Restore Zentyal 3.3 OpenVPN Configuration to Zentyal 3.5

[Lonniebiz]

From Zentyal 3.0 to 3.3.10, version upgrades predominantly succeeded in the Community edition.

Since 3.3.10, I have not been able to succeed in upgrading to 3.4 or 3.5.

I've also attempted installing 3.5 fresh, and restoring the 3.3.10 configuration to it. This is not supported.

This particular Zentyal server is functioning as a Gateway and providing OPEN VPN. Would it be easy to back up and restore just the VPN module protion of Zentyal 3.3 to a freshly installed 3.5?

I'm trying to avoid creating new keys/cert/etc. for all clients.
