Hi,
You can click on the "export" button of the products listing and you'll get a CSV of the products and then you can import it via the menu products>Import in your new website.
You'll also have to copy the images from the upload folder of your old website to your new website via FTP.
For the product data, you also also alternatively export/import the tables hikashop_product hikashop_related hikashop_file hikashop_category hikashop_product_category hikashop_variant hikashop_price hikashop_variant via your PHPMyAdmin and that will do it as well.
