Dear Sir,

How can I upgrade opencart from 1.5.5.1 to 3.0.2.0?

Can I use some import/export csv or excel tools if we cannot direct upgrade database?

Best Regard
Kitty

It would rather be best seek professional assistance or to implement the values in the database from a scratch installation if you can troubleshoot the error messages being displayed on screen. However, always make a backup of your entire store and database and to test those upgrades on a test environment server or on a virtual server.

Hi,

You can use below extension to migrate your data from 1.5.5.1 to 3.0.2.0

For Theme better to contact with professional Design/Developer to make changes to make theme compatible with 3.0.2.0

While the provided extension may include many features, it does not handle new SQL fields that needs to be created upon upgrade operations. This extension is not a between-version operation but rather a compatibility of those versions that can be used. Also take note that the demo of this site provides an example XLS file but results corrupted header file with OpenOffice.

The extension above does not indicate screenshots, feedbacks or comments regarding the succession of the affiliate transfers over the customers table which is where most of the users fails to originally complete the upgrade process from the core.

Honestly to avoid issues you need assistance in making your lower version to higher.
