redirect old index.php url to new permalink

Hi.

I am working for my clients blog and initially the blog URL structure is like below (the OLD URL):

https://www.mywebsite.com/WordPressBlog/index.php/category-name/post-name/

Now the URL has been changed to below

https://www.mywebsite.com/WordPressBlog/post-name/

Now if I open the OLD URL then it shows No Input Specified Error with 404 Not Found Status Code.

Please guide me on how redirect OLD urls to the New One.

Thanks and regards !
