This is a really cool engineering article on how they managed the migration of React 16 rewrite.

It illustrates the use of

- feature toggles to reduce merge conflicts

- TDD for api coverage

- regression logging for faster feedback loop

- coverage chart for motivation

- staggered rollout and A/B testing with an eye on product metrics for migration issues

Thanks for sharing!
