I am trying to upgrade my shop running from PS1.3.2.3 to latest version 1.4.8.2. I have tried several times as per http://doc.prestashop.com/display/PS14/Updating+PrestaShop
I have replaced Mail, Img, Modules, Themes, Upload and Download folders with old version files also changed the setting file in Config Folder. But I don't know if any
added customized Classes in old version as the guy who did the site is not contactable any more.
Can I get the site up and running without adding any customized Classes
How do I find customized Classes files in old version
Is this problem due to any other thing like Modules, Themes etc
Your help is appreciated.
