iphones is all the apple I go for. Within the household I have probably done 8 or so device migrations, and they have always been seamless. Some bad luck there.iPhone 14 Pro for the better 1/2 last night. Updating from an 11. moved the SIM, plugged it in and followed the awesome Apple auto-migrate process that started immediately. It downloaded a 3+GB update from the iStore and once it finished the D/L it said it was installing and transferring data/apps/settings but... Nah, it just sat there hung. erased and will try again tonight.
I own no Apple products aside from an Apple TV sub lol. Wish I could talk her into an Android, but the daughter units have iPhones and iMessaging seems to be of utter importance.
