Modernization Division

Legacy Code Modernization

Give new life to old systems. We migrate COBOL, FORTRAN and legacy applications to modern technologies.

Legacy Code Modernization

COBOL Migration

Transformation of mainframe systems to Java, .NET or modern microservices.

FORTRAN to Python

Modernization of scientific code preserving critical business logic.

Legacy Maintenance

Support and incremental improvements on systems that can't be migrated yet.

Integration APIs

We expose legacy functionality as modern APIs for new applications.

Reverse Documentation

We document undocumented systems to facilitate future migrations.

Legacy Testing

We create test suites for code without coverage before modifying.

Our Process

How we work to guarantee your project's success

1

Code Archaeology

Deep system analysis: dependencies, flows, hidden business logic.

2

Migration Strategy

We define approach: strangler fig, big bang, or hybrid based on risk.

3

Abstraction Layer

We create interfaces that allow coexistence of legacy and new code.

4

Incremental Migration

We move functionality module by module with continuous validation.

5

Decommission

We retire legacy system only when new system is 100% validated.

Technologies We Use

Specialized tech stack for this service

COBOL
FORTRAN
Java
.NET

Use Cases

Real scenarios where we apply this solution

Caso #1

The Problem

Bank with 30-year-old COBOL core banking, impossible to hire maintainers.

SC

Our Solution

Progressive migration to Java microservices with strangler fig pattern.

The Result

50% of system migrated in 18 months, new features 10x faster.

Caso #2

The Problem

Manufacturing company with FORTRAN system for engineering calculations.

SC

Our Solution

Rewrite in Python with NumPy preserving numerical precision and exhaustive validation.

The Result

Maintainable code, integration with modern tools, 5x faster.
