Stuck on “Preparing to transfer” when migrating to iPhone 14 Pro

Got it pengzhan,

If there is data that does not sync with iCloud, it would be included in the full phone backup. You can learn more about that here: What does iCloud back up? - Apple Support

If you prefer to use Quick Start, we want to ensure you get that option. If you followed each step in the article that was provided previously, (What does iCloud back up? - Apple Support), we recommend reaching out to Apple Support so they can look into this in more detail. You can do that here: Contact - Official Apple Support

Kindest regards.

Hi there pengzhan,

Welcome to Apple Support Communities. We understand you are trying to set up your new iPhone and walk through the Quick Start transfer option from your old iPhone. We have some questions to help clarify the issue and will provide a few steps to get started.

1. Do you have a backup of your old iPhone 11 Pro?
2. Which iPhone 14 Pro storage model do you have?
3. Have both iPhones been connected to a 12W or higher power adapter while trying to transfer?
4. Are both iPhones near each other while you've had the transfer going?

Then, confirm the steps in this article and reply back with how it's going: Use Quick Start to transfer data to a new iPhone or iPad

Best regards.

Understood pengzhan,

Is the old iPhone in working order? If so, are you able to back it up to iCloud? Here's the details on how: How to back up your iPhone or iPad with iCloud - Apple Support

1. Connect your device to a Wi-Fi network.
2. Go to Settings > [your name], and tap iCloud.
3. Tap iCloud Backup.
4. Tap Back Up Now. Stay connected to your Wi-Fi network until the process ends. Under Back Up Now, you'll see the date and time of your last backup. If you get an alert that you don't have enough iCloud storage space to complete the backup, follow the onscreen steps to upgrade your iCloud storage.

Then try to restore the backup to the new iPhone and let us know what happens.

Thanks!
