How to transfer Whatsapp Blackberry 10 backup to iphone?

Hi I have a blackberry 10 (Blackberry Classic) phone I can do a manual backup of my conversations and it stores it locally on my phone as a "crypt" file.


Does anyone know how to can restore this backup on a new iPhone? Or any ways I can transfer all my whatsapp chats to a new iPhone

thanks

Not that I'm aware of, whatsapp not support transfer chat back up cross platform, right now only Beta from bb10 to Android

don't believe so.
