Teaching an AI agent to upgrade .NET, React, and Next.js apps for real — not just talk about it
Every engineering team has that repo. The one running a framework version from three or four years ago. Everyone knows it needs an upgrade. Nobody wants to be the one who breaks production doing it.
That's the problem UpgradePilot — an open-source, multi-agent upgrade pipeline — is built to solve.
