I was planning to rewrite an existing IOS app using react native. The existing IOS app is already published in the APP store.
I would like to know if it is possible to completely create a new build and release the new react native app to the app store ? My guess was to just change the bundle identifier of react native app to the one on the existing App to get released. But not sure if it is the right way.
Also if we publish, can we test it before it is released to users or will it immediately reflect ?
The alternate idea would be to create a new app and redirect them to the new app. This is even possible ?
