iPhone Migration Not Working iOS 14

I’ve bought an iPhone 12 Pro (256GB) and need to transfer data from my iPhone 6S. 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 get the latest iPhone. Apple’s first 5G iPhone has come. It is time to grab your 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.

Why is iPhone Quick Start not working?
Technically, the issue that iPhone migration failed is often caused by poor network conditions or system glitches. You tried to force restart iPhone several times but only to get stuck on “transfer directly from iphone not working loop". If the issue has not been fixed, the loop won't end.

You might have problems transferring iPhone data with Quick Start. Follow the next section to know how to fix it.

Unable to Complete Data Transfer

5 Solutions for iPhone migration not working

Before you use Quick Start to do iPhone migration, you need to do some preparation:
●Factory reset the target iPhone if it has been set up.
●Turn on Bluetooth on the source iPhone.
●Put the two iPhones close to each other.

Note: If the two iPhones get far from each other during data transfer, you would get the error message that Move Device Closer to Continue, and sometimes the process gets stuck.

#1 Update the target iPhone: If you use Quick Start to set up iPhone but 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.

#2 Reboot the source iPhone: 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.

#3 Insert SIM card to source iPhone: 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.

#4 Plug both iPhone to power: 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.

#5 Use wired iPhone migration: The wireless connection might not be stable between the two devices and cause iPhone migration taking 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 QuickStart iPhone Migration keeps failing, don’t worry, because you could have other plans for that.
