You should see the lun in engine if you are logged in to the iscsi target.

Are you sure this lun is configured properly so the new host can access it?

Do you have correct /etc/iscsi/initiatorname.iscsi on the host?

This is not a good idea, not sure that it is related to your problem,
but what you should do is:

1. Shutdown vms using this storage domain
2. Put storage domain to maintenance
3. Detach storage domain
4. Import storage domain on the other setup - this will work only
after you see the lun on the other setup
