I am looking to snap mirror volumes form an older 4 node to a new 4 node cluster. I plan to snapmirror volumes from one cluster to the other. I would also like to limit downtime for my NFS hosts. Once the data has been snapmirrored to the new cluster can reassign the data lif IPs from the old cluster to the cluster. The new cluster will be on the same VLAN and subnet as the old cluster. I realize at some point my hosts will probably drop the NFS connection to the NetApp storage as we transistion from old to new. I want to minimalize downtime and not have the hosts remount the storage (data LIF) if possible.
Can this be done? Any tips of tricks please pass my way. Thanks.
