changing IP addresses of MS SQL server in clustered environment

Hi all,

I have a MS SQL server 2005 in a clustered environment (with 4 physical
servers/cluster nodes). I need to move the cluster to another office,
which implies that I need to reassign IP addresses of all cluster nodes
as well as SQL servers (goups) installed on this cluster.

Is it possible to change the IPs without damaging the cluster? If so,
could you please provide me with some information on this subject?

Thanks,
aleu
