Whoa! Migrating to a new OS can be easy or it can your worse nightmare. Most people that run production environments do a lab-migration before migrating the production server.
Typically, I build a new server with the new OS and then migrate the applications over to the new OS step-by-step. After everything looks good, I cut the new server over to replace the old. Trying to migrate on a live server is asking for trouble because what ever can go wrong will (broken links, missing libs, permission problems, you name it).
However, simply rebuilding and upgrading a kernel or adding libs is usually OK (if you are CAREFUL and have a recovery plan).

I have some UFS volumes (non root), that I would like to change into ZFS volumes.

NAME
DenyHosts - version: 2.6
DESCRIPTION
DenyHosts is a python program that automatically blocks ssh attacks by adding entries to /etc/hosts.deny. DenyHosts will also inform Linux
administrators about offending hosts, attacked users and suspicious logins.
Usage: /usr/sbin/denyhosts [-f logfile | --file=logfile] [ -c configfile | --config=configfile] [-i | --ignore] [-n | --noemail] [--purge]
[--migrate] [--daemon] [--sync] [--version]
--file:
The name of log file to parse
--ignore: Ignore last processed offset (start processing from beginning)
--noemail: Do not send an email report
--unlock: if lockfile exists, remove it and run as normal
--migrate: migrate your HOSTS_DENY file so that it is suitable for --purge
--purge: expire entries older than your PURGE_DENY setting
--daemon: run DenyHosts in daemon mode
--foreground: run DenyHosts in foreground mode
--sync: run DenyHosts synchronization mode
--version: Prints the version of DenyHosts and exits
Note: multiple --file args can be processed. If multiple files are provided, --ignore is implied
Note: in a debian system, the default running mode is daemon mode and the configuration file is etc/denyhosts.conf
When run in --daemon mode the following flags are ignored:
--file, --purge, --migrate, --sync, --verbose
