4.1. General instructions¶
Suricata can be upgraded by simply installing the new version to the same
locations as the already installed version. When installing from source,
this means passing the same
--datadir options to
$ suricata --build-info|grep -A 3 '\-\-prefix' --prefix /usr --sysconfdir /etc --localstatedir /var --datarootdir /usr/share
4.1.1. Configuration Updates¶
New versions of Suricata will occasionally include updated config files:
reference.config. Since the Suricata
installation will not overwrite these if they exist, they must be manually
updated. If there are no local modifications they can simply be overwritten
by the ones Suricata supplies.
Major updates include new features, new default settings and often also remove features.
