How to update a MAC address of a VM using Orchestrator

Hi,

I am trying to update the MAC address of a virtual NIC using an orchestrator workflow. I have found ways to get the MAC address and put it into arrays and the like, but i am struggling to actually be able to update the MAC address on the VM itself. I am trying to create a workflow that will allow me to set the MAC address to manual within a vNIC and set the MAC address.

Any tips or pointers in the right direction would me most appreciated.

thanks in advance

Dominic
