| Abstract (ENG): |
Modernizing legacy systems is an ongoing research
topic, driven by the need to ensure and maintain
mission-critical operations while overcoming complex,
outdated architectures. Challenges include large tech-
nical debt, and the inefficiency of traditional manual
migration processes at scale. In this work, we pro-
pose that the synergy between structured, rule-based
knowledge extraction and Retrieval Augmented Gen-
eration (RAG)-driven generation provides a system-
atic framework for maintaining functional integrity
throughout the modernization process. Our results
show that the highest degree of functional integrity is
achieved, when use-case-specific context from a knowl-
edge graph is integrated into the generative process,
effectively preserving complex business logic while
minimizing artificial intelligence (AI) hallucinations. |
