Hi,

I suggest another solution for you (which wasn't tested as a whole but much simpler in my opinion).

 On the source environment:
- Create a local DC with a single local storage domain (let's call it sd1). 
- Deactivate and detach the FC domain from the existing shared DC and attach it to the local DC (From oVirt 4.1, attaching a shared storage domain to a local data center is possible). 
- Register FC domain VMs (from 'VM import' sub-tab under the FC domain).
- Move the disks from the FC domain to the local domain.
- Deactivate, detach and remove without format the local domain from the source environment.
- Maintenance the host in the local data center (let's call it host1).

 On the destination environment:
- Add host1 to the destination environment and create a local data center with this host and a new local domain.
- Import the existing local domain (sd1) to the local data center and register its VMs.
- Deactivate and detach the iSCSI domain from the existing data center and attach it to the local data center.
- Move all the disks from the local domain to the iSCSI domain.
- Deactivate and detach the iSCSI domain from the local data center, attach and activate it in the shared data center and register its VMs.

Unfortunately the source environment is placed in a different site and I cannot connect a "fast" local domain to it: no internal disks and old blade system so that no fast USB channel
ALso, in the destination iSCSI I have many VMs running and I cannot it put it down.
I have to transfer 2 VMs for a total of about 500Gb of storage
