iBEAM COBOL to .NET Migration FAQs

Why should we move from COBOL to .NET now?

COBOL systems are expensive to maintain, talent is becoming scarce, and they can’t keep pace with today’s cloud, API, and AI-driven technologies. .NET offers a secure, scalable, and cloud-ready platform — and with iBEAM and GenAI, migration is faster, more accurate, and less disruptive than ever.

How does GenAI accelerate the migration process?

GenAI analyzes COBOL code patterns, automates the conversion of business logic into .NET structures, and optimizes for performance and maintainability. This reduces manual rework, improves accuracy, and speeds up delivery timelines while ensuring functional parity.

What is iBEAM, and how does it support our migration?

iBEAM is OptiSol’s proprietary modernization framework designed for COBOL-to-.NET transformation. It combines automated code conversion, phased migration strategies, and rigorous validation to ensure a smooth transition while preserving critical business logic and data integrity.​

Will there be any business disruption during migration?

With iBEAM’s phased approach and parallel validation environments, core banking and financial operations remain online during migration. This minimizes downtime, ensures customer transactions continue uninterrupted, and reduces operational risk.​

How long does a typical migration take?

Timelines vary depending on the size and complexity of your COBOL environment. Using iBEAM’s automation accelerators, smaller applications can be migrated in weeks, while large-scale enterprise systems typically transition in a few months with minimal disruption.
