Changing the RAID Type of a RAID Group
You can change the RAID type of an existing RAID group online, without losing access to data or any
interruption to NAS services. Changing the RAID type of a RAID group is called RAID migration. QTS allows
the following migrations.
Original RAID Type
New RAID Type
Additional Disks Required
Single
RAID 1
One
RAID 1
RAID 5
One or more
RAID 5
RAID 6
One or more
Tip
Migration from a single disk to RAID 6 is performed in stages. First migrate the group to
RAID 1, then to RAID 5, and then finally to RAID 6.
