<h3 id="note-your-current-version">Note your current version</h3>
<p>If anything goes wrong, it's important for us to know which version you're upgrading from.<br />
The current version is present in the <code>version.php</code> file.</p>
<h3 id="backup-your-data">Backup your data</h3>
<p>Shaarli stores all user data under the <code>data</code> directory:
- <code>data/config.php</code> - main configuration file
- <code>data/datastore.php</code> - bookmarked links
- <code>data/ipbans.php</code> - banned IP addresses
- <code>data/updates.txt</code> - contains all automatic update to the configuration and datastore files already run</p>
<p>See <a href="../Shaarli configuration">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:
- users with SSH access: copy or archive the directory to a temporary location
- users with FTP access: download a local copy of your Shaarli installation using your favourite client</p>
<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">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="recommended-upgrading-from-release-archives">Recommended : 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.</p>
<p>We recommend that you use the latest release tarball with the <code>-full</code> suffix. It contains the dependencies, please read <a href="../Download and installation">Download and installation</a> for <code>git</code> complete instructions.</p>
<p>Once downloaded, extract the archive locally and update your remote installation (e.g. via FTP) -be sure you keep the content of the <code>data</code> directory!</p>
<p>After upgrading, access your fresh Shaarli installation from a web browser; the configuration and data store will then be automatically updated, and new settings added to <code>data/config.json.php</code> (see <a href="../Shaarli configuration">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:</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.</p>
<p>The following guide assumes that:
- 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>
- the default remote is named <code>origin</code> and points to Sebsauvage's repository
- the current branch is <code>master</code>
    - 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!
- the working copy is clean:
    - no versioned file has been locally modified
    - no untracked files are present</p>
