Migration finishes after verification
A transfer tool may move contacts, photographs and settings while leaving behind specialist application files, local downloads, authentication access, licences or data stored under another account. Keep the old device until the new one has passed a written check.
Update and back up the old device, confirm account and encryption recovery, inventory data and applications, then use a supported transfer route. Verify important files, messages, accounts, authentication, peripherals and backups on the new device before signing out or erasing the old one.
Prepare the move before setup begins
- Current tested backup of important data
- Old-device passcode and main account password
- Password-manager access and recovery information
- Authenticator, security-key and recovery-code plan
- SIM, eSIM, telephone number and carrier process
- Encryption or BitLocker recovery keys
- Application licences, installers and deauthorisation limits
- Enough destination and temporary cloud storage
- Supported cable, adapter, Wi-Fi and power
- Time when both devices can remain available
Choose a supported transfer route
| Route | Strength | Checks before relying on it |
|---|---|---|
| Direct device-to-device | Can move a broad set of data and settings during initial setup without first uploading everything. | Compatibility, cable or network, power, storage, interruption behaviour and which application data is excluded. |
| Cloud backup and restore | Works when the old device is unavailable and preserves a separate recovery copy. | Backup completion, account access, storage allowance, version compatibility, download time and excluded data. |
| Computer or external backup | Provides a local route and can protect large file collections or encrypted device backups. | Backup encryption password, application compatibility, external-drive health and complete restore instructions. |
| Manual export and import | Creates visible, portable copies for specialist applications or cross-platform moves. | Export format, metadata, encryption, import test, duplicate handling and secure deletion of temporary copies. |
Verify the new device by category
Identity and communication
Test calls, mobile service, messages, email, contacts, calendars, password manager, multifactor authentication and account recovery.
Files and memories
Open current and older documents, photographs, videos, downloads, notes, voice recordings and application-specific projects.
Applications and licences
Install from trusted sources, sign in, confirm subscription or licence status and test representative work rather than checking only the icon.
Hardware and access
Test biometrics, accessibility, printers, displays, storage, docks, hearing devices, cameras, microphones and other essential peripherals.
Secure and back up the destination
- Install current supported updates. Include operating system, applications, browser, security and firmware.
- Use strong device access. Configure a proper passcode or password and biometrics where suitable.
- Confirm encryption and recovery. Record recovery keys without storing them only on the protected device.
- Review permissions. Migration can carry old access choices that no longer serve a purpose.
- Start the new backup. Do not assume the old backup job automatically protects the replacement.
- Keep the old device temporarily. Retain it securely until important data, services and backup have been verified.
Use current platform instructions for the exact move: Android-to-Android transfer, Apple iPhone and iPad transfer, or Windows Backup and restore. Features and exclusions change, so the verification list remains necessary.
Device migration FAQs
When can I erase the old device?
Only after important data opens correctly on the new device, communication and authentication work, essential applications and licences are confirmed, peripherals are tested and the new backup has completed and been checked.
Will every application move automatically?
No. Some applications must be reinstalled, signed into or relicensed; others store data in their own cloud, require a separate export or cannot move between operating systems. Check each essential application before erasing the source.
What should I do with authentication apps during migration?
Follow the provider’s transfer or recovery process while the old device still works. Keep recovery codes or security keys available and test access to critical accounts on the new device before removing the old authenticator.
