Application transformation

COBOL to Python migration with functional traceability

We transform structures, processes, and business rules into an understandable, testable Python codebase ready to integrate with current architectures.

View the process

More than syntax translation

A reliable migration must interpret control flows, data access, batch processing, formats, and integrations. The goal is to preserve required behavior and make transformation decisions explicit.

COBOL analysis

Identification of modules, calls, copybooks, files, data, and entry points.

Python design

Mapping into clear modules and components with defined boundaries and testable responsibilities.

Verification

Comparison of results and scenarios to detect differences before transition.

Migration principles

Traceability: connect source elements, target elements, and transformed rules.
Equivalence: validate relevant outputs and effects with representative cases.
Readability: produce Python code that teams can maintain and evolve.
Transition: plan coexistence, deployment, and reversibility where needed.
