Proper Path To Keep Using ISC-DHCP

[House Of Cards]

Hello,

My recent upgrade failed, and I suspect that the ISC-DHCP plugin may have been the issue.  I had connectivity problems, and I want to try again.

I have a backup of my 25.7 configuration.  Should I install 26.1 fresh and recover the config during install, then run 'pkg install os-isc-dhcp' to make sure the configuration carries over?  Or should I install clean, install the plugin, then restore the configuration?

If that package doesn't install, I suspect that is where my issue arises.
