Migrating Windows 2003 Cluster to new data center

We are in the middle of a data center migration and have several windows 2003 clusters (active/passive) that need to move sites. Any server in the new site recieves a new IP address as well. (we do have the doc on how to re-ip a cluster) We have SRDF replication the data between the old DC and the new DC. Can we use srdf to move the data, and will the cluster see the disks as before? This is an exchange 2007 cluster, and we cannot upgrade to windows 2008 for the cluster spanning subnets option.
