<h1 id="upgrade-and-migration">Upgrade and migration</h1>
<h2 id="preparation">Preparation</h2>
<h3 id="backup-your-data">Backup your data</h3>
<p>Shaarli stores all user data under the <code>data</code> directory:</p>
<ul>
<li><code>data/config.php</code> - main configuration file</li>
<li><code>data/datastore.php</code> - bookmarked links</li>
<li><code>data/ipbans.php</code> - banned IP addresses</li>
</ul>
<p>See <a href="Shaarli-configuration.html">Shaarli configuration</a> for more information about Shaarli resources.</p>
<p>It is recommended to backup this repository <em>before</em> starting updating/upgrading Shaarli:</p>
<ul>
<li>users with SSH access: copy or archive the directory to a temporary location</li>
<li>users with FTP access: download a local copy of your Shaarli installation using your favourite client</li>
</ul>
<h3 id="migrating-data-from-a-previous-installation">Migrating data from a previous installation</h3>
<p>As all user data is kept under <code>data</code>, this is the only directory you need to worry about when migrating to a new installation, which corresponds to the following steps:</p>
<ul>
<li>backup the <code>data</code> directory</li>
<li>install or update Shaarli:
<ul>
<li>fresh installation - see <a href="Download-and-installation.html">Download and installation</a></li>
<li>update - see the following sections</li>
</ul></li>
<li>check or restore the <code>data</code> directory</li>
</ul>
<h2 id="upgrading-from-release-archives">Upgrading from release archives</h2>
<p>All tagged revisions can be downloaded as tarballs or ZIP archives from the <a href="https://github.com/shaarli/Shaarli/releases">releases</a> page.<a href=".html"></a></p>
<p>We <em>recommend</em> using the releases from the <code>stable</code> branch, which are available as:</p>
<ul>
<li>gzipped tarball - <a href="https://github.com/shaarli/Shaarli/archive/stable.tar.gz" class="uri">https://github.com/shaarli/Shaarli/archive/stable.tar.gz</a></li>
<li>ZIP archive - <a href="https://github.com/shaarli/Shaarli/archive/stable.zip" class="uri">https://github.com/shaarli/Shaarli/archive/stable.zip</a></li>
</ul>
<p>Once downloaded, extract the archive locally and update your remote installation (e.g. via FTP) -be sure you keep the contents of the <code>data</code> directory!</p>
<p>After upgrading, access your fresh Shaarli installation from a web browser; the configuration will then be automatically updated, and new settings added to <code>data/config.php</code> (see <a href="Shaarli-configuration.html">Shaarli configuration</a> for more details).</p>
<h2 id="upgrading-with-git">Upgrading with Git</h2>
<h3 id="updating-a-community-shaarli">Updating a community Shaarli</h3>
<p>If you have installed Shaarli from the <a href="Download#clone-with-git-recommended">community Git repository</a>, simply <a href="https://www.git-scm.com/docs/git-pull">pull new changes</a> from your local clone:<a href=".html"></a></p>

<h3 id="migrating-and-upgrading-from-sebsauvages-repository">Migrating and upgrading from Sebsauvage's repository</h3>
<p>If you have installed Shaarli from <a href="https://github.com/sebsauvage/Shaarli">Sebsauvage's original Git repository</a>, you can use <a href="https://git-scm.com/book/en/v2/Git-Basics-Working-with-Remotes">Git remotes</a> to update your working copy.<a href=".html"></a></p>
<p>The following guide assumes that:</p>
<ul>
<li>you have a basic knowledge of Git <a href="https://git-scm.com/book/en/v2/Git-Branching-Branches-in-a-Nutshell">branching</a> and <a href="https://git-scm.com/book/en/v2/Git-Basics-Working-with-Remotes">remote repositories</a><a href=".html"></a></li>
<li>the default remote is named <code>origin</code> and points to Sebsauvage's repository</li>
<li>the current branch is <code>master</code>
<ul>
<li>if you have personal branches containing customizations, you will need to <a href="https://git-scm.com/book/en/v2/Git-Branching-Rebasing">rebase them</a> after the upgrade; beware though, a lot of changes have been made since the community fork has been created, so things are very likely to break<embed src=".html" /></li>
</ul></li>
<li>the working copy is clean:
<ul>
<li>no versioned file has been locally modified</li>
<li>no untracked files are present</li>
</ul></li>
</ul>
