Here's How Apple's New iPhone to iPhone Data Migration Feature Works in iOS 12.4

Apple this week released iOS 12.4, the newest version of iOS 12 available for iPhones and iPads. One of the new features in iOS 12.4 is an updated data migration option that uses device to device transfers rather than relying on iCloud.

Apple didn't provide much information on the new data migration feature, so we thought we'd check it out in our latest YouTube video.


Setting up an iPhone using the new options uses the same Quick Start process that's been in place since iOS 11. When you get a new iPhone, you simply need to hold your existing iPhone nearby to initiate the setup process on the new device.

Quick Start confirms your Apple ID and then uses the camera to pair the two devices to one another by scanning an animation. After the pairing process completes (which includes the setup of Touch ID and Face ID), you'll see the new "Transfer from iPhone" option.

Transferring from iPhone, as the name suggests, bypasses ‌iCloud‌ and migrates data from one iPhone to another in a device to device capacity, which means it's done offline.

Prior to Apple's introduction of this feature, Quick Start only offered a "Download from ‌iCloud‌" option which required an ‌iCloud‌ backup.

The new iPhone to iPhone option is a useful way to transfer data for those who only have 5GB of free Apple storage, as there's not always enough room to create an ‌iCloud‌ backup. It's also useful when Wi-Fi connection speeds are limited, and it will ultimately make it quicker to get a new iPhone up and running.

It works similarly to an ‌iCloud‌ backup or an iTunes backup, transferring over information like photos, app information, device preferences and settings, and more. App data is transferred over, but as with an ‌iCloud‌ backup, apps are downloaded directly from the App Store rather than from your existing iPhone.

The amount of time that it takes to transfer data from one iPhone to another will vary based on what's on the existing iPhone, but Apple provides a data transfer estimate on the main data transfer screen.

Using this method, it's faster to get photos, music, and other media from one iPhone to another because there's no longer a need to wait for that content to download from ‌iCloud‌.

The new iPhone to iPhone data transfer process requires both devices to be running the release version of iOS 12.4 or later, and it won't work on devices running earlier versions of iOS 12.

iPhone to iPhone data transfers can be done over Wi-Fi, but there's also an option to transfer data using a wired connection by utilizing a USB3 Camera Adapter and a Lightning cable.

So is this going to speed up that process compared to download from the Cloud?

I've alway started fresh! Clean slate to avoid cruft/unwanted random code. It can be a pain when bringing the phone back to normal use, but I feel its worth it!
What is “random code”? You a windows user by any chance? There is no “cruft”. You have iOS and then apps. Apps run in their container. There is nothing more to it. There is literally no difference between you setting up a device as new and installing and downloading your old things to it or doing a full device restore.

This is just me, but, I always start fresh (except for contacts/calendar/notes/reminders) when I get a new phone. :)

The only thing "new" in this process is that it no longer works with iOS 11 and has the option for connecting the devices by cable.

Used this method 3 wks ago to setup new iPP 11. The iPP came with 12.3.1 and I setup from by XR with had 13 b2. The pairing notifications said that both devices need iOS 11 or later. Setup was all wireless.

You are absolutely correct. It is much more sophisticated than a QR code.
If I understand it correctly the method used with iOS 11 and later is called Quick Start but requires an iCloud backup. This new method seems to be a variation on Quick Start that doesn’t need an iCloud backup. It transfers the data directly between the devices. So, it is completely new.

QR codes lol. Apple fail.
"the two devices to one another by scanning an animation" It doesn't use QR codes. It's quite more complicated than a QR. Like when an :apple:watch pairs with a phone. Kind of a sparkly thing. Very complex.

I may do that with my next phone, just to get rid of the cruft built up over time.

I've been restoring backups to upgrade my phone since my first iPhone (4) in 2010. Nine years of cruft! What's amazing is that everything still works smoothly.
