What is AI-Powered Legacy Modernization?

AI-powered legacy modernization uses advanced machine learning to automatically analyze, translate, and refactor legacy code into modern languages and architectures. It reduces modernization time from years to months while preserving business logic and improving code quality.

Logic Preservation

How Does AI Modernize Legacy Systems?

Intelligent automation from code analysis to production deployment

Automated Code Translation

AI translates COBOL, PL/I, RPG, and other legacy languages to modern Java, C#, Python, or Go. Preserves business logic with 99.9% accuracy while generating idiomatic, maintainable code.

  • Multi-language translation (COBOL, PL/I, RPG)
  • Business logic preservation
  • Idiomatic code generation

Intelligent Refactoring

Goes beyond translation to modernize code structure. AI identifies anti-patterns, applies SOLID principles, and refactors monolithic code into maintainable, testable modules.

  • Anti-pattern detection
  • SOLID principles application
  • Modular architecture design

Database Modernization

Automatically migrates from DB2, IMS, VSAM to modern databases. AI generates schema translations, data migration scripts, and ORM mappings while preserving referential integrity.

  • Schema translation automation
  • Data migration with validation
  • ORM mapping generation

API Generation & Integration

AI automatically wraps legacy business logic in modern REST/GraphQL APIs and generates integration code for cloud services, enabling gradual strangler-fig migration patterns.

  • REST/GraphQL API generation
  • Cloud service integration
  • Strangler-fig support

Automated Testing Generation

AI generates comprehensive unit, integration, and regression tests by analyzing legacy code behavior. Achieves 85%+ code coverage automatically, ensuring migration accuracy.

  • Behavioral test generation
  • 85%+ code coverage
  • Regression validation

Incremental Migration Planning

AI analyzes dependencies and generates phased migration plans that minimize risk. Enables parallel running of legacy and modern systems during transition.

  • Dependency analysis
  • Risk-based prioritization
  • Parallel execution support

Frequently Asked Questions

Can AI really translate COBOL code accurately?

Yes. CogniX.AI achieves 99.9% business logic preservation by training on millions of lines of COBOL code and using semantic analysis to understand business intent, not just syntax. We validate translations with automated regression testing.

How much faster is AI modernization vs manual rewrite?

AI modernization is 4-5x faster than manual rewrites. A typical 1M-line COBOL system takes 18-24 months with AI vs 5-7 years manually. AI also reduces risk by preserving existing business logic rather than reimplementing from scratch.

What happens to my mainframe database?

AI automatically migrates DB2, IMS, and VSAM databases to modern platforms (PostgreSQL, Oracle, SQL Server). We generate schema translations, data migration scripts, and validation tests. You can run parallel for validation before cutover.

Can I modernize gradually instead of big-bang migration?

Yes. CogniX.AI supports strangler-fig patterns where we wrap legacy components with APIs and gradually replace them. AI analyzes dependencies to create risk-minimized migration phases that enable parallel running.

What about undocumented business logic in legacy code?

AI excels at discovering undocumented logic by analyzing code behavior, data flows, and execution patterns. We generate comprehensive documentation and tests for the modernized code, making it maintainable for future developers.
