I have a 722k arriving tomorrow and Im gonna use it in my room and move my existing 612 to a extra bedroom, my question.. I have a external hard drive to back up my 612 recordings, can I move them to my 722k ones its activated on my account? The 612 will still stay on the account as well if that makes any difference. I just wanted to ask before I transferred everything from my 612 to the hard drive.
