How to Set Up a New iPhone and Move Everything From the Old One

The box is open, the new iPhone is charged, and somewhere in the back of your mind is the memory of the last upgrade, when “moving everything across” turned into an evening of re-downloading apps, re-logging into your bank, and discovering at the worst moment that your two-factor codes were stranded on a phone you’d already wiped. It doesn’t have to go like that. The transfer itself is genuinely good now — most of your life slides across in under an hour with almost no input from you. The trouble is always the same short list of things the automatic process politely declines to handle, and knowing them in advance is the entire difference between a smooth swap and a ruined evening.

Before you touch the new phone at all, do three things on the old one. Update it to the latest iOS, so the two phones speak the same language. Make a fresh backup (Settings → your name → iCloud → iCloud Backup → Back Up Now) as a safety net even if you plan to transfer directly. And make sure you actually know your Apple Account password and your phone passcode — you’ll be asked for both, and “I’ll remember it” has stranded more people on setup screens than any technical fault.

Quick Start does the heavy lifting

Power on the new iPhone and hold it next to the old one. Within seconds the old phone offers Quick Start, an animation swirls onto the new screen, you point the old camera at it, and the two devices pair. This carries your Apple Account and most of your preferences across automatically, and it’s the moment everything good begins. From here you reach the one genuinely important fork in the whole process: how the bulk of your data actually travels.

Direct transfer versus iCloud: pick the right one

This is the choice people get wrong, usually by defaulting to whatever the screen suggests first. They are genuinely different, and the right answer depends entirely on whether the old phone is in your hand.

Direct transfer moves data straight from one phone to the other, including app data that an iCloud backup sometimes skips, and it doesn’t care how much iCloud storage you have. Keep both phones plugged in and close together, and if you have the right cable to link them directly, use it — wired is dramatically faster than doing it over Wi-Fi, and it spares you the airborne stalls. iCloud restore is the answer when the old phone is already gone — sold, traded, or lost — and it leans entirely on that backup you hopefully made. Apps re-download from the App Store in the background afterwards, so the phone looks done before it actually is; let it sit on Wi-Fi and charge for an hour before you judge it.

The eSIM is the bit that traps people

Here is where a smooth transfer suddenly stalls. Almost every iPhone now uses an eSIM rather than a physical card you can pop out and slot into the new phone, which means your actual phone number has to be migrated as data, and that step is separate from everything above.

The good news is that eSIM Quick Transfer often handles it during setup — the new phone offers to bring your number across, you confirm, and it works over the air in a couple of minutes. When it doesn’t offer, or your carrier isn’t part of the automatic system, the path is Settings → Cellular → Set Up Cellular (or Add eSIM) on the new phone, and from there you either transfer from the nearby old phone or scan a QR code the carrier provides. Some networks still make you ring them or tap through their app. Whatever you do, do not factory-reset or recycle the old phone until you’ve confirmed the new one has signal and can make a call — a wiped eSIM is a genuine hassle to recover, and “I’ll sort the SIM later” is how people end up phoneless on a Monday morning.

The apps that always need a manual nudge

The transfer moves your apps and most of their data, but a specific handful guard their data so carefully that they need you to step in. Knowing them beforehand turns a panic into a checklist.

• Authenticator apps. If you use Google Authenticator or similar for two-factor codes, those codes may not ride along automatically. Check whether yours offers cloud sync and turn it on before you wipe the old phone. Better still, codes stored in Apple’s own Passwords app travel with your account without any drama.
• WhatsApp and Signal. Encrypted messengers keep their chat history in their own backups, not the iPhone’s. Trigger an in-app chat backup on the old phone first, or use WhatsApp’s built-in transfer, or you’ll arrive with a blank history.
• Banking and payment apps. Many re-verify your identity on a new device as a security measure. Have your card and your banking login handy; it’s friction by design, not a fault.
• Health and Home data. Your Health history and Home setup only transfer if your iCloud backup is encrypted (it is, by default, but worth confirming) or you used direct transfer. Lose this and there’s no second chance at years of step counts.
• Loyalty cards and tickets in Wallet. Most travel passes, event tickets, and store cards move across with your account, but a few stubborn ones — gym passes, certain transit cards tied to the physical chip — need re-adding by hand. Check Wallet before you bin the old phone, especially if a concert or a flight is coming up.

The pattern across all of these is the same: anything that protects money, identity, or an encrypted history treats a new device as a stranger until you prove otherwise. That’s the system working as intended, not failing you. Budget ten quiet minutes at the end to walk through each guarded app once, rather than discovering the gap at the till or the gate.

Passwords and passkeys: the quiet success story

The part that used to cause the most pain is now the smoothest. Your saved logins live in the Passwords app and sync through your Apple Account, so the moment you sign in on the new phone, every password and passkey you’ve saved is simply there. There’s nothing to export, nothing to import, nothing to lose. When an app asks you to log in again after the move, tap the password field and the right credentials are offered straight away. It’s the one piece of the migration that genuinely just works, and after years of it being the worst part, that still feels slightly miraculous.

One last housekeeping job people forget: if you wear an Apple Watch, it follows the iPhone automatically during the transfer, so don’t unpair it manually — doing so just creates work. And keep the old phone, untouched and un-wiped, for a week. Only once you’re certain everything made it across — the photos, the number, the codes, the bank app — should you erase it with Settings → General → Transfer or Reset iPhone → Erase All Content and Settings.

The honest truth about iPhone migration in 2026 is that Apple has automated roughly ninety percent of it into something your least technical relative could manage, and then left the final ten percent — the eSIM, the authenticator codes, the encrypted health history — exactly as fiddly as it ever was. That gap is where every bad upgrade story comes from. Walk through the checklist above, resist the urge to wipe the old phone the moment the new one lights up, and the swap becomes what it should be: an hour of waiting, a coffee, and a new phone that feels precisely like the old one, only faster.
