You could upgrade your current installation by following our installation guide.
Once the package is installed, review your
/var/ossec/etc/ossec.conffile, as it will be overwritten. The one that was previously in use has been saved as

A backup of your custom rules and decoders will be saved at
/var/ossec/etc/backup_ruleset. You need to reapply them again, we recommend use
/var/ossec/etc/rulesfor custom rules and decoders, these directories won’t be overwritten by future upgrades.
