Removing a “trusted” device
I have a company iPhone 6S that is my “trusted” phone and have just bought a private iPhone 8 as I am retiring and will return the iPhone 6S. Under settings, both phones are named. What happens if I remove the iPhone 6S? It took over two hours for the shop to set up my new phone using the iCloud and Apple ID of my old phone to transfer all the photos, contacts, etc., across and I am hoping that by removing the old device, I don’t lose all the data that transferred over......can you advise me please? Thanks, Graham
iPhone 8, iOS 11.2.6
