SCVMM 08 VLAN ID migration error

hi

I have 29 VM with Hyper-V.
I am changing some of them with SCVMM08 migrate option.
The source server doest have a trunk.
The target server has a trunk.
If I migrate a VM without Vlan id to another server without vlan id, I dont have any problem. The migrate wizard inside SCVMM07 runs well.
If I migrate a VM withou VLAN ID to another server with VLAN ID, I have a problem.
The VM migrate, but I need to assign the VLAN ID by hand.
Is there any option to do that with SCVMM08?

I dont know. ;-(
