Re: Cluster Swap
I'm not a LH crack, but remote snapshots would be a solution.

Re: Cluster Swap
Beyond that, like Patrick said. Snapshot the volumes from the old cluster to the new one. Then get a maintenance window, do one final snapshot where there are no new changes, promote the volumes to primary, and finally change all your iSCSI initiators to point to the new cluster (and assign volume access within the cmc).

SolutionSAN/iQ will then move the volume in the background while your servers remain attached to it. You will need to amend any iSCSI initiators so that they reference the new cluster going forward but the iSCSI connection will remain in operation following the move of the volume.
Once all of the volumes have been moved over then you can either reprovision the original storage as second tier or remove the cluster completely and decommission it.
Regards, Mike.

Re: Cluster Swap
We've had issues with that type of move with high transaction loads (like SQL Server volumes). So there may be a momentary drop when you move to the new cluster. (Enough of a drop to anger SQL.) While the same drop was there for fileshares and the such, they seem to be a lot more forgiving during the cluster migration.
