Legacy Code Understanding
COBOL, Fortran, PL/SQL, RPG, and more. Clark doesn't just parse syntax. It reconstructs the business logic buried inside decades of accumulated code.

Code Modernization
Decades of COBOL, Fortran, or PL/SQL don't have to slow you down. Clark understands what your code does, not just what it says.

Modernisation
Move legacy systems forward
Clark reads decades-old codebases, maps their behaviour, and rewrites them into maintainable modern stacks, without losing the logic that runs your business.

Capabilities
Modernisation Intelligence
Automated Documentation
Generate comprehensive, accurate documentation for codebases that have none. Every module, every function, every data flow, explained in plain language for your team.
Incremental Migration
Safe, tested migration paths that don't break production. Clark migrates module by module, validating behaviour at each step before advancing. No big-bang rewrites.
Test Generation
Create comprehensive test suites for legacy code before touching a single line. Behaviour is captured, codified, and enforced throughout the migration journey.
Architecture Analysis
Surface hidden dependencies, undocumented integrations, and embedded business logic across your entire codebase, visualised, mapped, and ready for planning.
Risk Assessment
Flag high-risk migration paths before touching code. Clark ranks modules by complexity, coupling, and historical defect density, so your team starts where it matters most.
Use Cases
Modernisation in Practice
Banking
Banking Core Modernisation
A public sector bank's mainframe COBOL core, 30 years old and growing. Clark documents every transaction path, generates a migration roadmap, and validates equivalence at every step, without a single day of downtime.
Government
Government System Migration
Ministry applications written in languages no longer taught. Clark reverse-engineers the business logic, creates modern equivalents, and ensures citizen-facing services remain uninterrupted throughout.
Manufacturing
Manufacturing ERP Modernisation
Decades of customised SAP logic embedded in ABAP that nobody fully understands. Clark maps every custom object, documents every business rule, and guides a safe migration to modern architecture.
Powered by Clark
Semantic Understanding, Not Pattern Matching
Other tools treat legacy code as text to translate. Clark treats it as a specification of behaviour to understand. Its deep reasoning capabilities let it reconstruct intent, the why behind the what, even when that intent was never documented.
This means Clark can detect when a literal translation would produce subtly wrong behaviour, propose a semantically equivalent but architecturally sound alternative, and explain the difference to your team in plain language.
