> Learn how to migrate from Nuxt 2 to Nuxt 3 server.

## Steps

1. Remove the `render` key in your `nuxt.config`.
2. Any files in `~~/server/api` and `~~/server/middleware` will be automatically registered; you can remove them from your `serverMiddleware` array.
3. Update any other items in your `serverMiddleware` array to point to files or npm packages directly, rather than using inline functions.
