Chat migration is now possible according to WhatsApp FAQs. And it doesn’t involve the cloud (makes sense due to encryption). They are all local transfer between the two phones.Instead shouldn't watsapp bring out native data migration between Android Google cloud and ios icloud ?
Android to iOS seems the easiest as it just requires iOS 15.5 and move to iOS app on Android.
iOS to Android seems sketchy as WhatsApp support still stated that it’s only between iOS and a Samsung phone with Android 12 using Samsung smart switch. Google said any new phone with Android 12 should be able to do so, but never provided any more details on how.
I have not really seems any testimonials about both processes though.
