In general its the responsibility of the application/admin triggering
the migration to ensure that the destination host has the same storage
and network configuration. There's nothing special about iSCSI in this
regard really - FibreChannel/NFS/Cluster-LVM/etc all have the same
core requirements.   If you have a bunch of hosts you wish to migrate
between, then you need to configure them all to have matching resources
