Use the steps in this section to back up your previous device in iTunes and to transfer the backup to your new device.
If you don't encrypt your iTunes backup, Health and Activity data from your iOS device or Apple Watch won't be saved.
Make an iTunes backup of your previous device
- Connect your previous device to your computer.
- Open iTunes and make sure that you have the latest version.
- Select your device.
- If you want to save Health and Activity data from your iOS device or Apple Watch, you need to encrypt your backup: Select the box called Encrypt [device] backup and make a memorable password.
Write down your password and store it somewhere safe, because there's no way to recover your iTunes backups without this password.If you don't need to save Health and Activity data, you can make a backup that isn't encrypted. Just click Back Up Now.
- After the process completes, make sure that your backup finished successfully in iTunes Preferences > Devices. You should see the name of your device and the date and time that iTunes created the backup. If you encrypted your backup, you should also see beside your device's name.
Transfer your SIM card or contact your carrier
If your new device needs a SIM card, here's what you need to do:
- If your carrier gave you a new SIM card, put it in your new device.
- If your new device uses the same kind of SIM card as your previous device, transfer the SIM to your new device.
- If your new device needs a different kind of SIM card than what you have, or if you aren't sure, contact your carrier.
Then use the steps below to transfer your iTunes backup to your new device.
Transfer your iTunes backup to your new device
- Turn on your new device. A "Hello" screen should appear. If you already set up your new device, you need to erase it before you can use these steps.*
- Follow the steps until you see the Apps & Data screen, then tap Restore from iTunes Backup > next.
- Connect your new device to the computer that you used to back up your previous device.
- Open iTunes on your computer and select your device.
- Select Restore Backup. Then choose a backup. Make sure it's the correct one by looking at the date and size of each. If asked to update to a newer version of iOS, learn what to do.
- If you need to restore from an encrypted backup, enter your password when asked.
- Wait for the restore process to finish, then complete the rest of the setup steps on your iOS device. If possible, keep your device connected to Wi-Fi and plugged into power after setup. This allows content like your photos, music, and apps stored in iCloud to automatically download back to your device.
* To erase your device, tap Settings > General > Reset > Erase All Content and Settings. This will erase any data that's currently on your device. After you erase it, your device restarts and the "Hello" screen appears.
