You can download the free program made by Keysoftservice Musical backup database converter Kn2000.kn3000.kn3500.kn500.kn6000.kn6500 to kn7000.
I already tried it and it works ...what a difference this make.
I had a backup from my hdsx6 and transferred everything with this new program.
I you have a backup then you must have this one.
