Hi I need to transfer everything from my x over to my iPhone 11 when I receive it tomorrow so what’s the best way of doing this as don’t want to lose anything from my x. Also I will be selling the x on to a shop so I need to turn certain things off and wipe it again what needs turning off etc. Also I have a Apple Watch 4 how do I also go about linking it from my x to my iPhone 11. Any help would be really appreciated.
