Most developers choose a Blazor component library at the start of a project and hope they made the right call. When they don’t, they often realize too late that switching frameworks is painful, risky, and easy to postpone. In this session, I’ll show how I migrated a production Blazor app to a new component framework in under 40 hours using AI. This was not a toy demo or a theoretical experiment, but a real-world migration where AI helped accelerate repetitive work while I stayed in control of quality, consistency, and architectural decisions. I’ll walk through how I prepared the project for AI-assisted migration, how I customized the AI with project-specific guidance, and how I used it throughout the process. Along the way, I’ll share what worked well, where the approach broke down, and when manual fixes and human judgment were still essential. This session is for developers who want to use AI for code modernization without blindly trusting it. You’ll leave with practical techniques, realistic expectations, and a repeatable approach you can apply to Blazor migrations and other refactoring projects.
