I have exported my products in an Excel spreadsheet file, and I then installed my products in a clean installation of OpenCart 184.108.40.206. Then I uploaded OpenCart 220.127.116.11 and ran the Upgrade script. The first time I ran the script, it went well even though it added some new lines in my config.php files.
Is there a way to export my products and categories, from my OpenCart 18.104.22.168 and import them directly in a OpenCart 22.214.171.124 installation?
I have some upgrading script in the extension store, but nothing worked really well.
