What to do after pagination to loader

Hello guys,

I am working on a website it has pagination. Now we have decided to move on to loader. I want to know if it is fine. should I redirect the pages (like page/2/), page/3/) to the main page after loader implementation?

Please share your experience. I have never done this before.
