Adding new MAC Address range?

Hi,

I'm migrating / cloning license servers from Hyper-V to VMware, The current hyper-V MAC Addresses are not within the range and cannot be used.

Adding the mac address in the Operating System is not working.

I know that within SCVVM it's possible to add a MAC Address range, is this also possible in vCenter 6 or on the host?

Thanks in advance,

Kind regards,

Dennis
