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.
1. Select the array to migrate. From the drop down menu, select the RAID level to migrate to,
and then select the total number of drives to include in the array. A "+" appears above the
drive(s) to be added, and a "-" sign above the drive(s) to be removed.
2. Check the Confirm box and click Migrate.
