We've migrated several projects to Preact with no issues at all. The projects depend on numerous React-based modules, including an extensive collection of components, some with state management, routing, data fetching, etc. They work seamlessly, built on either React or Preact. It only takes a small change in the build config, using babel-plugin-module-resolver to alias react and react-dom, to preact-compat.
