GPFS move from SAN RAID 5 to SAN RAID 1/0

I understand how to move a regular JFS file system from one physical volume to another, but what should I consider to move volumes participating in a GPFS cluster? Can I use the same processes that I use for JFS and JFS2? Do I set up another filesystem and copy to it?

Thanks for your input. Can you tell me why I should use tar instead of cpio or something similar?
Thanks,

then you must go with POSIX-defined pax, there is no preference on tar or whatever.

Thanks for your comments. Here's what we ended up doing...
We created a second GPFS volume group on new disks and then copied via cpio to the new. Of course we had to use all the mm commands that come with GPFS, but overall things went well.
Thanks,
Dan
