RAID Level Migration
To migrate a disk array is to do one or both:
•
•
Change its RAID level
•
Increase the number of disk drives (sometimes called Expansion)
Migration takes place on an existing Functional disk array without disturbing the existing data. While the disk
array is migrating, you can access the data as before. When migration is complete, your disk array will have a
different RAID level and/or a larger capacity.
