Hello, ive moved my shop from prestashop 1.6 to 8.2 and all my brands url (manufacturers_ have underscores. i tried to editing this is url rewrite and set a dash instead of the underscore for manufacturers link rewrite, thinking it will automatically redirect to 301. but unfortunately, they were all 404.. any solution? thank you.
