Perhaps I'm stating the obvious, but here goes:
You could use SAN zoning of the affected LUN's to keep multiple hosts

to make the LUN's visible to the new host, then import. When the old
host reboots, it won't find any zpool. Better safe than sorry....
Yes, that would work. But what or who does the "change the zoning"
process? If it's a human, then failover could take hours; that's not
often good enough. If it's automated, then you need the Cluster
infrastructure to decide when to do it.
