<p>Updating means updating ownCloud to the latest <em>point release</em>, e.g. ownCloud 4.0.6 → 4.0.7. To update an ownCloud installation manually, follow those steps:</p>
<div class="admonition note">
<p class="first admonition-title">Note</p>
<p class="last">If you have installed ownCloud from a repository, your package management should take care of it.</p>
</div>
<ol class="arabic simple">
<li>Make a backup.</li>
<li>Unpack the release tarball in the owncloud directory, i.e. copy all new files into the ownCloud installation.</li>
<li>Make sure that the file permissions are correct.</li>
<li>After the next page request the update procedures will run.</li>
</ol>
<p>Assuming your ownCloud installation is at <strong>./owncloud/</strong> and you want to update to the latest version, you could do the following:</p>
<p>Use rsync in archive mode (this leaves file owner, permissions, and time stamps untouched) to recursively copy all content from <strong>./owncloud/</strong> to a backup directory which contains the current date:</p>
<div class="highlight-python"><pre>rsync -a owncloud/ owncloud_bkp`date +"%Y%m%d"`/</pre>
</div>
<p>Download the latest version to the working directory:</p>
<div class="highlight-python"><pre>wget http://download.owncloud.org/community/owncloud-latest.tar.bz2</pre>
</div>
<p>Extract content of archive to <strong>./owncloud_latest/</strong>:</p>
<div class="highlight-python"><pre>mkdir owncloud_latest; tar -C owncloud_latest -xjf owncloud-latest.tar.bz2</pre>
</div>
<p>Use rsync to recursivly copy extracted files (new) to ownCloud installation (old) using modification times of the new files, but preserving owner and permissions of the old files:</p>
<div class="admonition warning">
<p class="first admonition-title">Warning</p>
<p class="last">You should not use this [–inplace] option to update files that are being accessed by others <em>(from rysnc man page)</em></p>
</div>
<div class="highlight-python"><pre>rsync --inplace -rtv owncloud_latest/owncloud/ owncloud/</pre>
</div>
<p>Clean up:</p>
<div class="highlight-python"><pre>rm -rf owncloud-latest.tar.bz2 owncloud_latest/</pre>
</div>
</div>
<div class="section" id="upgrade">
<h2>Upgrade<a class="headerlink" href="#upgrade" title="Permalink to this headline">¶</a></h2>
<p>Upgrade is to bring an ownCloud instance to a new <em>major release</em>, e.g.
ownCloud 4.0.7 → 4.5.0. Always do backups anyway.</p>
<p>To upgrade ownCloud, follow those steps:</p>
<ol class="arabic simple">
<li>Make sure that you ran the latest point release of the major ownCloud
version, e.g. 4.0.7 in the 4.0 series. If not, update to that version first
(see above).</li>
<li><strong>Make a backup of the ownCloud folder and the database</strong></li>
<li>Deactivate all third party applications.</li>
<li>Delete everything from your ownCloud installation directory, except data and
config.</li>
<li>Unpack the release tarball in the owncloud directory (or copy the
files thereto).</li>
<li>Make sure that the file permissions are correct.</li>
<li>With the next page request the update procedures will run.</li>
<li>If you had 3rd party applications, check if they provide versions compatible
with the new release.</li>
</ol>
<p>If so, install and enable them, update procedures will run if needed. 9. If
you installed ownCloud from a repository, your package management should take
care of it. Probably you will need to look for compatible third party
applications yourself. Always do backups anyway.</p>
