# Migration

# Migrate from default theme

Since VT is fully compatible with VuePress's Default Theme (opens new window), migrating from default theme to VT is very easy:

 // .vuepress/config.js
 module.exports = {
+  theme: 'vt',
   themeConfig: {

We have migrated VuePress's documentation to VT at #21 (opens new window) with super minimal code changes, you can preview at vuepress-docs.vercel.app (opens new window).

# Migrate from other themes

First, you need to make sure you are not overly relying on the theme's features. Second, you can migrate based on Getting Started > Manual Installation, if you encounter any issues or features that need to be added, feel free to submit an issue (opens new window) or pull request (opens new window).
