Understand legacy code
SLIP – Reverse engineering – whitebox
SLIP, the Sysparency Legacy-Code Intelligence Platform, is the AI-supported analysis and documentation platform ReqPOOL consultants use in consulting projects. It reads the source code and existing documentation of a software system – regardless of technology, from SAP/ABAP through IBM mainframe with COBOL, PL/I and JCL, IBM i and NATURAL/ADABAS to open systems such as Java, Python, C/C++ and JavaScript – and produces a complete, source-proven system documentation, a queryable knowledge graph and transformation recommendations.
How it works
Ingest source code and documentation
SLIP analyses the entire code base together with existing documents – technology-independent, deterministic and reproducible.
Build the knowledge graph
Programs, data flows, interfaces, batches and data structures are linked into a queryable knowledge graph of the whole system.
Generate documentation
A navigable documentation application leads from business to technology: system dashboard → business and technical modules → individual software components down to the code. Every statement is provable down to program and line.
Ask questions and plan the transformation
The agentic AI assistant answers questions such as “What does this system do – and what breaks if I change it?” in seconds; transformation recommendations at system, module and component level are aligned with the project goal.
Core capabilities
Technology-independent analysis
SAP/ABAP, COBOL, PL/I, JCL, IBM i, NATURAL/ADABAS, Java, Python, C/C++, JavaScript and many more.
Source-proven system documentation
Every statement is provable down to program and line in the source code.
Queryable knowledge graph
Programs, data flows, interfaces, batches and data structures of the entire system.
Agentic AI assistant
Answers questions about behaviour, dependencies and change impact in seconds.
Transformation recommendations
At system, module and component level – aligned with further development, replacement or modernisation.
Navigable documentation application
From the system dashboard through modules to the individual component and code.
Value for the client
- Faster to reliable results: System analyses that take months manually are produced in days – consultants start with a complete, current view of the real system, not of outdated documents.
- Traceable instead of blackbox: Every statement in the documentation is backed by a source code reference – the analysis is deterministic and reproducible, every result verifiable.
- Knowledge stays with the client: Documentation, knowledge graph and assistant remain in the project as working tools – knowledge about the system no longer depends on individual heads.
- Well-founded decisions: Whether modernisation, replacement or continued operation – effort, dependencies and risks are assessed on facts from the actual code.
- Readable for AI agents: Legacy code becomes structured, queryable knowledge – the foundation that makes agentic delivery on existing systems possible at all.
- No licence costs: In ReqPOOL consulting projects clients pay no licence fees for the AI tools used – the platform is part of the consulting service.

Typical use cases
- Legacy modernisation and replacement: Fact base for tender, target architecture and migration planning.
- SAP custom code: Transparency over ABAP custom developments ahead of S/4HANA transformations.
- Mainframe analysis: Document COBOL, PL/I and NATURAL estates before the experts retire.
- Impact analyses: Which programs, data flows and interfaces does a change touch?

- EU hosting: The platform is operated entirely within the EU.
- Data never leaves the EU: All AI models are connected exclusively via EU data centres.
- The AI does not learn from your data: Client data and source code are never used to train AI models.
- Access protection: Role-based access and project-specific encryption keep client data strictly separated.
- No licence costs: The use of SLIP is part of the ReqPOOL consulting service.
Consulting with agentic AI: faster, traceable, EU-compliant.
