# CodeIgniter User Guide Version 2.1.0

Search User Guide

# Upgrading from 1.5.4 to 1.6.0

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

## Step 1: Update your CodeIgniter files

Replace these files and directories in your "system" folder with the new versions:

- system/codeigniter
- system/database
- system/helpers
- system/libraries
- system/plugins
- system/language

Note: If you have any custom developed files in these folders please make copies of them first.

## Step 2: Add time_to_update to your config.php

Add the following to application/config/config.php with the other session configuration options

`$config['sess_time_to_update'] = 300;`

## Step 3: Add $autoload['model']

Add the following to application/config/autoload.php

`/*
| -------------------------------------------------------------------
| Auto-load Model files
| -------------------------------------------------------------------
| Prototype:
|
| $autoload['model'] = array('my_model');
|
*/
$autoload['model'] = array();`

## Step 4: Add to your database.php

Make the following changes to your application/config/database.php file:

Add the following variable above the database configuration options, with $active_group

`$active_record = TRUE;`

Remove the following from your database configuration options

`$db['default']['active_r'] = TRUE;`

Add the following to your database configuration options

`$db['default']['char_set'] = "utf8";
$db['default']['dbcollat'] = "utf8_general_ci";`

## Step 5: Update your user guide

Please also replace your local copy of the user guide with the new version.
