The main constarints for Enhanced vmotion is the Layer 2 Network and same CPu model and can only be done through webclient.But the thing that got to my mind is if vmotion is non routable as of 5.1 then how enhanced vmotion is making to move live machines migrated over to different clusters?.
Because we had 5.1 ESxi's in Vsphere 5.1 , we use VLAN 199 for vmotion, so if we use dvswitch 5.1 for all the clusters in the vcenter , do the vmotion get affected accross hosts/or accross clusters?..
