# Overview ::alert{type=info} This migration guide is under progress to align with the development of Nuxt 3. :: Nuxt 3 is a complete rewrite of Nuxt 2, and also based on a new set of underlying technologies. That means there will be significant changes when migrating a Nuxt 2 app to Nuxt 3, although you can expect migration to become more straightforward as we move toward a stable release. Some of these significant changes include: 1. Moving from Vue 2 to Vue 3, including defaulting to the Composition API and script setup. 1. Moving from webpack 4 and Babel to Vite or webpack 5 and esbuild. 1. Moving from a runtime Nuxt dependency to a minimal, standalone server compiled with nitropack. ::alert{type=info} If you need to remain on Nuxt 2, but want to benefit from Nuxt 3 features in Nuxt 2, you can alternatively check out [how to get started with Bridge](/getting-started/bridge). ::
