How to Use AI to Modernize Legacy Code — Complete Guide (GenAI + Refactoring Pipelines)

Stop drowning in legacy code. In this video, I'll show you exactly how to use Generative AI tools (GitHub Copilot, Claude, OpenRewrite) to modernize old codebases and build automated refactoring pipelines — even if you've never done AI-assisted refactoring before.
This is the full overview. Deep-dive videos for each topic are linked below.
