If you can attach both new and old SANs to the same cluster then you could add OCR and voting disk on the new SAN and remove from the old? I have migrated single instance databases from old to new SAN on ASM using RMAN and the "backup as copy" method which was simple and had minimal downtime. Just need to manually sort out the move of the controlfiles, redo logs, Archivelogs etc but that can be sorted out PMcM _DISCLAIMER: This message is intended only for the use of the person(s) ("the intended recipient(s)") to whom it is addressed.
