Debian: How to upgrade MONIT correctly?

[address@hidden]

I did sudo apt-get install monit but it only installs version 5.9 and
the current version is 5.17.1. So I did

wget
https://mmonit.com/monit/dist/binary/5.17.1/monit-5.17.1-linux-x64.tar.gz

to download the precompiled binaries and now I have these files:

monit-5.17.1/bin/monit
monit-5.17.1/conf/monitrc
monit-5.17.1/man/man1/monit.1

I checked where MONIT is installed with "dpkg -S monit | sort":

monit: /etc/default/monit
monit: /etc/init.d/monit
monit: /etc/logrotate.d/monit
monit: /etc/monit

monit: /usr/share/lintian/overrides/monit
monit: /usr/share/man/man1/monit.1.gz
monit: /var/lib/monit
monit: /var/lib/monit/events

I know how to handle the conf-file monitrc but I don't know in which
paths I have to replace the file monit (only at /usr/bin/monit or
somewhere else?) and if this the correct way to upgrade at all.
