<h1>Upgrading from 1.6.1 to 1.6.2</h1>
<p>Before performing an update you should take your site offline by replacing the index.php file with a static one.</p>
<h2>Step 1: Update your CodeIgniter files</h2>
<p>Replace these files and directories in your "system" folder with the new versions:</p>
<ul>
<li><dfn>system/codeigniter</dfn></li>
<li><dfn>system/database</dfn></li>
<li><dfn>system/helpers</dfn></li>
<li><dfn>system/language</dfn></li>
<li><dfn>system/libraries</dfn></li>
</ul>
<p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>
<h2>Step 2: Encryption Key</h2>
<p>If you are using sessions, open up application/config/config.php and verify you've set an encryption key.</p>
<h2>Step 3: Constants File</h2>
<p>Copy /application/config/constants.php to your installation, and modify if necessary.</p>
<h2>Step 4: Mimes File</h2>
<p>Replace /application/config/mimes.php with the dowloaded version. If you've added custom mime types, you'll need to re-add them.</p>
<h2>Step 5: Update your user guide</h2>
<p>Please also replace your local copy of the user guide with the new version.</p>
