Plan a safe iPhone or Android migration, including same-platform and cross-platform moves.
A transfer can copy apps and media while still losing authenticator registrations, message history, local files, health data, passwords, eSIM service, device-bound keys, app logins, or account recovery. Inventory first, back up, migrate through official tools, validate, and erase the old phone only after a cooling-off period.
Inventory data and identity dependencies
List platform account, primary email, phone number, carrier, SIM or eSIM, contacts, calendars, photos, videos, messages, files, notes, passwords, authenticators, passkeys, banking, health, work profiles, wearables, home controls, games, subscriptions, and apps with local-only data.
Prepare both devices and accounts
- Old phone updated where safe, charged, connected, and screen lock known
- Verified current backup plus separate copy of irreplaceable media where warranted
- Platform, email, carrier, password-manager, and recovery credentials available
- Multi-factor transfer or backup codes planned before phone number or device changes
- Enough new-device storage and supported operating system
- Employer, bank, health, authenticator, and encrypted-app migration instructions checked
Choose the migration path
| Path | Strength | Check closely |
|---|---|---|
| Direct device transfer | Often carries broad current state | Power, proximity, interruptions, and unsupported apps |
| Cloud restore | Useful without both devices together | Backup completeness, bandwidth, account access |
| Cross-platform tool | Moves supported common categories | Messages, purchases, app data, and ecosystem-specific services |
Migrate and validate in phases
- Create and verify backups.
- Securely start the official transfer process.
- Move carrier service at the planned point.
- Restore accounts, passwords, and authentication carefully.
- Compare counts and open representative data.
- Keep old phone locked and unchanged before final erase.
Do not lock out the recovery chain
- Wiping the old authenticator before registering the new one
- Trading in the old phone before message and photo verification
- Assuming an app icon means its local data transferred
- Losing eSIM, carrier PIN, or work enrollment instructions
Use a migration acceptance list
Record backup date, transfer method, carrier completion, categories and sample counts, critical-app sign-in, MFA moved, recovery tested, purchases or subscriptions restored, accessories re-paired, old-device erase approval, trade-in tracking, and new backup success. Avoid recording live passwords or codes.
