You can configure your cluster with a single disk (visible on all cluster-nodes) as a stand-in. WIth this you test all the IP-adresses, start-/stop-scripts, etc.. You said you want to use new IP-ranges anyways, so you can test with your new production-IPs safely while the old cluster is still running.

On the day of the transition you

- zone the datadisks of your old cluster to the new cluster-nodes (you need SAN support for this)

- throw away your (test-)VG and the RG residing on it.

- run cfgmgr to see the newly discovered discs, import the VGs on all nodes (be sure to end with concurrent-capable Vgs), run a clmgr disco vg ("discover VGs") on one node to make the VGs available in HACMP and run the RG-definition from above (clmgr add rg ...) again. It is that simple.

Do yourself a favour: when importing the VGs on all nodes make sure the same VG gets the same major number on all nodes. It will work without that too, but it makes keeping track easier that way. I even try to have the same hdisk-numbers on all nodes, so that hdiskXX on node1 is also hdiskXX on node2, etc..

I hope that helps.
