How to Migrate WordPress to Strapi Headless CMS (With 1,000+ Posts)
Step-by-step guide to migrating a WordPress site with 1,000+ posts and media to a Strapi headless CMS using WPEscape, a purpose-built WordPress to Strapi migration tool.

My journey
I had multiple clients who owned WordPress websites that became harder and harder to maintain. I started helping them by providing Strapi CMS as a modern, secure and maintainable alternative.
Problems with WordPress can include increasing performance issues, security issues, a confusing admin panel due to thousands of plugins, and more. Since headless CMS systems like Strapi are growing, I have migrated entire WordPress sites to Strapi.
Can I build the migration myself
Yes, WordPress offers a REST API to get almost anything: posts, pages, media, menus, and more. You can see the complete list of APIs at WordPress REST API.
Why should I use your migration tool
I've packaged everything below into a product: WPEscape, a tool to migrate WordPress to Strapi (and other modern headless CMSs) without hand-rolling your own scripts.
Yes, you can build your own migration tool by fetching specific WordPress APIs, but there are some bottlenecks to consider:
Time effort
- I have spent months of research and development on this tool. You can save this time and focus on other features.
- You need to understand WordPress structure, including posts, custom post types, pages, menus, translations, and more.
- You need to set up Strapi CMS in a way that can be merged with your individual WordPress setup.
Other Problems with WordPress
WPML Translations
The pages/posts endpoint from WordPress only returns the standard language (the default language of your WordPress setup). To connect the WPML translation to the original page, you need to extend the WordPress REST API and migrate it into a Strapi translation model.
With the migration tool, you'll get a plugin that you can easily install in your WordPress setup to extend the API to include translation data. The translation data will then be read and migrated into a Strapi translation model.
How it works
Step 1: Connection Setup
Simply provide your WordPress site URL and REST API credentials. The tool connects securely to your WordPress installation and reads all your content without requiring any modifications to your site.
Step 2: Content Analysis
The migration tool analyzes your entire WordPress structure - detecting posts, pages, custom post types, translations, media, and all relationships between content. It provides a detailed preview of what will be migrated.
Step 3: Automated Conversion
The tool intelligently converts your content:
- Rich Text: WordPress HTML content is parsed and converted to Strapi's block-based editor format
- Media Files: All images, PDFs, and documents are downloaded and uploaded to Strapi with proper organization
- Translations: WPML translations are mapped to Strapi's multilingual system
- SEO Metadata: Yoast SEO data is preserved and migrated to Strapi's SEO fields
- Relationships: Categories, tags, and content relationships are maintained
Step 4: Review & Publish
Before finalizing, review the migrated content in your Strapi instance. Make any necessary adjustments, then publish everything at once.
Key Features
Zero Data Loss
Every piece of your content is carefully preserved during migration. Even complex content structures like nested blocks, custom fields, and media relationships are maintained.
Intelligent Content Parsing
WPEscape's HTML parser understands WordPress's various content formats - from traditional posts to WooCommerce products to custom post types. Each is converted to the appropriate Strapi structure.
Media Handling
Images, PDFs, and documents are automatically:
- Downloaded from your WordPress server
- Optimized for web (when applicable)
- Uploaded to your Strapi media library
- Re-linked in your content
Multilingual Support
If you use WPML for translations, we automatically detect and migrate all language versions, maintaining the language structure in Strapi.
SEO Preservation
All SEO metadata from Yoast SEO is transferred, ensuring your search engine optimization isn't lost in the migration.
Audit Trail
Every migrated item is logged with timestamps and status. You can track exactly what was migrated and when, making it easy to verify completeness.
What You Get
- Your Content: Fully migrated to Strapi with all formatting, media, and relationships intact
- Better Performance: Strapi's API-first architecture typically delivers 5-10x faster page loads
- Enhanced Security: Strapi runs on your infrastructure with no plugin vulnerabilities
- More Control: Complete control over your content structure without plugin bloat
- Future-Ready: Strapi integrates with modern frontend frameworks and headless architectures
The Migration Timeline
- Small sites (under 50 pages/posts): 1-2 hours
- Medium sites (50-500 pages/posts): 2-4 hours
- Large sites (500+ pages/posts): 4-8 hours
Most of this is automated. Your involvement is mainly in the connection setup and final review steps.
Real-World Impact
One of my recent clients migrated a 200+ page WordPress site with WPML translations and extensive media libraries. The results:
- 70% faster page loads after migration
- Eliminated 15+ plugins and their maintenance burden
- Reduced hosting costs by switching to a more efficient infrastructure
- Improved developer experience with a modern headless CMS
Get Started
The migration tool is designed for agencies, freelancers, and businesses that want to modernize their web presence without the headache of manual content migration.

Not sure whether to go with Vue/Nuxt or React/Next.js for your new frontend? I'm writing a full comparison (coming soon). If you want to go deep on either framework, I've been working through the official certifications myself:
