Upgrade Host 10 to 12, LAN only to All connections

Hello there. We have a GPO that deploy a custom teamviewer Host 10 with the "accept LAN only connections" enabled. Now we bought a TV12 licence, so we want to upgrade. What is the best way to upgrade to a custom Tv 12 Host (already created) with the "Accept all connections" enabled, and also auto assigned to our account (so we can manage them in the TV Console Management"?
