Actually I tried it and it worked well. The only issue was that I had to change the devices "SERVER" field to match the domain. After that all was good.
The trick to do that was to first rename the domain to the one you want. Starting from the top edit the extension. Then right click on the hyperlink to the device's mac address and chose open in new tab. That way you have both extension and device opened up.
Modify the server url in the devices and choose update. You can now close the devices tab. Click update to save the extension tab IF any changes have been made.
