What Is Content Migration for Publishing Sites?

Moving a large publishing site to a new platform means shifting thousands—sometimes tens of thousands—of articles, media assets, taxonomies, and metadata without losing URL structures, internal links, SEO authority, or editorial workflows. It requires custom tooling, precise redirect mapping, and thorough post-launch validation. Get it wrong, and you lose traffic that took years to build.

Wo Projekte scheitern

Organic search rankings built over years can collapse after a platform switch Traffic drops of 40-70% are common, and recovery—if it happens at all—takes 6-12 months.
Broken internal links across thousands of interconnected articles create cascading crawl errors that destroy link equity and wreck the reading experience. Crawl errors cascade, destroying link equity distribution and user experience
Taxonomy and category structures rarely map cleanly to a new CMS Content becomes disorganized, archives break, and readers can't find their way around your site.
Media assets—images, videos, embeds—get orphaned or stripped of alt text Image search traffic disappears and accessibility compliance fails.
Custom shortcodes, widgets, and embedded content break on export Articles render incorrectly, and reader trust erodes fast.
No rollback plan when something breaks mid-migration leaves you stuck between a broken new site and an outdated old one with no clean way forward. You're stuck between a broken new site and an outdated old one with no clean path forward

Compliance

Automated URL Mapping

We build custom scripts that crawl your existing site and generate a complete URL map with 1:1 redirect rules. No manual spreadsheets, no missed pages.

SEO Signal Preservation

Every meta title, description, canonical tag, structured data block, and Open Graph tag migrates intact. We validate each page against source data before launch.

Content Model Translation

We restructure content from monolithic HTML blobs into clean, structured data models in your target CMS. Categories, tags, authors, and relationships all transfer correctly.

Media Asset Pipeline

Images, videos, and downloadable files migrate with preserved filenames, alt text, and optimized formats. We re-encode where needed for performance gains.

Redirect Chain Auditing

We detect and flatten existing redirect chains before adding new ones. Your site launches with clean, single-hop 301 redirects across every legacy URL.

Post-Launch Monitoring

We monitor Google Search Console, crawl errors, and traffic patterns for 30 days after launch. Ranking anomalies get flagged and fixed immediately.

Was wir bauen

Bulk Content Export & Transform

Custom ETL pipelines extract content from any CMS—WordPress, Drupal, Ghost, custom databases—and transform it into your target schema.

Shortcode & Embed Conversion

We parse and convert platform-specific shortcodes, oEmbed blocks, and custom widgets into portable, standards-based components.

Author & Contributor Mapping

Author profiles, bios, social links, and byline attribution carry over with correct relationships to every article.

Internal Link Rewriting

Every internal link in your content body gets rewritten to the new URL structure. No stale references left behind.

Staging Environment Validation

Full migration runs on staging first, with automated diff reports comparing source and destination content page by page.

Editorial Workflow Setup

We configure your new CMS with publishing workflows, preview environments, and role-based permissions built around how your editorial team actually works.

Unser Prozess

01

Content Audit & Mapping

We crawl your entire site and catalog every content type, taxonomy, media asset, and URL pattern. You get a migration map with clear source-to-destination rules.
Week 1-2
02

Pipeline Development

We build custom migration scripts and transformation pipelines specific to your source and target platforms, then run initial test batches against a subset of content.
Week 3-4
03

Staging Migration & QA

The full migration runs on staging. Automated tests verify URL accuracy, content integrity, media assets, and redirect coverage. Your team reviews and signs off before anything goes live.
Week 5-6
04

Production Cutover

We run the production migration during a low-traffic window, activate redirects, submit updated sitemaps, and verify everything in real time.
Week 7

Häufige Fragen

How long does a large content migration take?

Most migrations of 5,000-50,000 pages take 6-10 weeks from audit to production cutover. The timeline depends on content complexity, the number of custom content types, and how many legacy systems are involved. Sites with clean, well-structured data move faster than those carrying years of accumulated technical debt.

Will I lose SEO rankings during migration?

With proper 301 redirect mapping, canonical tag preservation, and structured data migration, ranking loss is minimal—typically under 2% of organic traffic. Full URL coverage and immediate sitemap resubmission are what make the difference. We monitor Search Console daily for 30 days post-launch to catch and fix anything that comes up.

Can you migrate from a custom or proprietary CMS?

Yes. We've migrated content from custom PHP systems, legacy .NET platforms, and proprietary publishing tools. If the content lives in a database or is accessible via API or export, we can extract and transform it. We write custom parsers for non-standard formats and validate output against source data.

What happens to my images and media files?

Every image, video, PDF, and downloadable file migrates with preserved filenames, directory structure, and metadata including alt text and captions. We optimize images during transfer—converting to WebP or AVIF where appropriate—and verify that every media reference in your content resolves correctly.

Do you handle redirects for changed URL structures?

Absolutely. We generate a complete redirect map covering every URL on your current site. Existing redirect chains get flattened, edge cases like trailing slashes and query parameters get handled, and redirects are implemented at the edge for near-zero latency. Everything gets tested before and after launch.

What if we need to keep publishing content during migration?

We build delta migration scripts that capture content published between the initial export and final cutover. Your editorial team keeps working normally throughout. On cutover day, we run a final delta sync to pick up any new or updated content—nothing published during the migration window gets lost.
