The situation is as follows:
There is a store that was transferred to opencart about six months ago, and the owners apparently forgot about turning on the CNC. Now there is a task to include the CNC itself, but I, an inexperienced person in SEO, have a question: shouldn't the old URLs be removed from the search engine cache?

On the one hand, it was empirically discovered that with the "non-CNC" links you can go to the desired page, and a new, kosher CNC is displayed in the browser path bar. And losing, even if not the first, position in the issuance of the sovse-ee reluctance.

On the other hand, will the search engines, by the simplicity of their soul, perceive the appearance of a new path as duplication of content?

Yes, and in general I will be grateful for any advice on the site.

    Whatever, if you turn on the opencart2 cnc, there is no duplication of content, you need to close all the routes to which the cnc is applied in robots.txt. I'm not sure that this is the only right decision, but it works on our opencart projects.

    Disallow: /*?* Disallow: /*? Disallow: /*& Disallow: /*&*

    And, if we touched seo, I recommend to transfer the site to ssl.

      no, it’s not worth it, you make from all villages without a CPU 301 redirect to the CNC, the weight of the page is completely transferred to the CNC
