🔁 Step-by-Step Migration from Docusaurus v1 → v2

1. 📦 Install Docusaurus v2

bashCopyEditnpm install --save @docusaurus/core@latest @docusaurus/preset-classic@latest

Or if using Yarn:

bashCopyEdityarn add @docusaurus/core@latest @docusaurus/preset-classic@latest

---

2. 📁 Rename siteConfig.js to docusaurus.config.js

Then start adapting its contents. For example:

v1:

jsCopyEditconst siteConfig = {
  title: 'My Site',
  tagline: 'The tagline',
  ...
};

v2:

jsCopyEditmodule.exports = {
  title: 'My Site',
  tagline: 'The tagline',
  url: 'https://yoursite.com',
  baseUrl: '/',
  ...
}

3. 🧹 Remove pages/ and use /src/pages

Docusaurus v2 uses src/pages for your custom React pages.

You can convert Markdown docs to use the docs/ folder and React pages into src/pages.

---

4. 📑 Move docs/, update sidebar

• Keep your Markdown files under /docs.

• Create a sidebars.js file for navigation:

jsCopyEditmodule.exports = {
  docs: [
    {
      type: 'category',
      label: 'Getting Started',
      items: ['intro', 'installation'],
    },
  ],
};

---

5. 🎨 Update custom styling

• Put custom CSS into src/css/custom.css.

• Add it to your config:

jsCopyEdittheme: {
  customCss: require.resolve('./src/css/custom.css'),
},

---

6. ✨ Use Presets

In docusaurus.config.js, use the @docusaurus/preset-classic preset to enable docs/blog/theme:

jsCopyEditpresets: [
  [
    '@docusaurus/preset-classic',
    {
      docs: {
        sidebarPath: require.resolve('./sidebars.js'),
        editUrl: 'https://github.com/your-org/repo/edit/main/docs/',
      },
      theme: {
        customCss: require.resolve('./src/css/custom.css'),
      },
    },
  ],
],

---

7. 🖼 Update Images and Assets

Move static assets like logos, favicons, etc. into /static.

bashCopyEdit/static/img/...

Access them in code like /img/logo.svg.

---

8. 🧪 Test Locally

bashCopyEditnpx docusaurus start

This runs your site at http://localhost:3000

---

🧰 Optional: Use Migration Tool

There's a v1 to v2 migration tool to help convert common config:

bashCopyEditnpx @docusaurus/migrate

Run it inside your existing Docusaurus v1 project.
