It would take a long time assuming you have a bunch of contacts but it can be done. I would recommend if it is blackberry to blackberry that you download Desktop Manager(find on Blackberry's site) and transfer contacts through that. Otherwise you will have to transfer all the contacts one by one through bluetooth.
Just attach them to a MMS BB to BB. Over BT, it is tough unless that BT profile is loaded. For security that cannot be done in many cases dev to dev but in my case does not even work to my car but it did to a couple samsung devices however there were a few quirks in doing it aroud special characters in names ans with pauses.

Why don't you transfer the entire adre�book via bluetooth?
If you connect your BB with another device (another BB or any other handset) there is an option in the BB-BT-menue to transfer the whole adre�book. Works very good.
