Transferring BBM Chat history help !

Hello

I'm new here and I want to pick some knowledgeable BB brains :)

I need to transfer my BBM Chat history from my old 9000 bold to my new 9780which I will be purchasing tmw. The chat history is always saved to 'device' and I know that if I switch to save in 'media' then this will only be effective for the chats I have after I do this.

I just need for the chat history to be intact for each person on my new BB like it was on my old one,because I have work related information and it would be too long to send chat to email etc. Is this at all possible ?:confused:

Thank you, any help much appreciated.
