I want to migrate a complex React app built with CRA to the latest Next.js 13. I checked online but I don't find any helpful resources. Even official Next.js docs has content only related to [Vite](https://nextjs.org/docs/app/building-your-application/upgrading/from-vite).

I am trying the Vite doc and facing issues regarding incompatibility with MUI. Now I am first upgrading MUI to v5 but still would love any help.
