Transfer Whatsapp Business from Android to Iphone

As others have mentioned, there is no official way to transfer WhatsApp chats from Android to iPhone. But there are some third-party utilities like this that can help you transfer WhatsApp Business chat history from android to iPhone.

I switched from a Samsung Galaxy S9 to iPhone 11 and I transferred my old chats with the help of this tool. I don't use WhatsApp Business, but I'm sure they do have some different app that works with WhatsApp Business. I may remind you that this tool is not free. It is a paid one. If you don't want to pay for a third-party app, you can consider emailing your chats as explained here.

Not possible. However...

WhatsApp is not an Apple product. Contact the app developer here --> App Support or WhatsApp FAQ or Restoring your chat history - WhatsApp FAQ

You can only back up and restore WhatsApp chats on the same technology device. Facebook (who owns WhatsApp) does not provide a means to transfer content between technologies. This is covered in the WhatsApp FAQ (see the link in SravanKrA’s post).

I already told you that it is not possible.
