I’ve bought an iPhone 13 Pro and need to transfer data from my iPhone 7. I used Quick Start to do data migration but it keeps failing. The error message is Unable to Complete Data Transfer iPhone. I would like to listen to some advice to fix this issue or other ways to transfer iPhone data.
- Question from Apple Community
It is a great pleasure for an Apple fan to unbox a brand-new iPhone. You must not want to suddenly switch to an empty iPhone, so you need to transfer data from old iPhone to new iPhone.
After iOS 12.4, users could directly import settings and data to another iPhone by Quick Start. Most of the time, this feature works perfectly, but iOS is not perfect.
You might have problems transferring iPhone data with Quick Start. Follow the next section to know how to fix it.
As we mentioned above, Quick Start works on an iPhone running with iOS 12.4 or later version. If your iPhone is still running with old iOS version and can’t see the option Transfer from iPhone, you need to update the target iPhone to iOS 12.4 or later. iOS 11 just support migrating iPhone settings. Follow the steps to update the system.
1. Go to "Settings" on your iPhone, and tap "General".
2. Tap "Software Update". If there is any newer iOS version, follow the guide to update it.
If you could not see the prompt on the source iPhone, there might be system bugs on the source iPhone preventing it from answering the calls of iPhone migration. Restarting iPhone will refresh the system.
If you are using iPhone X, 11, 12, 13, press and hold either volume button and the side button until the power off slider appears.
For iPhone SE, 8, 7, 6, press and hold the side button until you see the slider turn off.
If the source iPhone is brand-new and has not been activated, you need to insert SIM card into it. iPhone cannot be activated without a SIM card.
The power supply should be stable to do wireless data transfer. Users reported that they could complete data transfer after connect the old iPhone and new iPhone to power.
The wireless connection might not be stable between the two devices and cause iPhone migration to take hours, so you need to try a wired migration. Use a Lightning to USB 3 Camera Adapter and a Lightning to USB Cable to connect both iPhones and then try transferring data again.
If it still does not work, please check the cable. Please make sure that the cable is working well and no physical damage to it. You can try another cable or use a cable that Apple recommends.
After trying all the methods above, if you are still unable to complete data transfer on iPhone 13/12/11, you can turn to another tool to manually transfer data to a new iPhone on computer.
