Need help with ps 1.4.6.2 to 1.5.0.14

[Archon]

Hello. I have a prestashop 1.4.6.2 live shop (made a clone of the site on a test server) and i want to upgrade to 1.5.0.14 . My problem is that on the 1.4.6.2 server i have modified the core files (not that much) only added some new text fields on registration area and on the pdf invoice (think it's not that big of a deal). Can someone tell me how i upgrade without loosing my customers/products/categories ? That's all i care products and customers(users) that registered.

 

Please if someone has an ideea i would be gratefull.

 

Best regards,

Florin

Hi mike and thanks for the reply. I tried this link http://doc.prestashop.com/display/PS15/Manual+update+(experts+only) to make the upgrade but i get the error 34 and alot of errors regarding the translation of the back end. I will try another time to upgrade using the link you provided. Hope it will help but if it doesn't help ill post it here. I want to mention that when i received the error 34 the back-end was semi functional. I had the products from the old store and the categories but lots of bad code in-between.

 

I'll come up with a new answer in a couple of hours if this works or not.

 

Best regards,

Florin

Hi Mike. It doesn't work. I still get the error 34 regarding some translations (alot of errors appear on the back-end regarding translations). Don't know what to do. Can you give me some hints or advice or any other ideea how i might solve my problem ? i just need the products/customers/categories from the old database (1.4.6.2) to import it to 1.5.0.14 that's it. No orders no other stuff

 

Best regards,
