Drupal 7 reached end of life in January 2025, and many enterprise roadmaps got honest fast. Moving to Drupal 10 meant a near-total rebuild anyway, so why not compare options? WordPress now runs over 40% of all websites (W3Techs), and the block editor finally feels enterprise-ready. That's how Drupal to WordPress enterprise migration went from fringe idea to board-level topic.

There's a catch, though. Bloor Research found 83% of data migration projects fail or overrun budgets and timelines. A CMS move is a data migration in disguise.

Key Evaluation Criteria for Enterprise Migration Partners

Good enterprise WordPress migration specialists rarely start with design. They start with data. A shortlist should check for:

  • database schema transformation across Drupal, Sitecore or AEM;

  • 301 redirect mapping at scale, tested before launch;

  • automated data integrity validation, not spot checks;

  • custom Gutenberg block mapping for legacy fields and shortcodes;

  • Core Web Vitals preservation, benchmarked before and after;

  • a proven zero-downtime cutover plan.

Google's research shows 53% of mobile visits are abandoned when pages take over three seconds. So performance isn't a nice extra. It's revenue.

Top Enterprise WordPress Migration Agencies

Beetweb

Beetweb focuses on custom WordPress architecture and the messy migrations others avoid: multisite platforms, legacy CMSs, years of tangled content. The team turns old content types into clean Gutenberg blocks instead of dumping raw HTML into the editor. Deployments run with zero downtime, which matters when traffic never sleeps. Think of it as a WordPress data migration agency that also builds what comes next.

Step-by-Step Enterprise Migration Methodology

Solid WordPress migration services share a similar rhythm:

  1. Audit content, integrations, URLs and SEO equity.

  2. Design the target schema and block library.

  3. Build scripted, repeatable migration jobs.

  4. Run test migrations with data integrity validation.

  5. Map and test every 301 redirect.

  6. Freeze content, migrate the delta, cut over.

  7. Monitor rankings, Core Web Vitals and errors for weeks.

Does every project need all seven steps? Not always. But skipping one is usually how a migration ends up in that 83%.
