<p>During development there may be cases where the handling of bugfixes might touch the userspace. We try to avoid this as far as
possible but sometimes it is inevitable.</p>
<p><span class="bold"><strong>Normal Icinga update Path</strong></span></p>
<p>If there's a new Icinga version available on <a class="link" href="http://www.icinga.org/" target="_top">https://www.icinga.com/</a> you should
consider updating. Newer versions contain bugfixes, minor or major, which makes it even more important to get the latest and the
greatest. If you already installed Icinga using the quickstart guides it's rather easy to install newer versions. It's also
possible to perform that without root privileges by doing an install from source. It highly depends on your likings.</p>
<p>Make sure you'll have a safe backup of your Icinga installation and configs. If anything goes wrong you can restore your
old setup rather easy.</p>
<p>Regular updates of Icinga are possible just by re-installing Icinga. Please keep in mind that <code class="code">configure</code>
requires the same parameters as before - look it up in <code class="filename">config.log</code> and store that in a safe location.</p>
<p>Become the icinga user. Debian/Ubuntu users might use <code class="code">sudo -s icinga</code>. </p>
<pre class="programlisting"> $> su -l icinga</pre>
<p>Get
the latest Icinga version from <a class="link" href="http://www.icinga.org/" target="_top">https://www.icinga.com/</a> and extract it. Then run configure like you
did with the old version. </p>
<pre class="programlisting"> #> ./configure --with-command-group=icinga-cmd</pre>

<p><span class="bold"><strong>Icinga 0.8.0 to Icinga 1.14</strong></span></p>
<p><span class="emphasis"><em>Archived Logfilename</em></span></p>
<p>There was a small misspelling bug in Icinga 0.8.0 resulting in archived logfile names beginning with a capital <span class="bold"><strong>"I"</strong></span> like in <span class="bold"><strong>'Icinga-$date'</strong></span>". This was fixed in version 0.8.1. and newer.</p>
<p>If you experience this problem then please use the following script to fix the file names</p>
<pre class="programlisting"> #> cd /usr/local/icinga/var/archives

<p>Starting with Apache 2.4 the default web configuration folder changed from <code class="filename">/etc/apache2/conf.d</code> to

reload the web server: </p>

<p>We try to be compatible with the configuration files of the current Nagios 3.x versions so there should be very little you
have to do to "upgrade" from Nagios 3.x to Icinga 1.14. Assuming you've already installed Nagios from
source code as described in the Nagios quickstart guide, you can install Icinga quite easily.</p>
<p>If you are upgrading from Nagios 3.0.x you might need to install PHP:</p>
<p><span class="emphasis"><em>Debian / Ubuntu</em></span> </p>
<pre class="screen"> #> apt-get install php5 libapache2-mod-php5</pre>
<p><span class="emphasis"><em>Fedora / RedHat</em></span></p>
<pre class="screen"> #> yum install php mod_php</pre>
<p><span class="emphasis"><em>openSuSE / SLES</em></span></p>
<p>Use Yast to install the packages <span class="emphasis"><em>php5</em></span> and <span class="emphasis"><em>apache2-mod_php5</em></span> or use zypper</p>
<pre class="programlisting"> #> zypper install php5 apache2-mod_php5</pre>
<p>Make sure you have a good backup of your existing Nagios installation and configuration files. If anything goes wrong or
doesn't work, this will allow you to rollback to your old version.</p>
<p>Please install Icinga according to the <a class="link" href="quickstart.html" title="2.3. Quickstart Installation Guides">quickstart guide</a>. Please note that</p>
<div class="itemizedlist"><ul class="itemizedlist" type="disc">

<li class="listitem">

<p>PNP4Nagios is aware of that since 0.6rc1 (2009.09.20) but the macros are needed in "sync" mode only.</p>
<p>check_multi includes support since v0.21 (2010.06.03), but you have to rerun the installation using '<code class="code">configure

<p>It shouldn't be too difficult to upgrade from Nagios 2.x to Icinga 1.14. The upgrade is essentially the same
as what is described above for upgrading from Nagios 3.x releases. You will, however, have to change your configuration files a
bit so they work with Icinga 1.14:</p>
<div class="itemizedlist"><ul class="itemizedlist" type="disc">
<li class="listitem">
<p>The old <span class="emphasis"><em>service_reaper_frequency</em></span> variable in the main config file has been renamed to <a class="link" href="configmain.html#configmain-check_result_reaper_frequency">check_result_reaper_frequency</a>.</p>
</li>
<li class="listitem">
<p>The old <span class="emphasis"><em>$NOTIFICATIONNUMBER$</em></span> macro has been deprecated in favour of new <a class="link" href="macrolist.html#macrolist-hostnotificationnumber">$HOSTNOTIFICATIONNUMBER$</a> and <a class="link" href="macrolist.html#macrolist-servicenotificationnumber">$SERVICENOTIFICATIONNUMBER$</a> macros.</p>
</li>
<li class="listitem">
<p>The old <span class="emphasis"><em>parallelize</em></span> directive in service definitions is now deprecated and no longer used, as all service
checks are run in parallel.</p>
</li>
<li class="listitem">
<p>The old <span class="emphasis"><em>aggregate_status_updates</em></span> option has been removed. All status file updates are now aggregated at a
minimum interval of 1 second.</p>
</li>
<li class="listitem">
<p>Extended host and extended service definitions have been deprecated. They are still read and processed by Icinga, but
it is recommended that you move the directives found in these definitions to your host and service definitions, respectively.</p>
</li>
<li class="listitem">
<p>The old <span class="emphasis"><em>downtime_file</em></span> file variable in the main config file is no longer supported, as scheduled downtime
entries are now saved in the <a class="link" href="configmain.html#configmain-state_retention_file">retention file</a>. To preserve existing downtime
entries, stop Nagios 2.x and append the contents of your old downtime file to the retention file.</p>
</li>
<li class="listitem">
<p>The old <span class="emphasis"><em>comment_file</em></span> file variable in the main config file is no longer supported, as comments are now
saved in the <a class="link" href="configmain.html#configmain-state_retention_file">retention file</a>. To preserve existing comments, stop
Nagios 2.x and append the contents of your old comment file to the retention file.</p>
</li>
</ul></div>
<p>Also make sure to read the "<a class="link" href="whatsnew.html" title="1.2. What's New in Icinga 1.14">What's New</a>" section of the documentation. It describes all the changes
that were made to the Icinga code since the latest stable release of Nagios 3.0.6. Quite a bit has changed, so make sure
you read it over.</p>

<p>If you currently have an RPM- or Debian/Ubuntu APT package-based installation of Nagios and you would like to transition to
installing Icinga from the official source code distribution, here's the basic process you should follow:</p>
<div class="orderedlist"><ol class="orderedlist" type="1">

</li>
</ol></div>
<p>Note that different RPMs or APT packages may install Icinga in different ways and in different locations. Make sure you've
backed up all your critical Nagios files before removing the original RPM or APT package, so you can revert back if you encounter
problems.</p>
