For your AppWorld obtained apps, using the exact same BBID is required on both devices...this transfers all things associated to your BBID account from your old device to your new one, including AppWorld purchase/download records. Refer:
Do keep in mind that if the developer of an app has not made a version compatible with your new device/OS level, then it will not be available for installation to your new device.
For apps obtained elsewhere, you must look to that "elsewhere" to determine how to transfer your apps to your new device.
