What does it take to migrate a large-scale native app to React Native without rewriting everything from scratch?

In this webinar, engineers from Zalando and Callstack share how they approached React Native brownfield migration across a complex, multi-platform mobile architecture.

You’ll hear how Zalando’s internal Rendering Engine works with React Native, what made their component library cross-platform ready, and how they solved dev experience issues that block many teams. The session will also cover practical migration patterns and interop techniques developed in collaboration with Callstack during Zalando’s rollout.
