I need to migrate a VM to a new ESXi host. The VM hosts software which has a license key tied to the MAC address . The new license key will take 24 hours re-generate - the software cannot be offline that long..
The advice from the Vendor is to replicate the VM to the new host, power-down the existing VM, power-on new VM to get the new 'RegCode' to submit for license generation. Then reverse.
Once the new license code has been generated - power-up the new replicate, enter the new license code..
Is there a way to power-up the replicated VM to get the 'RegCode' without having to power-down the live VM to avoid IP conflicts? The new host is connected to the same networks and several VM's are make use of the NICS.
