React to Next.JS porting

we have a project involves porting React to NextJS, we use dynamic routing on client side which needs to be ported also page consists of components which re built dynamically as well, which needs to be rendered in server side using nextjs as well.

We only want expert NextJS resource who can see our existing code and port few dynamic pages ported to nextJS

We also want to both nextjs and react projects to coexist in same domain, as dashboard still can be based out of React.
