I am in the middle of preparing for just such a move and have an SR with Oracle 
to verify the process.  Unfortunately, just as with the recent thread here, I 
hold little hope of getting timely assistance from them.

I have done a single instance move with ASM by adding the LUNS from the new 
array into the diskgroup, allowing it to rebalance then removing the LUNs from 
the old array.  Worked fine.

If you come up with a method to deal with OCR/voting disks, I'd be interested 
comparing notes.

Good luck

Subject: Re: moving to a new san array

I have done this, and as I recall while it is a touchy process (that is, you 
dont want to make any mistakes since they are hard to recover from), it is 
fairly straightforward.  I moved 10.2 rac on windows to a new san with a 
clusterware upgrade to 11.1. in the process.  I will see if I can find my notes 
on the subject.   This is definitely the sort of exercise you want to to script 
and practice once or twice before you do it for real.  If you cant rehearse it, 
make sure you make real good notes.
