That works, no doubt.
But it needs quite much downtime as the data migration is so slow :( We
have had 10-30Gb/hour. So with 1 Tb cluster data it would take awhile to
migrate. And need to change homedir attributes, mappings, create new
cluster resources.

For me this sounds much more interesting but I have never done it
before myself. Never had to replace a SAN before.. but need to, soon.
As I understood you wouldn't have to change everything, just mirror the
data and the remove old storage. see this:
