Just a quick question really: My Apple Watch is currently being used with my iPhone 6 however, I am expecting my iPhone 7 to arrive this week. What is the correct process to switch to the 7? Do I just back up my 6 to iCloud, and then restore from the back up, when on the iPhone 7? Will this also restore the data between my Apple Watch and my iPhone 6 (i.e. watch faces, health stuff, aps, etc) or is it better to go through the 'Unpair Apple Watch' process (via the Apple Watch app on my iPhone 6) and then just pair it to my iPhone 7?
