CMS Migration

Introduction

A CMS migration is one of the most critical moments in website development. It offers the opportunity to modernize the technical foundation while also carrying significant SEO risks. A professionally executed migration can improve search engine rankings, while a poorly planned migration can lead to massive ranking losses.

What is a CMS Migration?

A CMS migration refers to switching from one Content Management System to another. This can have various reasons:

• Technical Modernization: Switch to a more modern, secure system
• Functional Extension: Better content management features
• Performance Improvement: Faster loading times and better user experience
• Cost Optimization: Switch to more cost-effective solutions
• SEO Improvement: Technical SEO optimizations through modern CMS

Common CMS Migrations

WordPress to Headless CMS

The switch from WordPress to a headless CMS like Strapi, Contentful or Sanity is becoming increasingly popular. Advantages:

• Better Performance: Faster loading times through static generation
• Flexibility: Frontend and backend can be developed independently
• Scalability: Better performance with high traffic

Drupal to WordPress

Migration from Drupal to WordPress is common for smaller to medium-sized websites:

• Easier Operation: WordPress is more user-friendly
• Larger Community: More plugins and themes available
• Cost Efficiency: Lower development costs

Legacy Systems to Modern CMS

Migration from old, self-developed systems to modern CMS:

• Security: Modern security standards
• Maintainability: Easier updates and maintenance
• SEO Features: Integrated SEO tools

SEO Risks in CMS Migrations

Critical SEO Factors

Common Mistakes

1. No URL mapping strategy: URLs are not redirected correctly
2. Loss of meta data: Title tags and meta descriptions are not transferred
3. Missing 301 redirects: Old URLs show 404 errors
4. Broken internal links: Internal linking no longer works
5. Loss of structured data: Schema.org markup is missing

Preparing the CMS Migration

1. SEO Audit of Current System
