Moderniser du code existant complexe avec des agents IA.

Mistral successfully modernized a complex, 40,000-line Fortran 77 physics simulator for an energy company by migrating it to modern C++ using AI agents. A critical first step involved building a "parity harness" to verify that the new C++ code produced numerically identical results to the original, ensuring accuracy throughout the project. Before migration, AI agents were deployed to automatically document the legacy system by analyzing the code's structure and extracting information from old PDF files. The final, successful migration strategy involved a human-in-the-loop approach, guiding specialized AI agents for coding, testing, and reviewing to produce high-quality code and overcome complex challenges.
