Open VPN cipher versions

Hi all,

I’m new here and to VyOS, I have a client who uses openvpn and is worried about older cipher versions that will soon stop working due to them being outdated, so my questions are:

  1. How can i confirm what current versions they’re using?
  2. How can I safely update these?

I was thinking may be clone the VM and then safely run an update on the clone first?

Thanks
Z
