How to upgrade/update PrestaShop 1.3.1 to 1.3.3

[grasnal]

Hi all! Can someone guide me with process of updating PrestaShop from 1.3.1 to 1.3.3? I followed >> this guide << but after firing up installation installer didn't recognize old installation providing me only option to make fresh installation and at the next step asked me to remove old database when I defined access data to it.

Appreciate any help.
Best regards.

You are doing right, the guide works! Maybe you have missed a step? Have you copied the setting.inc.php before starting the update? If not the installer will not recognize that you are updating from an older version. This file contains the information of what version you use.
(check the version the last line in the file:)

If doing it correctly, the update radio button should be on. Check your setting.inc.php file again to make sure all the path and description are correct.

The installation program will check e version number in the settings.Inc.php if e new version is higher it will proceed with upgrading
