Add migration guide from Create React App

[leerob]

Feature request

As a user of [x] framework/language, I'd love to see an easy path towards migrating to Next.js

Describe the solution you'd like

Documentation around common providers and how exactly you can switch to Next.js from them.

Hello! I would like to work on this issue, but I'm not sure what should be the final product? I found this very helpful guide, would it be something like this?

[leerob]

Hey @PeppermintNDaisies! This isn't very well defined, yet, but you could convert the standard npx create-react-app template over to Next.js and then add the PR here so we can see the diff 🙏

[peppermint-juli]

Will do! Where should I place the result? In the examples folder?

[leerob]

Could you leave it as a comment here? This issue will get turn into documentation eventually 👌

[peppermint-juli]

Okay sure! Like a step by step then

[leerob]

@PeppermintNDaisies Yeah, here's similar docs for migrating from Gatsby -> #17491

[peppermint-juli]

Perfect! I'll give them a look

[peppermint-juli]

@leerob I used your Migration guide from Gatsby as a guide, do you think this is a good start?

[leerob]

We shouldn't create documentation – yet. As mentioned previously, the first step is creating an example that converts npx create-react-app to Next. It would also be helpful to understand if there's an easy path for migrating an ejected CRA configuration. This research needs to happen first before docs are created 🙏

[leerob]

Heads up – I removed "good first issue" as this isn't well defined yet.
