Migrate OpenVPN server from 9.4 to 12

Running into issues with Untangle 12 OpenVPN clients disconnecting, when connected to Untangle 9.4 server (see here: https://forums.untangle.com/installa...ngle-12-a.html). So, looking to upgrade the Untangle OpenVPN server to version 12. Is there a way to migrate the OpenVPN settings, with all of the server and client and network info, keys, etc etc? Or do I have to start from scratch and create a whole new OpenVPN server setup, create all of the clients again and then distribute all of the clients (i.e. nightmare)....? I couldn't find any clear documentation on this, but I could be looking in the wrong place.

I tried simply copying the contents from /etc/openvpn, but nothing shows up when I go into the OpenVPN settings in the default rack....

Thx.
Marty.
