[CrackBerry Question]

I use BBM for work but do not have an enterprise account. I save my chat history. I've had my keyone for a year and after being dropped too many times it was dying. I bought another keyone and logged in using same bbm account and found none of my chat history migrated over. I still need some info from the chats on my old phone. If i log back in on it, will I lose the chat history on the new phone (it is set to save as well)?

thanks!!
