Angel,
Im a bit late but I haven't seen much follow up except one reply
assuming that you need to move to the new storage.
Based on your post I would rather assume that yo physically moving
machines themselves as well as storage so your move might be more
difficult.
Single instance databases live well when changing IP's or hostnames -
just make sure that network configurations is corrected like listener
and tnsnames.ora files.
RAC is more complex but here is just an overview of few obvious options.
If you hostnames are changed than clean way wold be to re-instal CRS
and Oracle homes. Another way would be a slight hack depending how
adventurous you feel. I posted an example how to do change hostnames
in RAC cluster without re-install - http://www.pythian.com/blogs/482/changing-hostnames-in-oracle-rac
.
If you don't need to change hostnames but only IP's than you probably
will be fine reconfiguring your VIPs (http://www.pythian.com/blogs/210/oracle-10g-r2-rac-vip-on-wrong-interface
) and interconnect (previous link as before has reference as well).
If you have more specific questions - let me know.

We are consolidating data centers and need to move a couple of Oracle
databases, including a 3 node production RAC. This will require
changing the IP address of every machine that is moved.
I am opening an SR with Oracle, but real world pointers / tips /
gotcha's / how-to's etc. on how to do this would be greatly
appreciated.
Oracle versions are 9.2.0.4, 10.1.0.5 (RAC) and 10.2.01 on Red Hat
Enterprise Linux AS release 3 (Taroon Update 1)
(and yes, once the machines are moved we plan to upgrade Oracle)
Thanks!
