If you have already got the latest iPhone 14 mobile phone, in addition to transferring data from the old iPhone to the new iPhone through the [Quick Start] function, you can also perform data migration through the iCloud that comes with the system.
The following are the specific steps to migrate data through iCloud:
1. On the old iPhone, open [Settings] - [General], slide to the bottom and select [Transfer or restore iPhone]. If you do not see this option, you need to upgrade the iOS system first.
2. Follow the on-screen prompts to upload the data of the old iPhone to iCloud space. Once uploaded, apps and data are automatically kept up to date until you start setting up your new iPhone.
3. When setting up a new iPhone, in the [App and Data Interface], select [Restore from iCloud Backup], and then choose to restore from the version backed up by the old iPhone.
Note: The free iCloud backup storage expires 21 days after you start iCloud backup. If you do not restore to your new iPhone in time, you can apply for an extension of time.
