Migrate VM to Different vCenter but retain same MAC address

Hi

I'm working on a large VM migration project that mainly entails using DELL Appassure to image the VM, transfer to different city, then export into the vCenter there.

On a few VM servers we have software that is licensed by MAC address and would like to retain the same MAC after migration as it had before so we don't have to re-license the software.

Does vCenter holistically maintain the same MAC, or as I suspect when it gets imported into the new vCenter it gets a new MAC address?

Is there a way to change the MAC address on the virtual NIC after it is imported to make it the same value?

Would 2003 or 2008 freak out if the MAC address was changed to a NIC it thinks is already there, but not being used?

Thank you!

Tony

The MAC Address should remain in the Configuration File (VMX) of the Virtual Machine.

Yes, if you Right Click the VM, Click Edit Settings, Select the VM Network Interface, you can select MANUAL, and RE-INPUT the MAC Address.
