60 <p>Before performing an update you should take your site offline by replacing the index.php file with a static one.</p>

73 <li><dfn>system/libraries</dfn></li>
74 <li><dfn>system/plugins</dfn></li>
75 <li><dfn>system/language</dfn></li>
78 <p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>
80 <h2>Step 2: Add time_to_update to your config.php </h2>
81 <p>Add the following to application/config/config.php with the other session configuration options</p>
82 <p><code>$config['sess_time_to_update'] = 300;</code></p>
83 <h2>Step 3: Add $autoload['model']</h2>
84 <p>Add the following to application/config/autoload.php</p>
86 | -------------------------------------------------------------------<br />
87 | Auto-load Model files<br />
88 | -------------------------------------------------------------------<br />
91 | $autoload['model'] = array('my_model');<br />
95 $autoload['model'] = array();</code></p>
96 <h2>Step 4: Add to your database.php </h2>
97 <p>Make the following changes to your application/config/database.php file:</p>
98 <p>Add the following variable above the database configuration options, with <dfn>$active_group</dfn></p>
99 <p><code>$active_record = TRUE;</code></p>
100 <p>Remove the following from your database configuration options</p>
101 <p><code>$db['default']['active_r'] = TRUE;</code></p>
102 <p>Add the following to your database configuration options</p>
103 <p><code>$db['default']['char_set'] = "utf8";<br />
104 $db['default']['dbcollat'] = "utf8_general_ci";</code></p>
106 <h2>Step 5: Update your user guide</h2>
107 <p>Please also replace your local copy of the user guide with the new version.</p>
