Migrating traditional SQL server cluster to new SAN

We are running Biztalk 2013 R2 on an Active/Active 2-node traditional Windows 2012 server cluster on VMWare.

All LUNS are physical RDM's attached to EMC XtremeIO.

Is it possible or recommended to present new LUNS from new NetApp SAN and migrate cluster?

Or is building a new cluster and re-pointing Biztalk a better alternative?

First option seems to reduce amount of Biztalk work which would be good.

Thanks,

Morrisos
