Using redux "just like in the past" won't work out of the box.

You need to setup redux beforehand with gatsby's SSR rendering, ie setup gatsby-browswer.js and gatsby-ssr.js.

To use redux in a Gatsby site you'll need to hook in to two of Gatsby's extension points.

Once in wrapRootElement which runs during Gatsby's server rendering process, and once in wrapRootElement which is part of Gatsby's browser APIs.

Check out ./gatsby-ssr.js and ./gatsby-browser.js to see how this is implemented in this example.

That's because the entry point you used to when booting with CRA is not the same entry point as in Gatsby.
