I find technology a bit of a challenge. I have a 4 bay DS NAS, 4 x 2tb drives with no raid configured and a drive, (disc 4), with a degraded partition. It was time to get another NAS - should have done it a couple of years ago. The new one is another DS 4 bay with 4 x 4tb drives and raid 5 configured. How difficult is it to copy all my data from the old NAS to the new one? My learning style is by reading not pictures. Would someone e be kind d enough to explain fairly simply how to do this if at all possible? X
