Migration Overview

The migration process has six main phases:

1. Planning - Audit your site, set goals

2. Content Export - Get your data out of WordPress

3. Design Rebuild - Recreate your look in React

4. Feature Replacement - Handle plugins and functionality

5. SEO Preservation - Maintain your rankings

6. Deployment - Go live on modern hosting

Let's cover each phase in detail.


Phase 1: Planning

Audit Your Current Site

Before migrating, document what you have:

Content Inventory:

  • [ ] Number of posts
  • [ ] Number of pages
  • [ ] Custom post types
  • [ ] Categories and tags
  • [ ] Authors
  • [ ] Media files (count and size)

Feature Inventory:

  • [ ] Active plugins and their purpose
  • [ ] Contact forms
  • [ ] E-commerce functionality
  • [ ] User accounts/memberships
  • [ ] Comments system
  • [ ] Search functionality
  • [ ] Multi-language support

Technical Details:

  • [ ] Current URL structure
  • [ ] Custom fields (ACF, etc.)
  • [ ] Custom theme modifications
  • [ ] Database size

Set Migration Goals

Define what success looks like:

  • Performance target: PageSpeed score of 90+
  • Timeline: 2-4 weeks typical for small sites
  • Budget: $0 (DIY) to $5,000+ (agency)
  • URL preservation: Keep same URLs for SEO

Phase 2: Content Export

Method 1: WordPress REST API (Recommended)

The REST API gives you structured access to all content:

// Fetch all posts

const response = await fetch('https://your-site.com/wp-json/wp/v2/posts?per_page=100');

const posts = await response.json();

// Each post contains:

// - title, content, excerpt

// - slug, date, modified

// - categories, tags

// - featured_media ID

// - author ID

Method 2: Built-in WordPress Export

1. Go to Tools → Export in WordPress admin

2. Select All content

3. Download the WXR (XML) file

This file can be parsed to extract content.

Method 3: Use Our Free Tool

LeaveWP Migration Tool automates the entire process:

1. Connect your WordPress site

2. Select what to migrate

3. Download Next.js-ready MDX files

No coding required for the export step.

Converting to MDX Format

Your content needs to become MDX files:

---

title: "Your Post Title"

date: "2026-01-15"

author: "Author Name"

excerpt: "Post excerpt here"

categories: ["Category 1", "Category 2"]

featuredImage: "/images/post-image.jpg"


Your Post Title

Your post content in Markdown...

!Alt text

Handling Media

Options for your media files:

1. Download and include: Host images with your site

2. Keep on WordPress: Use WordPress as image CDN (temporary)

3. Move to Cloudinary: Professional image hosting

4. Use Vercel Image: Built-in optimization

Recommended: Download images and use Next.js Image component for automatic optimization.


Phase 3: Design Rebuild

Start with a Template

Don't start from scratch. Use these as starting points:

  • Next.js Blog Starter: Official Next.js template
  • Taxonomy: Blog template with Tailwind
  • Chronark: Minimal blog template
  • Our LeaveWP templates: Pre-built themes

Core Layout Structure

A typical Next.js blog structure:

app/

├── page.tsx # Homepage

├── blog/

│ ├── page.tsx # Blog listing

│ └── [slug]/

│ └── page.tsx # Individual posts

├── about/

│ └── page.tsx # About page

├── contact/

│ └── page.tsx # Contact page

└── layout.tsx # Root layout with header/footer

Creating the Blog Post Page

// app/blog/[slug]/page.tsx

import { getPostBySlug, getAllPosts } from '@/lib/posts';

import { MDXContent } from '@/components/mdx-content';

export async function generateStaticParams() {

const posts = getAllPosts();

return posts.map((post) => ({

slug: post.slug,

}));

}

export default async function BlogPost({ params }: { params: { slug: string } }) {

const post = await getPostBySlug(params.slug);

return (

{post.title}

);

}

Styling Approaches

Option 1: Tailwind CSS (Recommended)

Option 2: CSS Modules

import styles from './blog-post.module.css';

Option 3: styled-components

const Article = styled.article

max-width: 65ch;

margin: 0 auto;

;


Phase 4: Feature Replacement

Contact Forms

WordPress: Contact Form 7, Gravity Forms, WPForms

Next.js Alternatives:

1. Formspree (Recommended for simplicity)
