Online Expand RAID 6 HP P410i Controller

Hi HP experts,

My DL380 G7 using HP P410i 512 MB Memory + Battery and license Smart Array Advance Pack 1

I have 3 Array :

1. 2 x 146 GB ( RAID 1 ) for Operating System
2. 6 x 600GB (RAID 50) for Data
3. 8 x 600GB (RAID 6)For Data

I would like to expand the RAID 6 Array and extend the logical drive in this array, i  am considering delete RAID50 Array and add 6 free disks to RAID6 Array. ( Please open the attachment for detail Hardware and software )

 Does my Hardware and software support me to expand RAID6 array and its logical drive without losing data ?

Can i expand array online?

Thank you so much
