############################# 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.
