if you did a back up on ya pc/dm ...then just link it up via usb and restore ya back up and alot of stuff that you may have had on a mc should be able to be put back when the mc is inserted in the new berry
However, some purchased applications are PIN specific. You may or may not be able to transfer them to a different device.
You would need to contact to point of purchase to see if they will allow the applications to be transferred. Don't be surprised if they say that you can't do it.
