Why CMS migrations break

Pages transfer. Structure doesn’t. Rich content blocks collapse into plain HTML. Image references break when media libraries change paths. SEO metadata vanishes, internal links point nowhere, and custom post types lose their fields. Standard export tools move text, but not the architecture that makes your content work. We map your full content model, preserve every relationship, and redirect every URL.

Content structure preserved

Custom post types, taxonomies, content blocks, and field groups. Transformed to match your new CMS’s content model.

SEO continuity

URL redirects generated automatically. Meta titles, descriptions, and canonical tags mapped to the new platform.

Media library migrated

Images, documents, and videos transferred with correct references. No broken thumbnails or orphaned files.

Any platform, any direction

WordPress, Drupal, Shopify, Contentful, Strapi, Webflow, Ghost, Sanity, static site generators.

What most teams try first

WordPress export/import XML

The appeal

Built into every WordPress install. Export to XML, import into the new system.

Where it breaks

Works for basic posts and pages. Custom fields, page builders (Elementor, Gutenberg blocks), and ACF data get dropped or mangled.

Copy-paste by editors

The appeal

Manual but reliable. Each editor migrates their own content section.

Where it breaks

Scales badly. A 500-page site means weeks of manual work, inconsistent formatting, and missed metadata. And someone still needs to handle redirects.

Self-serve migration plugin

The appeal

Automated, platform-specific, often free or cheap.

Where it breaks

Template-based field mapping. Handles standard content types, drops everything custom. No validation pass, no redirect generation.

Built for these situations

Organizations switching CMS platforms with hundreds of pages, custom content types, and SEO equity worth protecting
Teams moving from a monolithic CMS to a headless architecture
Companies that ran a standard import and discovered half their content arrived without formatting, images, or metadata
Marketing teams who can’t afford to lose organic search rankings during the switch
