Mine the knowledge
AI extracts business rules, data flows, and dependencies from the legacy codebase into a queryable knowledge graph your engineers actually use.

Modernisation legacy avec copilotes IA, pas de réécriture big-bang
Sortez de COBOL, mainframe et Java vieillissant avec refactoring assisté par IA, génération de tests de régression et portes de gouvernance—livrez à chaque sprint.
The problem
The legacy stack runs the business—and blocks every change
-
COBOL and mainframe bottleneck delivery
Critical logic lives in code nobody under fifty understands. Every change becomes a multi-team coordination exercise, and new features queue behind the legacy team.
-
Knowledge retires with people
Documentation is patchy at best. As original authors leave, the safe answer to 'why this rule exists' is 'don't touch it'—and the modernization plan stalls.
-
Big-bang rewrites fail
Two-year rewrites lose sponsorship, miss the business reality that moves under them, and end as parallel systems neither team wants to own.
-
No audit trail on the current code
When auditors ask what the system actually does today, the answer is a person plus a debugger. Modernization without that lineage is a leap of faith.
Fonctionnement
Incremental refactoring with AI assistance and governance gates
Translate and refactor
Governed prompts translate legacy modules into target stacks; regression tests are generated from observed behavior, not from imagined specs.
Ship and govern
Incremental cutover by capability with rollback, audit trail of every AI-generated change, and CISO-ready evidence of human review.
Flow adapts to your target stack, regulatory context, and team velocity.

Ce qui est inclus
Everything you needto modernize without the freeze
Code mining, AI-assisted translation, governance gates, and audit trail in a single layer—delivered with your engineering team owning the rollout cadence.
Code knowledge mining
Business rules, data flows, and dependencies extracted into a queryable graph engineers can search and trust.
AI-assisted translation
Governed prompts translate modules into the target stack, with human review gates and policy enforcement.
Incremental refactoring
Capability-by-capability cutover with feature flags, rollback, and parallel-run validation.
Regression test generation
Tests synthesized from observed legacy behavior—not from incomplete specs—so cutover risk is measurable.
Governance gates
Security, IP, and compliance review built into the AI workflow; no ungoverned co-pilot sprawl.
Documentation generation
Up-to-date docs are a byproduct of the migration, not a side project that ages out of date.
