Hyper-V 2 VMware keep mac address

Hi,

At this moment I'm busy to migrate servers from Hyper-V to a VMware cluster, this is no problem with the vCenter standalone software, untill now 40 succesfull migrations.

For the next migrations, License servers, I need to keep the MAC Address intact on the Virtual Server, after 2 failed clone /migrations and googling this I did get little bit confused on all the different kind of tools and software available.

Are there any tools / software to clone Virtual machines and keep the MAC Address the same.

Thanks in advance,

Dennis
