To start this tutorial be sure to have the version 3.1 of the tao platform. You can see your version at bottom left of the screen
If you don't have a tao platform version 3.1 running please have a look to [installation guide](../../forge/Installation and Upgrading/installubuntuapachemysql)
Download the release 3.2 here and unzip it
Copy files from the newly downloaded release 3.2 to the directory where is stored the release 3.1 on your server. You should replace everything except data and config directories. Make sure that the user that will access the directories (www-data) have the rights on them.
On your web server launch the command
sudo -u www-data php tao/scripts/taoUpdate.php
You should now see something like the following image.
