I know this has not much to do with the post but when transferring over make sure your iMessages among other iCloud data are synced to the proper email before transferring over. When I got my new phone last month my phone didn’t tell me iMessage wasn’t synced till it was already wiping it and by then it was too late. So when my phone “fully” transferred everything over I had about 2 weeks of messages saved and everything else was gone. Luckily I backed my phone up the day before on my computer just in case something liked that happened.
