I have a new 15 Pro arriving Friday. I wonder if I should update the existing 12 Pro before doing the transfer to the new phone. My inclination is to NOT do that, in case there are any hiccups in the transfer.
Additionally, I’ll be taking a long day trip the next day, so I’m strongly tempted to not do anything with the new phone, or at least to not activate it on the cellular network.
I would generally recommend that you do update an old iPhone to the latest version of iOS before transferring to a new iPhone just in case Apple made any last-minute changes behind the scenes for old phones to improve the transfer process. But it’s probably not that important either way.
But I agree strongly that you should NOT switch to a new iPhone the day before taking a long day trip. That’s just asking for trouble. Make the switch when things can go wrong and they probably won’t. :-)
I’m actually considering NOT updating my 12 mini before the 15 arrives on Friday. If there’s any serious issues with 17.0, that 12 mini would allow me to go back to safe territory while Apple prepares a 17.0.1 or 17.1 fix. That 15 could just stay in its box for another couple of days while the fix is prepared. But if I update the 12 mini first, there will be no bridge back since Apple goes out of its way to prevent downgrades.
I’ll admit I’d be updating that 12 mini as @ace suggests if I had more faith in Apple’s software QA. But after the way certain more recent updates have gone (both macOS and iOS) with serious issues going unnoticed by both Apple and the entire “beta tester” community, such that Apple then had to pull updates or release emergency updates to the update, well, let’s just say I have lost faith to go all in with them. These days I always try having a fallback (or two).
My thought is that it does not matter. I have done restores from an older version of iOS to a newer, and it always worked perfectly fine. (That said, I generally upgrade my older phone first, but that’s mostly because I rarely get a new phone on launch day.)
As for taking a long trip the next day - again, it probably should not matter, but there have been weird issues in the past with brand new phones shortly after launch day with weird issues, so I’d say your temptation not to transfer until after you return from your trip is probably the best way, just in case.
What if you can’t update to the new iOS because the old phone (iPhone X) is unable to accept the iOS update? I will be receiving the new iPhone 15 sometime in October but hoping I won’t have transfer trouble.
It will work fine…just make sure that the X is up to date before doing the migration. Personally…I’ve always made a backup right before activating the new phone and then updating from that backup…IIRC there’s a way to have them both on wifi and do a direct phone to phone migration but I’ve never tried it and I might be misremembering things as it has been 5 years since we migrated phones. The fact that iOS 17 will likely be the last one our Xs models will get (along with the battery issues and better camera and faster processor) is one of the reasons we’re upgrading this year (well, that and also we just want to upgrade). I’m with Adam on this one.
The only glitch I’ve encountered is trying to activate the new phone’s SIM card (Verizon network) at the same time as trying to migrate an old phone to the new phone directly (using Bluetooth/Wi-Fi). It glitched and failed every time.
We “solved” the problem by setting up the new phone without migration, in order to get the SIM card properly activated. Then we backed up the old phone to iCloud, wiped the new one, and restored it from that iCloud backup. That worked.
As far as I know, this is what Verizon recommends for this. I have these instructions from back when I activated my 13 Pro a couple of years ago - which includes instructions on how to initiate the Quick Transfer / Migration after the activation. IIRC the instruction too have the old phone powered off (after disabling Find My) before starting the activation of the new phone was a key step.
Yeah, we saw that article. It was the transfer (at step 11) where everything glitched and failed. The SIM activation takes some time to complete, and stuff fails in creative ways if it hasn’t happened yet.
We had to skip all migration and let it boot up to normal operation with nothing but the default apps/configuration. Wait for the SIM to become fully operational (see the 5G icon, make a few test phone calls, etc.)
Then go back to system settings to wipe the phone. Then restore from the backup on the next reboot, which succeeded because the cellular network was fully functional at the start.
So, my iPhone 15 arrived about 90 minutes ago. Regarding the software update, I would do it differently if starting from scratch.
I responded to the initial prompt to migrate from my iPhone 14. I was hoping it would then notice that the software update was needed. However, it didn’t do that. It asked if I wanted to transfer the old phone number now. I refused, and after some delay, the new phone restarted. Now, it noticed that the Software update was needed and requested a connection to WiFi; once it found nearby WiFi, I selected my network; the iPhone connected without asking for the password, updated, and restarted. At this point, it again asked how I wanted to proceed, and I again went through the procedure to mate with my old phone. After responding to various prompts, including enabling my credit cards for Apple Pay, it transferred data for about 45 minutes and restarted. As I write this, the new phone is partially functional, as the actual app updates need to come from the cloud.
If I were to do this again, I would respond initially to set up the phone as new. I would run through any prompts with dummy information until I reached the software update required notice. I think I would need to supply the password for the WiFi network, but the whole process whould run faster as I would skip the initial handshaking between the two phones.
Got my 15 Pro Max yesterday afternoon and the transfer was… interesting. I just did it via wifi with the iCloud download of apps. Might have been a mistake.
After it started it prompted me to upgrade to 17.01, which I did. It took 20+ minutes to download and install, and then came back to the transfer setup screen. I used my old phone again to initiate the transfer a second time and then it worked. Initial was pretty quick, about 15 minutes, but then it took hours to download all my apps.
Biggest problem was that it couldn’t transfer my phone number. Sometimes it timed out instantly, but other times it said “Activating” and would err out after several minutes. I put this up to a slow-down of AT&T’s servers. I must have tried it 50+ times and it never worked. The weird thing is I finally tried to see if I could do other things on the phone while it was “Activating” and swiped up from the bottom. This seemed to mess up the “transfer phone number” screen because it went back to the cellular setup screen, but this time my old phone number wasn’t there. I had to enter it and my zip code manually. But then it worked instantly! Like less than 30 seconds it had transferred my esim to the new phone and I was up and running. So weird.
The next biggest problem I discovered was that the 1Password was not on my new phone. That made it tough to input my passwords into all my apps. I had to download 1P 8 on the new phone as 1P 7 is no longer on the App Store. Grrr. That was a hassle and I worried that the 8 database would cause problems with the 7 database all my other devices are still using. So far it seems to be just fine () – I changed a password on my Mac in 1P 7 and it changed it on the phone in 1P 8. But I suppose this means I’ll be forced to upgrade to 8 everyone at some point.
(I think if I’d migrated with a cable as Gruber had recommended, it would have transferred my 1P 7 app over and eliminated this problem. But naturally I didn’t have a Lightning to USB-C cable handy.)
Other than that, things seem to be working fairly well. I haven’t had time to try out the new phone much yet, not that it’s dramatically different. iOS 17 seems fine, though the new hiding of options in Messages, which sounded good, adds lots of steps for getting to your Memoji or even accessing Photos to send a photo and is quite annoying. (My fav new feature so far: the auto-deleting of one-time code text messages, of which I got a lot as about 20 apps insisted on sending me those to re-establish the app on the new phone.)
