I'm migrating a website from Prestashop 1.6 to Prestashop 1.7 and I need to add 301 redirects for product pages to htaccess. So the link structure is as follows:

Old website: https://example.com/lang/category-name/product-name.html

New website: https://example.com/lang/product-name.html

The website has around 70 categories in each language. What would be the best way to redirect URLs to the new link structure?

Thanks in advance.
