Static Mac adress on guest machine

Hi All,

I must convert a Windows 7 machine from VMware to a Hyper-V Cluster. But the Problem is that we Need to Keep the old MAC Adress on this Client after conversion. How can I do this?

From my understanding means static IP in Hyper-V only that always the same MAC Adress will be assigned to the guest from the pool.

But ist very important for us to keep the old one ...

Hope someone has an idea here ...

Many thanks
