Before changing phones, check the available backup and restore settings so important conversations are not accidentally lost.
Backup availability and behavior can change with operating-system and WhatsApp updates.
WhatsApp on a New Phone
When moving WhatsApp to another phone, users should make sure they can access the phone number associated with their account and have completed any necessary backup or transfer process.
