Feel free to shoot me an email jason[at]thebestagency.com if you have anything specific. At a high level a lot of the components end up being pretty different because the UI is naturally pretty different. They share some functions but the "DOM" is mostly rewritten. But the redux actions and reducers are all pretty much the same (small changes depending on how to store state but that could definitely be abstracted away).

Are you using a monorepo? The reducers/actions are copied/pasted for each version? Thanks!
