NW-a55 to NW-a306 - SD Card Question

Question: I am wondering if the SD card I am using in my a55 will work as-is in the a306, or if I will need to reformat the card and start over or get a new card (all of my library is saved locally and backed up). Does anyone know?

Sad story: the screen on my a55 is starting to delaminate/decay and before it gets too sad to look at, I decided to order the a306 and give it a try. Once I settle on a new player, I might try to repair the a55, since it is still functional in all other aspects.
