Migrate Whatsapp Business from another BSP to Pabbly Chatflow

How can I migrate from an existing BSP to Pabbly Chatflow? I have done the 2FA switch off as shown in one of your videos.
I cannot disassociate the existing number as I want to transfer the blue tick verification and template to your chatflow.
I am getting the error as shown in the screenshot.

Kindly assist with a specific video or instructions.

Thanks

Hi @MMSlg,

Please allow us some time to look into this concern. We will get back to you with an update soon.

I had a discussion with the technical team, and they informed me that it's not possible to connect the phone number with both your existing BSP and Pabbly Chatflow at the same time, as this is a restriction from Meta's end.

They also mentioned that even if the green tick is removed after migration, you can reapply for it.
