Just a reminder that (at least in the Gen8) bays 1+2 are 6G, but bays 3+4 are 3G. So you might lose a tiny bit of speed if you pair them in a RAID5. For the "migration", to make it clean and simple, I would just copy the data temporarily on USB external disks; which I would use anyway for backups. JD
