Upgrading from 1.6.1 to 1.6.2
*****************************

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/language

* system/libraries

Note:

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


Step 2: Encryption Key
======================

If you are using sessions, open up application/config/config.php and
verify you’ve set an encryption key.


Step 3: Constants File
======================

Copy /application/config/constants.php to your installation, and
modify if necessary.


Step 4: Mimes File
==================

Replace /application/config/mimes.php with the dowloaded version. If
you’ve added custom mime types, you’ll need to re-add them.


Step 5: Update your user guide
==============================

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