Group Contact list transfer

Hi

I am planning to change my BB device (9720) to Z 3. I have sms groups (6 of them each having 100 contacts) While I am able to transfer my contacts, when I changed my BB earlier I couldn't transfer the groups. It takes lot of time to make these groups again. need help suggestion.

I believe you will have to set up the groups again on the BB10 device as I see no way to transfer them over.
