We replatform legacy and first-generation CMS platforms — WordPress, Drupal, AEM, Sitecore, Contentful, Webflow — into modern headless architecture
Headless CMS Migration Expertise
We migrate you to the CMS that fits your problem — not the one we're most comfortable selling.
At our core, FocusReactive is a technology-neutral, engineering-driven headless CMS agency. We are official partners of Sanity, Storyblok, Contentful, and Payload CMS, with extensive production experience migrating teams onto Directus and DatoCMS as well.
Headless CMS migration is not a lift-and-shift. It's a full re-architecture: content modeling, redirect strategy, integration remapping, and a Next.js frontend rebuild, sequenced so your organic traffic and editorial workflows survive the cutover intact. We've run this playbook against WordPress, Drupal, AEM, Sitecore, Squarespace, Umbraco, Webflow, Wix, Framer, and legacy Contentful setups — so the risks are known quantities, not surprises discovered mid-project.
Replatforming Done Right
As a dedicated headless CMS migration agency, we cover the full path from legacy platform to launch:
Migration Audit & Roadmap
We assess your current CMS, content models, integrations, and search footprint, then define the target architecture, URL/redirect strategy, and a phased delivery plan — before a line of migration code is written.
End-to-end, zero-downtime migration from legacy monoliths (WordPress, Drupal) or first-generation SaaS CMS to a modern headless stack with Next.js architecture — preserving your SEO rankings and redirect maps throughout.
Dedicated monthly retainers for continuous feature delivery, performance engineering, and codebase maintenance, so the platform you just migrated to doesn't quietly re-accumulate the technical debt you migrated away from.
Tested scripts, content-model blueprints, and rollback plans, refined across dozens of migrations from WordPress, Drupal, AEM, Sitecore, Contentful, and Webflow. Fewer surprises, faster timelines.
02
Unbiased Stack Selection
Before we migrate a single record, we evaluate your data models and editorial workflows against the entire headless market to choose the target platform that fits your business — not the one we're partnered with.
03
Zero-Downtime, SEO-Safe Cutover
301 redirect mapping, structured data parity, and staged rollouts protect your rankings and traffic through the switch — not just after it.
04
Tooling Without the Trap
We protect you from vendor lock-in by designing a minimal, modular architecture on the other side of the migration, where every platform has to keep earning its place in your stack.
05
Compliance Built Into the Rebuild
Migration is the moment to fix what legacy platforms let slide. We bake strict WCAG accessibility and GDPR compliance into your new frontend components natively, so you're not paying for remediation twice.
06
AI-Ready Architecture & Crawlability
By optimizing the composable infrastructure you land on, we make sure your migrated site meets the distinct, complex crawling requirements of next-generation AI agents — not just legacy search bots.
07
Brand-Safe Visual Page Builder, Day One
Your editors get freedom within guardrails defined by your design system from the moment the new CMS goes live — impossible to break the brand, easy to keep shipping pages.
Once you go headless, the CMS only handles content creation — everything else is an engineering decision. How you fetch, cache, render, and deploy that content determines whether you actually get the performance and flexibility you signed up for. That's the upside, and it's also the cost most teams underestimate going in.
FocusReactive successfully took over and enhanced our existing site and shop, making the platform faster, more stable, and significantly improving the user experience. The team delivered high-quality work on time, reduced development overhead, and proved to be proactive, knowledgeable, and highly reliable throughout the collaboration.

“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.”

Legacy-to-Headless Replatforming
As a specialized headless CMS migration agency, we take marketing teams off WordPress, Drupal, AEM, and Sitecore and onto architecture they can actually self-serve — with redirect maps, content-model parity, and Core Web Vitals optimization built into the move, not bolted on after.
Outgrown your first headless CMS? We've executed migrations at scale — thousands of pages, preserved redirect maps, maintained search rankings. We've seen the architectural patterns before, so your migration isn't the first time we're solving them.
We migrate storefronts onto composable commerce architecture — custom Next.js frontends connected to Shopify or Medusa — where products, campaigns, and editorial content relate seamlessly, without breaking checkout or catalog data in the process.
A headless CMS migration moves your content, media, templates, redirects, and key integrations onto a new platform and a new frontend architecture (typically Next.js). It lets marketing teams launch campaigns faster without legacy tooling friction, while giving your tech team a cleaner, more maintainable, API-first system to build on.
It depends on what you're migrating from and why. Sanity excels at custom content modeling and real-time collaboration. Storyblok is the strongest option when editorial independence and visual editing are the priority. Contentful fits enterprise teams managing content at scale across markets. Payload is ideal when the CMS and the application need to share a codebase. Directus works best when you're migrating on top of an existing database you want to keep. We assess your current setup and recommend the platform that fits, not the one we're most invested in.
Not if it's planned as an SEO project, not just a content move. We map every URL to a 301 redirect, rebuild structured data for parity, and validate rankings and traffic in staging before cutover. Redirect setup and post-launch monitoring are standard on every migration we run, not an optional add-on.
Most migrations run from 4-8 weeks, depending on content volume, integration complexity, and whether the frontend is rebuilt alongside the platform switch. You get a phased delivery plan upfront, so marketing has a clear timeline for new capabilities and engineering has predictable phases for redirect work, integration remapping, and QA.
Data loss, broken user journeys, and downtime are the main risks — usually caused by skipping staging validation or underestimating integration complexity. We mitigate this with tested migration scripts, rigorous staging environments, automated regression checks, and a rollback plan defined before cutover, not improvised during it.
Look for engineering-led delivery (not outstaffed juniors), production experience across multiple CMS vendors rather than a single-platform reseller, a documented redirect/SEO methodology, and a track record of migrations at your scale. We work Time & Materials with a detailed estimate upfront, keep senior engineers on the build end to end, and can show migration case studies across WordPress, Drupal, AEM, Sitecore, and legacy SaaS CMS platforms.

The choice of CMS shapes every downstream decision — your migration complexity, your content model, your editor training, and your ongoing costs. Here's how the major platforms compare specifically from a migration lens:
The headless CMS market has matured enough that "which one should I use?" now has real, defensible answers — not just "it depends." Here's how the leading platforms stack up, and who should default to what.
