If you take a microSD card out of one NOOK and put it into a replacement NOOK, the personal files on the microSD card will be available on the replacement NOOK.
B&N content in the library will be available on the replacement NOOK after registration.
B&N content that is not in your library (that has been copied to personal folders) will also be available, if you placed it on the supplemental microSD card or copy it back to your NOOK from a personal computer using USB.
