Migrate Your COBOL Systems for a Faster, Agile & Future-Ready Enterprise
Upgrade Legacy COBOL Applications to a Digital Platform
10decoders help businesses to migrate and modernize the COBOL applications to cloud ready, API driven, high performance application with one of the cutting edge technology such as Java; .NET, microservices, and serverless architectures.
With our migration methodology driven by automation, we minimize manual work and speed delivery while keeping your business up and running. Our extensive experience with mainframe transformation projects ensures organizations can lower operational costs, increase maintainability and gain the agility required to meet the demands of digital innovation.
10decoders COBOL Migration Services
Bringing legacy applications to advanced levels, with architectural designs that are scalable over time in capability and ease of operability.
- 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 to bring us better performance, more flexibility and a great path forward.
-
Mainframe Offloading &
Cloud Modernization
Shift expensive COBOL workloads from active mainframes to a secure, scalable and cloud-native environment with less operational overhead and improved agility, cost effectiveness and utilization.
- API Enablement, Modularization & Integration Readiness
Break monolithic COBOL systems into into modular services and APIs that work well with ERPs, CRMs, digital apps and enterprise ecosystem.
- Modern UI Transformation & User Experience Revamp
Replace outdated green-screen or 3270 interfaces with modern, intuitive web and mobile experiences that enhance usability, productivity, and user adoption.
Handling Legacy COBOL Application Challenges
COBOL-reliant companies generally suffer from limitations that inhibit growth, innovation and operational agility.
Skill Gaps
The shrinking number of COBOL specialists makes updates slow, expensive and unviable.
High Mainframe Operating Costs
COBOL workload on aging mainframes is expensive. There are significant licensing, infrastructure, and maintenance costs associated with these older applications running virtualized workloads.

Limited Integration Capabilities
COBOL can’t easily plug into APIs, cloud services or more modern digital platforms.
Slow Development Cycles
Rigid, monolithic architectures decelerate change requests, preventing the product and innovation going to market.
Learn more
Outdated User Experience
Green-screen or terminal-based interfaces cause loss of productivity, greater learning requirements and inhibit user acceptance.

Scalability & Performance Constraints
As transaction volume increases, legacy applications hit performance walls and don’t have the flexibility that modern workloads require.
