Migrating a Disk Array
On SuperTrak, RAID level migration is performed on the disk array but it applies
to the logical drives. The action of migrating a disk array means either or both:

Increase the number of disk drives (sometimes called expansion)
For a list of Migration options and other important information, see “RAID Level
