Preparation (All Methods)

Method 2: iCloud Backup & Restore

Wireless, no cables – ideal if phones not nearby.

  1. On old iPhone: Settings → [Your Name] → iCloud → iCloud Backup → Back Up Now
  2. Wait for backup complete (check date/time)
  3. On new iPhone 17: Setup → "Restore from iCloud Backup" → sign in → choose latest backup
  4. Keep connected to Wi-Fi until complete

Method 3: Mac/PC Backup & Restore (Encrypted & Complete)

Best for large data or no iCloud space.
