Any advice please

We are looking to upgrade OS on our 270 (currently V5R2)

We believe we need a larger disk for our load source in order to do this, 
and are looking at moving to 17.5gb or 35gb disk drives.

Our current disk config is as follows :

Parity Set 1
4 * 6.4gb 6717

Parity Set 2
8 * 7.5gb 6717 (including load source)

Physically we  have 2 * 6 slot units. Both currently full.
The first unit contains 4 drives from Parity Set 2 (including the load 
source) and 2 from Parity set 1
The second unit contains 4 drives from Parity Set 2 and 2 from Parity set 
1

Current disk usage is 57%

Is it possible, by some combination of removing existing drives, switching

off parity, adding the new larger drives, to move load source to the 
larger disks whilst avoiding full restore ?
