Overview
The migration process means that a phone number that is already registered in the WhatsApp Business API can be moved between WhatsApp Business API accounts. This allows for businesses to change BSP's (Business Solution Provider) or move their number to a new account, but only if the source and destination Facebook Business Manager IDs are the same. After being migrated, a phone number keeps its display name, quality rating, messaging limits, Oļ¬cial Business Account status, and any quality message templates previously approved as soon as they do not exceed the maximum capacity of templates per WABA (250 max).
What Is / Isn't Migrated in the process?
Here is a summary:
Template Messages and chat history migration
Only the high-quality message templates are migrated on this process. In practice, they are copied to the destination WABA. These templates do not need to go through review again and can be sent immediately. Low quality, rejected, or pending templates are not migrated. Any existing message templates in the destination WABA will not be overwritten. Messages and chat history are not migrated with this process.
Official Business Accounts (Green Badge)
Official Business Accounts (OBA's) can be migrated between WABA's. The only requirement is that the two-factor authentication requires to be disabled during the migration process. It can be re-enabled after the number is migrated.
Requirements for phone numbers to be migrated:
You must have physical access to be able to receive and verify a 6 Digit PIN code through SMS or Voice Call per every number to be migrated. The WhatsApp Business Account connected to the number to be ported must be verified by Facebook.
Preparation checklist
Please note that this requires to be the Facebook Business Manager ID of the Business Manager that is the owner of the account. If the Business Manager only has access to it but is not the owner, the migration will not work.
