Kiro packages repeatable php-to-java migration workflow as skill files and integrates with AWS Transform

The post describes a reproducible PHP-to-Java migration 'engine' built as versioned Kiro skill files (php-to-java-migration and php-model-discovery) that run an eight-phase, parity-first workflow inside a .kiro workspace. It also notes a native integration so AWS Transform can run the same skill-driven pipeline agentically at portfolio scale while Kiro supports interactive, single-app runs.

Mistral uses AI agents to migrate 40k lines of Fortran 77 reservoir simulator to C++

Mistral migrated a physics‑intensive reservoir simulator—about 40,000 lines of Fortran 77—into C++ by building a numerical parity harness, using AI agents (via Vibe CLI and Mistral OCR) to document and translate components, and combining structured agent workflows with human review. Key lessons: prioritize numerical agreement checkpoints, reconcile scattered documentation before refactors, and balance agent autonomy with human oversight to ensure maintainable, verifiable results.
