Upload Home License from CLI

Hi,

  Is it possible to upload a home license from the CLI?

  For family members, I built and admin a few Sophos UTM boxes (custom hardware, home licenses) - like, my parents and sister.  I usually have IPSec tunnels up.  I missed a license expiration for my parents, and unfortunately my parents are actually at my sister's...and wondering why they can't access certain things at home (IPsec tunnels usually link us all - they were saying "x" is down, but X is up...the tunnel is down!).

  I walked them through getting a new home license...but  they can't install it unless they go home, right?  Can I install it via CLI (I have SSH access).  The Webadmin is not exposed to the internet, only the LAN and other networks via IPSec tunnels (which are down).  Is the only thing I can do is wait until someone is on the LAN (I don't have a way to remotely access that network other than the UTM!).

  What happens if I reboot the UTM; will it switch to a trial license?  I just need the site to site VPN to come up, and then I can access the webadmin!

  Thanks for your help!
