Fusion42 · 9 September 2026 · Fusion42 review

Mistral assisted a European energy operator with migrating a complex legacy Fortran 77 codebase to modern C++ using AI agents, achieving numerical parity and improved code structure through autonomous documentation and incremental migration strategies.

This Wire brief sits within Fusion42's coverage of Deep Tech: Telecom & Connectivity.

◆ ◆ The Wire takeaway

You can now automate complex legacy scientific code migrations with AI agents that verify numerical parity and handle documentation, cutting migration risks and accelerating modernization. Start integrating AI tooling to replace procedural legacy with modern object-oriented code while maintaining output accuracy.
