Easiest way to migrate your phone is download a free backup application from Blackberry app world. Once your download it, it will backup your whole phone, contacts, text, photos, videos, bookmarks ect. Then when you get the new phone you just download the app again and log in to your account and all your data immediately loads on the phone. very easy!
Hope that helps! Good luck.
