I've had OpnSense for years, but might move to new hardware. Over those years I've tried and failed many, many, times to get my configuration imported at install time.
Daily, I don't live in the *nix world. My desktops are Windows or Mac.
What format of, say, a USB flash drive is OpnSense expecting to find that contains my config? Is there a formatter for Mac/Windows that I can use as well as a tool to copy the config onto it?
Thanks for any advice!
