Plan a device replacement without losing data

For [OLD DEVICE], [NEW DEVICE] and [IMPORTANT DATA], prepare a transfer checklist that covers backups, account recovery, authenticator access, local files, app settings and physical accessories. Separate what can be copied from what must be re-enrolled. Include a verification step on the new device before any sign-out, wipe or disposal, and a rollback path if transfer fails. Do not ask for passwords or perform a factory reset. Check that critical data has two independently readable copies and that the owner can still access recovery channels afterward.
