What Is a Legacy CMS Migration to Next.js?

A legacy CMS migration means replacing platforms like Sitecore, TYPO3, Drupal, Joomla, Kentico, or Adobe Experience Manager with a Next.js frontend backed by a headless CMS. Your content, URLs, metadata, and integrations stay intact — what changes is the rendering layer, which moves to React-based static and server-side generation. The result is a site that's faster, more secure, and one your developers actually want to work on.

Wo Projekte scheitern

Sitecore, AEM, and Kentico licensing alone can run six figures a year That's money going to a vendor, not to building anything.
Legacy monolithic renderers routinely push page load times past 4 seconds Core Web Vitals tank, and organic traffic follows — quarter after quarter.
When your CMS version hits end-of-life, security patches stop coming A single unpatched vulnerability can expose customer data and land you in a compliance nightmare.
Try hiring a TYPO3 or Kentico specialist right now It's a small talent pool, and it's shrinking. Maintenance drags, features take forever, and when someone quits, they take years of institutional knowledge with them.
Every content change becomes an engineering task — a deploy cycle, a cache purge, a ticket in a queue Marketing teams can't move fast when they're waiting on developers to publish a banner.
And while you're stuck in that monolith, competitors are already shipping personalization, A/B testing, and composable features Modern APIs and microservices are off the table when your architecture can't accommodate them.

Compliance

Full URL & Redirect Mapping

Every existing URL gets audited, mapped, and covered with 301 redirects. No orphaned pages, no broken backlinks, no traffic falling into a void.

Content Schema Migration

We pull content models out of your legacy CMS and restructure them into a clean headless schema. Relationships, taxonomies, and metadata all come with them.

SEO Equity Preservation

Meta tags, structured data, canonical URLs, sitemaps, internal linking — all rebuilt to match what you had, validated with crawl diffs before and after launch.

Security Hardening

Ditching a server-side CMS shrinks your attack surface considerably. Static pages served from an edge CDN eliminate entire categories of vulnerabilities. API routes get authentication and rate limiting from day one.

Performance Optimization

ISR, static generation, and edge caching get you to sub-second load times. Images run through next/image automatically — modern formats, right sizing, no manual work.

Access Control & Auth

Your existing auth flows and role-based access controls move to modern identity providers. SSO, SAML, OAuth2 — all supported.

Was wir bauen

Automated Content Extraction

Custom scripts handle the content extraction. Assets, metadata, database records — none of it requires manual copy-paste.

Headless CMS Integration

We connect Sanity, Contentful, Storyblok, or whatever headless CMS fits your team, with type-safe content models throughout.

Incremental Static Regeneration

Editors can publish instantly without triggering a full redeploy. ISR rebuilds pages on demand — static-site speed, without the static-site publishing headaches.

Component Library Buildout

Every legacy template gets rebuilt as a reusable React component, documented in Storybook, with design system tokens baked in.

Third-Party Integration Rewiring

Analytics, CRMs, marketing automation, e-commerce — everything reconnects through modern API layers. Nothing gets quietly dropped.

Parallel Running & Validation

We run both sites in parallel before cutover, comparing rendered output, SEO signals, and functionality side by side. You don't go live until parity is confirmed.

Unser Prozess

01

Platform Audit & URL Inventory

We crawl your existing site and document every URL, content type, integration, and custom module. You get a migration scope document with a real risk assessment before we write a line of code.
Week 1–2
02

Architecture & CMS Selection

Then we design the Next.js architecture, pick the headless CMS, define the content schemas, and map out the redirect strategy. Every technical decision is documented and signed off before anything gets built.
Week 2–3
03

Content Migration & Frontend Build

Content extraction runs via automated scripts while the engineering team builds the component library, page templates, and API integrations in parallel — no waiting on sequential handoffs.
Week 3–8
04

QA, SEO Validation & Parallel Run

Before cutover, we run visual regression tests, crawl comparisons, Lighthouse audits, and stakeholder UAT. Both sites run simultaneously so you can see the parity yourself.
Week 8–10
05

Launch & Decommission

Then DNS cuts over to the Vercel edge network, the legacy CMS gets decommissioned, and we spend 30 days on post-launch monitoring, redirect validation, and performance tuning.

Häufige Fragen

Verliere ich SEO-Rankings bei der Migration von Sitecore oder Drupal zu Next.js?

Nein, wenn die Migration richtig durchgeführt wird. Wir erstellen ein vollständiges URL-Inventar, führen 1:1-Redirect-Mapping durch, bewahren alle Meta-Tags und strukturierten Daten und vergleichen die Crawl-Ergebnisse vor und nach dem Launch. Die meisten Kunden sehen tatsächlich Ranking-Verbesserungen innerhalb von 8 Wochen — schnellere Core Web Vitals Scores haben einen echten, messbaren Effekt auf die organische Performance.

Wie lange dauert eine Legacy CMS Migration zu Next.js?

Typische Migrationen dauern 8–12 Wochen für Websites mit weniger als 2.000 Seiten. Größere Enterprise-Sites mit komplexen Integrationen, mehrsprachigen Inhalten oder stark angepassten Modulen können 12–20 Wochen dauern. Wir bewerten jedes Projekt einzeln und legen eine feste Timeline beim Kickoff fest — keine beweglichen Ziele.

Was passiert mit dem Workflow meiner Content-Redakteure nach der Migration?

Redakteure erhalten ein modernes Headless-CMS — Sanity oder Contentful sind häufige Optionen — mit Live-Preview, visuellem Editor und strukturierten Content-Modellen. Ehrlich gesagt finden die meisten Teams es schneller als das, was sie hatten. Wir führen Trainings-Sessions durch und erstellen Dokumentation, die speziell für Ihr Content-Team geschrieben ist, nicht generische How-To-Guides.

Kann ich von TYPO3 oder Kentico migrieren, wenn sie Custom Extensions verwenden?

Ja. Jede Custom Extension, jedes Plugin und Modul wird während der Discovery-Phase überprüft. Funktionalität wird als Next.js API Routes, Serverless Functions oder SaaS-Integrationen von Drittanbietern neu aufgebaut — je nachdem, was passt. Alles wird dokumentiert, einschließlich was es ersetzt und warum.

Wie viel spare ich bei Hosting nach der Migration weg von AEM oder Sitecore?

Die meisten Enterprise-Kunden reduzieren Hosting- und Infrastrukturkosten um 50–80%. Sitecore und AEM benötigen dedizierte Server, Java-Runtimes und teure Lizenzen zusätzlich dazu. Next.js auf Vercel läuft auf Edge-Infrastruktur mit nutzungsbasierter Preisgestaltung — normalerweise $500–2.000/Monat, im Vergleich zu den fünf- oder sechsstelligen Rechnungen, die Legacy-Hosting normalerweise generiert.

Handhabt ihr mehrsprachige und Multi-Region Site Migrationen?

Ja. Wir migrieren i18n-Konfigurationen, hreflang-Tags, locale-spezifische Inhalte und regionale URL-Strukturen. Next.js hat internationales Routing eingebaut — wir konfigurieren es, um dein bestehendes mehrsprachiges Setup zu entsprechen oder zu verbessern, einschließlich Locale-Erkennung und Fallback-Handling.
