android to ios is simple n straightforward,i retain all of my data,doing it many times already...unlike ios to android,my experience is horrible especially whatsapp data,i lost years of chat backup twice,once during 2016 and recently last year when i opt to change my 13 pro to android,i lost whatsapp chat from 2017 until sept 2022...personal chat is ok but since i'm using same number for customer,all details lost just like that.
