I just finished upgrading Icinga from 0.8.4 to 1.0RC1 on an Ubuntu server. The upgrade was straight forward. I recommend you backup your /usr/local/icinga/etc directory prior to upgrading just in case something goes wrong.
Here are the steps I used to complete the upgrade in less than 5 minutes. Beginning in the directory where you downloaded the Icinga tarball:
$ sudo cp icinga-1.0-RC1.tar.gz /usr/src/
$ cd /usr/src
$ sudo tar xvfz icinga-1.0-RC1.tar.gz
$ cd icinga-1.0-RC1/
$ sudo ./configure
$ sudo make all
$ sudo make install
$ sudo /etc/init.d/icinga restart
This procedure assumes you already have a running installation of Icinga. Basically you only need to compile the new version and install the binaries, CGI scripts, and HTML files. Restart Icinga and you’re done!
