WhatsApp error 2388103 Migration blocked — destination account not fully set up

The number could not be moved because the WhatsApp Business Account you are moving it into has not been set up to receive message updates (webhooks) yet. WhatsApp will not complete the migration until that setup exists on the destination account.

1. Contact LetsBot support so your WhatsApp connection is set up to receive message updates (webhooks) on the destination WhatsApp Business Account.
2. Retry the migration once that setup is confirmed.

This number is eligible to be added straight to your WhatsApp account, so it does not need to go through the migration process at all. That is why the migration attempt was refused.

1. Add the number directly to your WhatsApp Business Account instead of migrating it.
2. Register the number and complete its verification.

The number could not be moved because its display name — the business name your customers see — is either not set at all or not approved. A display name change that is still waiting for review also blocks the move.

1. Set a display name for your business number if it does not have one, then get that display name approved.
2. If a display name change is still under review, wait until it is decided before retrying.
3. Retry the migration once the name shows as approved.

The number could not be moved because the WhatsApp Business Account it currently sits under is not set up correctly: that account must be approved, and its permission to message on behalf of the business must be approved too. This may mean the account still uses the On-Behalf-Of ownership model, which is now deprecated.

1. Contact WhatsApp support and mention that the source account may still use the deprecated On-Behalf-Of ownership model.
2. Retry the migration after support confirms the source account is set up correctly.

The migration was refused because your WhatsApp account has no payment account attached. WhatsApp requires an active credit line on the account so that messages can be sent once the number has moved.

1. Contact LetsBot support so an active credit line is set up on the WhatsApp account.
2. Retry the migration once support confirms the credit line is in place.

Something went wrong while your number was being migrated, and the move did not complete. No specific reason was given for the failure.

1. Wait a while, then try the migration again.
2. If it keeps failing, contact support.

The number could not be moved because it belongs to a different Business Manager account. WhatsApp only allows the move when the account you are moving from and the account you are moving into represent the same business.

1. Check which business each of the two WhatsApp Business Accounts represents.
2. Migrate the number into a WhatsApp Business Account that is messaging for the same business as the source account.

The move was blocked because the WhatsApp Business Account you are moving the number into is not approved. WhatsApp requires the destination account to be approved before any number can be migrated into it.

1. Complete business verification for the business.
2. Make sure the destination WhatsApp Business Account's review status shows as approved.
3. Retry the migration once it is approved.

The number could not be moved because the destination WhatsApp Business Account's "Messaging For" request has not been approved. Until your client accepts that request, WhatsApp will not allow the number in.

1. Ask your client to open Meta Business Suite and accept your "Messaging For" request.
2. Retry the migration once they have accepted it.
