Move to a headless stack without losing rankings or traffic, and launch with better Core Web Vitals.
Where CMS Migrations Lose Rankings
01
Traffic & Ranking Drops
Changing URLs without a one-to-one redirect map leaves 404s, broken internal links and lost organic traffic.
02
Content & Metadata Loss
Moving from editors like WordPress to structured content often drops meta descriptions, alt text and schema markup unless each field is mapped.
03
Crawlability Issues
Client-side-only rendering can stop search engines from rendering and indexing your new pages.
04
Slow Post-Migration Performance
Replatforming without a performance focus leads to bloated JavaScript and poor Core Web Vitals, which can cost rankings and conversions.
Our Solution
As a headless CMS development company, we specialize in SEO-safe replatforming. We map every live URL before launch, migrate content with parity checks and ship a server-rendered frontend. For Caleffi that meant 5,613 pages and 24,000+ products remapped, with every URL redirected at launch.
What We Implement
Pre-Migration Mapping: keep URLs where possible, 301-redirect the rest one-to-one.
Data Transformation: legacy HTML converted to structured JSON, checked for content parity.
SSR & SSG: Full content in the initial HTML for search and AI crawlers, and a fast foundation for Core Web Vitals
AI & SEO Guardrails: Built-in sitemaps, accessibility, and AI endpoints.
No Content Freeze: Phased rollouts, so editors keep publishing during the migration.
We rebuilt xWeather's poorly-indexed SPA into a server-rendered Next.js + Storyblok platform. Using a custom pipeline, we migrated legacy content with full rich text AST transformation and asset deduplication.
Proof Point
Server-rendered HTML on every page, plus automated JSON-LD and dynamic sitemaps.
Automated migration of ~150 complex articles.
Deployed a dedicated /llms.txt file for AI crawlers that choose to read it.
We moved Caleffi’s Magento store to Shopify Hydrogen + Sanity across 4 languages and two domains (Italy and EU) without losing search visibility. Before launch we mapped every product, category, blog and FAQ URL to the new localized structure and built the redirect logic. We also kept the full analytics history, so rankings and reporting continued after the switch.
Proof Point
5,613 pages and 24,000+ products remapped. Every product, category, blog and FAQ URL was redirected at launch.
Localized URLs in 4 languages across the IT and EU domains.
Blog and FAQ moved to Sanity, plus auto-generated SEO store locator pages.
We moved MarketFinance's hardcoded Next.js site onto Contentful: 130+ landing pages and 450+ blog posts with 0 hours of content freeze. Rigid pages became reusable, SEO-friendly components, so editorial work never stopped.
Proof Point
Zero content freeze time during the entire migration.
130+ landing pages and 450+ blog posts moved into Contentful.
The marketing team continued publishing and driving leads without any technical interruption.
“FocusReactive helped us design and build a modern, high-performing website that delivers strong UX and conversion capabilities while enabling full independence for our marketing team. The new platform, built on the Storyblok CMS, is faster and more scalable, allowing us to create and manage content without relying on developers. The team delivered on time with proactive communication, weekly updates, and continuous improvements. They were highly responsive, technically strong, and great to work with, making the entire collaboration smooth and effective.”

Headless CMS Migration Platforms
Migration to Payload
Payload runs inside your Next.js app, so the CMS and the application share one TypeScript codebase. We map legacy data into typed Payload collections and check content parity before cutover.
For Xweather we moved 368 pages and stories, including ~150 complex articles, into Storyblok and cleaned up 1,500+ media assets. Editors now build and publish pages in Storyblok’s visual editor without developers.
Sanity keeps structured content next to your commerce and app data. For Caleffi we moved the blog and FAQ into Sanity alongside a Shopify Hydrogen store in 4 languages.
For SQL-heavy teams. Directus sits on your existing database and adds a REST and GraphQL API and an editor UI, so you modernize first and move content only where needed.
Built for teams that outgrew hardcoded pages. We move legacy pages into Contentful’s content model and turn them into reusable components. For MarketFinance, we moved 130+ landing pages and 450+ blog posts into Contentful with no content freeze.
Strapi is an open-source headless CMS you host yourself, so content and database stay on your infrastructure. We move legacy content into Strapi content types. Migrate to Strapi →
FAQs
SEO Migration FAQs.
Traffic is usually lost in three places: missing redirects, lost metadata and pages Google can’t render. Most SEO agencies hand a redirect spreadsheet to your developers. We are the developers, so mapping, rendering and redirects ship in the same codebase.
Before launch we crawl your legacy site, map every live URL to the new structure, check metadata parity and keep internal links intact. The new site launches on a server-rendered frontend (Next.js, or Hydrogen for Shopify stores). No unplanned 404s: live URLs get permanent redirects, and retired content correctly returns 404/410.
Our services include full technical SEO audits, URL mapping and redirect implementation, structured data (Schema) preservation, automated content transformation (HTML to JSON/Blocks), Core Web Vitals optimization, dynamic sitemap generation, and post-launch index monitoring.
Depending on the size of the project (number of pages, locales, and content types), a safe migration generally takes between 2 to 4 months. We use custom scripts and AI-assisted tools to automate the heavy lifting of data transfer, speeding up the process while reducing human error.
Yes. For Caleffi we moved a Magento store with 24,000+ products to Shopify Hydrogen + Sanity and redirected every product, category, blog and FAQ URL at launch. For WordPress sites, see the WordPress migration pages linked in the platform cards above.
Server rendering, optimized images and edge caching are part of every build, and our launches target “good” LCP, INP and CLS in real-user data.
During data migration, our custom transformation pipelines parse legacy content and map it directly into structured fields in the new CMS. From those fields the new frontend generates JSON-LD markup (Articles, Breadcrumbs, FAQs, Organizations).
Use this SEO migration checklist to prevent ranking drops when replatforming your CMS, changing URLs, or moving domains. Covers pre-launch, launch day, and post-migration monitoring.
