Whatsapp messages from BB 9700 to Z10?

Hi,

How can I transfer my old whatsapp messages form BB 9700 to my new Z10?
Thanks a lot.

I think there's an option to save the conversation on the memory card and then the WhatsApp app on a new phone automatically reads it.

Yep, but It is too late, cause I recycled my old BB9700 and I forgot to save the messages. So I have at the moment the old messagestroe.db . I found a whatsapp folder on my Z10, I copied the old messagestore.db ther, but that is not working.

Any other solutions?
Thanks.
