This is a Perl script I wrote and used for the migration of a linux DHCP server (running dhcpd to a Windows DHCP server. The script looks in the dhcpd.conf configuration file for fixed reservations and exports these to a CSV for processing and importing in another server.

Usage is simple, as it takes its input from STDIN and outputs to STDOUT.

cat /etc/dhcpd.conf | perl export-dhcpd-reservations.pl > output.csv

The script is very simple and can probably do with a lot of improvements, but it's a start for anyone willing to develop it further. It is licensed as GPLv3.
