Expand RAID 0 set on Multiple RAID levels configuration on one array.

Hi All

I have a HP DL185 G5 with 8 x 300GB disks split in 2 arrays A and B.

Array A: 2x300GB (for OS)
Array B: 6x300GB (for DATA)

Configuration:
The Array B has two Logical Volumes:
Volume 1: 512GB using RAID 1+0 (Used 1024GB of 1800GB) spread across the 6 disks in array B.

Volume 2: 512GB using RAID 0 (Used 512GB of 1800GB) spread across the 6 disks in array B.

Unused Space: 140GB

My Case:
I still have 4 empty disk slots.
I want to change the RAID 0 on array B to RAID 1+0 with volume size 0f 512GB.
Question:
Will adding 2x300GB to the server in Array B and then using Migrate RAID option on Logical volume 2 help me fulfill what I am trying to achieve here?

I haven't used the Migrate RAID option before and thus it concerns me if having another volume with RAID 1+0 on the same Array could cause issues.

Any help would be highly appreciated.
