RDM Disk offline when Migrating SQL cluster in VMWare environment using SnapMirror

Hi,

I explain my case: We have to migrate a SQL cluster environment to new servers and new netapp (previous storage also netapp). We have made SnapMirror for Mon RDM (4 Mon). We see that you have copied everything exactly the same, but what changes is the serial number of the lun and the ID.
Steps:
We stop CLuster SQL.
We turn off the 2 VMs.
We disconnect the RDM disks from the 2 VMs.
We update and break snapmirror.
We present the new LUNs to the new servers.
We migrate the machines to the new servers and storage.
We edit the configuration and add the RDM disks exactly the same (only to the first VM).
We turn on the VM and find that the cluster does not start. In the disk manager the disks appear in "offline" mode and it does not allow us to put it online, because it says that the failover cluster is managing it.
In the failover cluster the disks appear disconnected and if we connect them there is an error.
Any ideas? Should the LUN ID be the same as the source ID?

thanks,
