5.6.5 Migrations

Different from Expansion, which enlarges an array by adding hard drives to a fixed
RAID level, Migration changes the RAID level of an array. It allows live changes to the
RAID without the need to delete the array and rebuild. This can be useful when new
drives have been added, and a new array type needs to be created.
Example 1:
RAID 5 (12 drives) –Migrating RAID 0 ( >11 drives)
RAID 5 (12 drives) –Migrating RAID 6 ( >13 drives)
RAID 5 (12 drives) –Migrating RAID 0+1 ( >22 drives)
Example 2:
Example 3:
Note
The new hard drive must larger than the existing drives of array.
Follow the steps below to select an array to migrate. This changes the RAID level, such
as from RAID 1 to RAID 5.
