If you intend the English version to always be a “clone” of the other one, perhaps you might consider an extension for a multilingual site instead?
Personally, I’m using Qtranslate X, but I believe support is slowly fading.
WPML (commercial software) is one of the best known. I often see recommendations for Polylang (there are both free and paid versions).

With this approach, you’ll hopefully get much less headache from maintaining two “parallel universes”.
