I am currently using an older Drobo FS storage box with three 3TB drives. I want to keep the data on them, but I also want to move it to a new DIY box that I am building now with unRAID. I am thinking of getting an 8TH Parity drive, but how should I handle moving those older drives and data over? Out of the 9TB there, some of it is protected, and I have about 4TB of actual data on those. I'm going thru the guides now but it's not 100% clear to me. I of course don't want to screw this up and lose the data, while having the ultimate outcome of still using those drives.
Thanks!
