Editing OpenVPN server settings after installation

[MrCatEsq]

I am using openvpn-install.sh script for the automatic installation of an OpenVPN server, and I have some questions regarding editing the settings after installation.

1. How should I properly edit the OpenVPN server settings after installation using the script? Can I just edit /etc/openvpn/server.conf, or is there a special tool for this?

2. Do I need to recreate users using openvpn-install.sh after every change in the server settings? For example, I want to change the server protocol from TCP to UDP. Is it enough to just replace proto tcp with proto udp in config file and restart the OpenVPN service (daemon), or is there anything else I should do?
