Every organisation has systems it’s outgrown but can’t afford to replace — or so it seemed. Whether you’re stuck on ageing infrastructure with mounting operational costs, deep in technical debt after falling behind on upgrade cycles, or facing a full stack change from Ruby or .Net to a modern JavaScript architecture, the barriers to migration are no longer what they were. AI changes the economics completely.
Kyan’s approach uses your existing working codebase as the foundation. Our AI agents build a complete test suite, then systematically rewrite code line-by-line or function-by-function, testing the new version against the original at every step. The result is near-full automation of the migration process — with the confidence of continuous validation throughout.near-full automation of the entire process.

We start by building a comprehensive test suite from your existing codebase using AI agents, creating a safety net that covers the full behaviour of your current system before a single line of new code is written.In just 20 days at modest pricing, Kyan gives you proof of concept that acts as a base for further evolution.

Agents systematically rewrite your codebase to the target platform — function by function, module by module. Whether it’s a language migration, framework upgrade, or full stack change, the process is automated, structured, and auditable throughout.

The new version is continuously tested against the original product to ensure behavioural parity. Once validated, we support production rollout and handover, leaving your team with a modern, maintainable codebase they can confidently own.






We’re platform-agnostic and language-agnostic — we choose the best migration path for your specific system and goals.



As AI tooling evolves, so does our approach. We stay at the frontier of agentic development to ensure your migration benefits from the most capable, reliable automation available — and we also help teams add MCP (Model Context Protocol) architecture, so your newly migrated product is ready for AI integration from day one.
