Curently i have a Power edge 1650  with three 18gb  disks in Raid-5  Perc 3di

 

can i:

 

remove all three disks ,  change Perc raid to  raid-1

install two new disks and format them with raid-1, and install some operating system

 

then  remove these two raid-1 disks,  change Perc 3di back to raid-5  and install those three raid-5 disks what had at the begining. will it work?

 

can i simply switch between raid levels and disks  without loosing any data?  is disk order important?  disk0  to the first slot, etc.
