I spent a couple of days trying to migrate a react app at v17 bootstrapped with create-react-app to v18 and Vite, but eventually gave up because all the tooling and libraries and deployment processes needed attention along that migration path. I'd be very surprised if 0.15 to 18.0 could be as seamless as you claim, for a real production application with hundreds of components and a few dozen dependencies
