Hi,
I've started working on an unofficial script to convert legacy IPsec configurations to new IPsec Connections:
https://github.com/fraenki/opnsense-ipsec-converter
It will probably not work on complex configurations, but it may be a good starting point for some.
I can't spend much time on improving it, but I'll gladly review any PR. :)
Please don't ask the OPNsense developers for support when using this script. Thanks!
Ciao
