Hello!
I think that the easiest way of achieving this is to simply rename your folders in your Next.js application. Instead of having pages/article and pages/category you would have pages/section and pages/room then you’ll need to modify the internal code to get rid of your Next.js article and category logic (the pages) but keeping the requests you make with Strapi the same (/articles and /categories).
Here I consider that you only want to change article and category on the front, not in Strapi. If you want to change it in Strapi, then you would need to simply change your collection type and then your Next.js code accordingly.
