Yes, I have done with a test VM, but I can't do it with production VMs because if I remove vlan tag, the source VM will stop to work.
But I can install and configure SDN on the source cluster (upgrading it to the last 8.x), create a vlan zone, a vnet with that vlan id, change source bridge to vnet bridge and removing the vlan tag, and migrate. (I have just tested and seems to work).

Thank you again, Fabrizio
