Migrate your COBOL for a
faster, agile enterprise.
Modernize legacy COBOL applications and eliminate the risk of manual intervention. 10decoders preserves your business logic while migrating to Java, .NET, cloud-native, and microservices architectures — with zero disruption.
Trusted by leading enterprises and healthcare teams
Upgrade legacy COBOL to a digital platform.
10decoders helps businesses migrate and modernize COBOL applications to cloud-ready, API-driven, high-performance architectures using cutting-edge technologies such as Java, .NET, microservices, and serverless platforms.
With our automation-driven migration methodology, we minimize manual work and speed delivery while keeping your business up and running. Our extensive experience with mainframe transformation ensures organizations can lower operational costs, increase maintainability, and gain the agility required to meet the demands of digital innovation.
Start your migrationBringing legacy COBOL to advanced levels.
Architectural designs that are scalable in capability and ease of operability — covering every phase from discovery through to cloud-native deployment.
End-to-End COBOL Assessment & Automated Migration
Complete discovery of COBOL code, dependencies, business rules, and data flows — followed by tool-automated translation into maintainable .NET or Java. Better performance, more flexibility, and a clear path forward from day one.
Mainframe Offloading & Cloud Modernization
Shift expensive COBOL workloads from aging mainframes to a secure, scalable, cloud-native environment. Dramatically less operational overhead, improved agility, better cost efficiency, and elastic utilization on demand.
API Enablement, Modularization & Integration Readiness
Break monolithic COBOL systems into modular services and REST APIs that integrate cleanly with ERPs, CRMs, digital apps, and the broader enterprise ecosystem — unlocking data and logic that's been locked in the mainframe for decades.
Modern UI Transformation & User Experience Revamp
Replace outdated green-screen and 3270 terminal interfaces with modern, intuitive web and mobile experiences. Dramatically enhanced usability, higher productivity, lower training burden, and far stronger user adoption across the enterprise.
The cost of staying on the mainframe.
COBOL-reliant companies face critical limitations that inhibit growth, innovation, and operational agility. Here's what's holding your enterprise back.
Skill Gaps
The shrinking number of COBOL specialists makes updates slow, expensive, and increasingly unviable. A retirement wave is taking critical institutional knowledge with it.
High Mainframe Operating Costs
COBOL workloads on aging mainframes are expensive. Licensing, infrastructure, and maintenance costs compound annually — diverting budget from innovation and growth.
Limited Integration Capabilities
COBOL can't easily plug into REST APIs, cloud services, or modern digital platforms — creating data silos and blocking digital transformation at the core.
Slow Development Cycles
Rigid, monolithic architectures decelerate every change request — preventing product innovation from reaching the market at the pace your competitors move.
Outdated User Experience
Green-screen and terminal-based interfaces cause productivity loss, steep learning curves, and weak user acceptance — a daily friction that compounds across your workforce.
Scalability & Performance Constraints
As transaction volume increases, legacy applications hit performance walls. They simply don't have the elasticity modern digital workloads require to scale on demand.
Turning legacy COBOL into performance-driven digital assets.
Automation, engineering excellence, and proven mainframe migration expertise — combined to deliver transformation that is fast, safe, and built to last.
Cost-Effective & Efficient
Reduce modernization costs with our automation-first frameworks, rigorous processes, and reusable Migration Accelerator. Definite Delivery methodology means predictable timelines and no surprise overruns.
Stable & High-Performing
We develop secure modern applications designed to support mission-critical transactions and deliver with reliability and consistency — no compromise on the robustness that made COBOL endure for 60+ years.
Scalable & Agile
Modernized systems are designed to scale, be more adaptable, and integrate more easily — enabling rapid development and a significantly faster time-to-market for every product change and new capability.
Enhanced User Experience
Provide your teams with easy-to-use, modern interfaces built for faster and more effective operations — minimizing training requirements and maximizing staff engagement from day one of go-live.
A proven path from mainframe to modern.
COBOL migration isn't a big-bang rewrite — it's a structured, phased journey. Here's how we de-risk every step and keep your business running throughout.
Discovery & Assessment
Full COBOL codebase audit — map dependencies, business rules, data flows, and JCL scripts. Produce a risk-ranked modernization roadmap.
Automated Translation
Run the Migration Accelerator to auto-translate COBOL to Java or .NET, preserving all business logic. Manual expert review for complex patterns.
Validation & Parallel Run
Functional equivalence testing and performance benchmarking in parallel with the live mainframe. No cutover until results match or exceed baseline.
Go-Live & Enablement
Phased cutover with rollback safeguards, team training, documentation, and continuous AI Ops to keep your modernized stack evolving.
