This migration was really slick. We just ran it on the files we needed migrated (you can’t just pass files as args to the executable, you’ve got to pipe the names in)

find src -name "*.re" | yarn Upgrade 
Or echo src/front/components/InstructionsComponent.re | yarn Upgrade 

And then install the compat library and add it to the bsconfig.json.
yarn add reason-react-compat 

In one instance we had to remove an unnecessary function call to React.Children.whatever that the compiler was failing on.
