Migration from Business App to Business API
Migration path from a WhatsApp Business app to the WhatsApp Business API
WhatsApp offers a migration path from the WhatsApp Business App to the WhatsApp Business API.
Be mindful of the fact that there is no way back to the WhatsApp Business App following an upgrade. Your former WhatsApp Business App can not be used afterward.

WhatsApp Business -> WhatsApp Business API

Go through signup processes to submit the phone number to us. Instructions on the process are here for the classic signup and here for the embedded signup. It is required a WhatsApp for Business account associated with that phone number. While you are migrating your number all incoming messages will be queued by WhatsApp servers and delivered after a successful migration.
From here there is no way back; existing chats (history) cannot be imported once the number has been upgraded to the WhatsApp API. Your former WhatsApp Business app can not be used afterward.
For Classic Signup, you must now complete the number registration as described here.

Any more questions?

Can I use a phone number that is already on WhatsApp?

Yes. If that phone number has not been used on WhatsApp Business API, you can use that phone number. Follow the migration steps outlined here to reuse that phone number. If the number has been used on the WhatsApp Business API, but with another BSP, you must migrate it to 360dialog.

Will I lose data?

Deleting the WhatsApp account on your Android or iPhone will cause any incoming messages to be queued by the WhatsApp servers and then subsequently delivered upon successful registration.

Can I import my backup using the WhatsApp for Business API?

There is currently no option to import previous conversations.

Can I migrate my number from another Business Solution Provider (BSP)?

Yes! You can now migrate phone numbers between WABAs and BSPs. Please check out our migration guide for more information.

Will the migration affect Official Business Account approval?

Official Business Account approval is only available for selected WhatsApp for Business API clients. It's not affected by migration. Once the number has been upgraded to the WhatsApp for Business API it is possible to apply for the OBA status.
