I think the best for you will be to read "The systemd for
Administrators Blog Series", which is a section at
http://www.freedesktop.org/wiki/Software/systemd/

It explains for example how to convert a sysv init script to a systemd
service file, what are the changes regarding configuration files with
systemd, how to improve the security of your services, analyze the
startup,... It will help for the transition from sysv to systemd.
