The term “Migration” means either or both of the following:
• Change the RAID level of a logical drive.
• Expand the storage capacity of a logical drive.
Before you begin a migration, examine your current disk array to determine whether:
• The physical drives in your array can support the target RAID level.
• Thereissufcientcapacitytoaccommodatethetargetlogicaldrivesize.
If you need to add physical drives to your array, be sure there are unassigned physical drives are
installed in your RAID system before you begin migration.
