysis & Modernization Strategic Planning:

By deeply understanding system characteristics and priorities using the latest generative AI-assisted techniques, NRI creates phased modernization strategies that minimize risk while maintaining service continuity.

2. Modernization Plan Execution:

NRI QMS, our specialized quality management framework, is fortified by our extensive experience in the financial services industry. We enhance quality by leveraging proprietary tools tailored to project characteristics. For example, by developing thousands of screens using these tools, we ensure consistency and uphold the highest standards.

3. Testing and Migration:

By conducting tests defined in NRI's standard development framework, including current-to-new comparison tests, NRI can enhance quality in both functional and non-functional aspects.

With a team of over one thousand seasoned COBOL engineers, NRI offers unparalleled resources for stable COBOL system maintenance, continuous enhancement, and cloud migration. Drawing from our large resource pool, NRI addresses legacy infrastructure and cloud migration challenges as well as other top mainframe modernization priorities, including improved security, cloud as a strategy, software and hardware cost reduction, improved API integration, and cross-organizational technology consolidation. We provide concise system content understanding to ensure that collective and continuous changes can be made to core legacy systems.

NRI’s precise current system analyses include vetted expertise in visualizing complex and large systems, in-depth analysis covering business rules and user requirements, and automated, time-efficient AI-based analysis. NRI’s reliable migration results from our team’s extensive large-scale cloud migration project knowledge, our skilled engineers’ modern and legacy technology proficiency, and our concise approach to risk-managed, phased migration planning.

NRI’s high-level quality assurance minimizes operational disruption by systematically modernizing existing systems with highly reliable, automated testing methods and tools, and by building systems with high processing performance based on cloud infrastructure and middleware expertise.

NRI Legacy Lift Lab addresses and solves critical issues by focusing on legacy systems’ core values, conducting precise analyses, and implementing effective modernization strategies. Our migration approach doesn’t just transfer systems: NRI boosts IT asset value and guides businesses toward future innovation.
