I am currently using version 1.4.4 of opencart and would like it upgrading to the latest version of 1.5.2 keeping all the orders and customer information etc in the admin panel.
I have seen and upgrade script http://forum.opencart.com/viewtopic.php?f=2& t=36519 which will upgrade to version 1.5.
I would also like to keep as much of the template design as possible and for the seo module to be switched on.
Kind Regards,
Laura
