Legacy System Documentation
Code Archaeology & Knowledge Transfer
Code Archaeology - Extract knowledge from undocumented legacy codebases
Architecture Diagrams - Visual maps of system structure and data flows
Knowledge Transfer - Interactive workshops for team onboarding
Living Documentation - Docs that evolve with your codebase
Professional reverse engineering of legacy PHP systems to uncover hidden business logic and architectural patterns. We trace code execution paths, map dependencies, and document undocumented features through systematic testing and analysis. This formal software archaeology discipline combines source code analysis with behaviour testing to rebuild missing system knowledge, protecting your organisation from key person dependency risks.

Our Documentation Process
From Code to Clarity
System Discovery
Deep dive into codebase structure, database schema, configuration files, and deployment processes. Map dependencies and integration points.
Behaviour Analysis
Trace code execution paths, identify critical business logic, document edge cases and undocumented features discovered through testing.
Visual Architecture
Create architecture diagrams, data flow diagrams, entity-relationship diagrams, and deployment topology visualisations.
Documentation Writing
Technical documentation for developers, operational runbooks for support teams, and high-level overviews for stakeholders.
Interactive Workshops
Guided walkthroughs with your team, Q&A sessions on complex areas, hands-on exploration of critical paths and edge cases.
Ongoing Maintenance
Documentation-as-code practices, automated diagram generation, continuous updates as system evolves, AI-assisted maintenance.

Why Document Legacy Systems?
Business Benefits
Risk Reduction & Business Continuity
70% reduction in production incidents
Understand what code does before modifying it. Protect against key person dependency and reduce costly bugs from undocumented dependencies.
Accelerated Team Productivity
50% faster developer onboarding
New developers productive in weeks, not months. Support teams troubleshoot independently without constant escalation to senior developers.
Faster Modernisation & Migration
30% faster migration planning
Clear documentation of current state makes modernisation planning faster and more accurate. Identify what can be replaced versus rewritten.
Strategic Decision Making
Clear ROI for technical initiatives
Stakeholders understand system constraints and costs. Make informed decisions about technical debt and investment priorities with clear ROI data.
