I'm not sure why you can't see get running reconfig, log bundle will be useful for investigation, but seems that all things you want to do could be done without Converter: new SID, remove from domain, new network card.
Just to clarify: the network card's MAC address is never preserved during conversion, so you can just remove the static IP from card and lease a new IP, otherwise - go to VM's settings remove existing network card and add new one.
