AI-powered legacy modernization to ODA

URN M25.0.780

Topics AI (Artificial Intelligence), Cloud migration, IT Transformation

Introducing a GenAI-powered smart factory model that transforms legacy telecom systems into Open Digital Architecture-compliant, cloud-native microservices.

Project companies

The Open Digital Architecture (ODA) offers a clear path to modernization, but achieving compliance at scale remains a complex challenge—especially for CSPs navigating legacy estates. These environments are often monolithic, outdated, and poorly documented—limiting agility and increasing operational costs. This Catalyst introduces a genAI-powered transformation model that modernizes legacy applications into cloud-native microservices mapped to the ODA framework. The solution provides a step-by-step smart factory approach. First, genAI extracts business logic from legacy codebases. Then, it redesigns applications into modular, ODA-compliant components. Next, the system generates forward engineering artefacts, including Open API definitions, service designs, and test cases. Finally, it supports cloud-native deployment using TM Forum’s Open Digital Framework (ODF). By automating key phases of the modernization lifecycle, the Catalyst reduces manual effort and accelerates delivery. GenAI bridges knowledge gaps by interpreting legacy logic that lacks documentation, and it continuously improves through pattern recognition. This allows CSPs to modernize at scale while improving accuracy and consistency. In addition, the Catalyst helps evolve the ODA component model itself. It maps newly generated microservices and APIs to the latest TM Forum standards. It then feeds insights back into the ODA catalog and supporting broader industry adoption. The approach can create operational efficiency, faster transformation, and stronger compliance. CSPs can decommission legacy systems, adopt new technologies faster, and reduce technical debt. They also improve governance and scalability by aligning modernization with open standards. True success lies in turning complexity into clarity. This Catalyst aims to extract deep business logic from legacy systems, accelerate re-architecture with minimal rework, and produce deployable, standards-aligned microservices—automatically. With a smart, AI-led factory model, it reimagines transformation not as a one-off challenge, but as a scalable, sustainable engine for agility and innovation.
