The following table lists the disk requirements for a new RAID array for various migrating combinations.
From | To | New Array Disk Requirements | |
| RAID 0 | m > n | |
| Number of disks in the new array must be greater than the original array. | ||
|
| ||
| RAID 1 | m =2, n =1 | |
| RAID 1 array must include two disks, converted from a one disk RAID 0 | ||
RAID 0 |
| array. | |
| m >= 2 x n | ||
|
| ||
| RAID 0+1 | Number of RAID 0+1 disks must be equal to or greater than twice the | |
|
| number of RAID 0 disks. | |
| RAID5 | m >= n+1 | |
|
|
| |
| RAID 0 | No additional restrictions. | |
|
|
| |
RAID 1 | RAID 1 | ** Not a valid combination ** | |
|

RAID 0+1 | No additional restrictions. | ||

|
|
| |
| RAID 5 | m >= 3 | |
|
|
| |
|
| m >= n2 | |
| RAID 0 | Number of RAID 0 disks must be equal to or greater than half the number | |
|
