We move your website from WordPress, Sitecore, Drupal, or any legacy CMS to Strapi or Payload CMS, so it’s ready for any AI client and visible in AI search.

Still Deciding? Here’s What You Leave Behind With Your Legacy CMS

It was the right choice once. Then your business grew and the platform didn’t. Whether it’s WordPress, Sitecore, or Drupal, we see the same four problems in almost every website we audit, and the move to headless fixes all four.

Before · Legacy CMS

AI-readiness gaps
Your content is locked inside page templates.
Performance bottlenecks
Every new feature makes your website slower.
Technical debt
Years of quick fixes nobody dares to touch.
Vendor lock-in
License fees, plugins, and partners you can’t walk away from.

After · Headless CMS

AI-ready content
Structured, API-first content any AI tool can work with.
Fast by design
Google rewards fast Core Web Vitals, and AI crawlers read fast pages first.
Clean architecture
Clean code your team understands and grows.
Open source, yours to keep
No license fees. Your code, your data, your choice of partner.

How We Migrate, Phase by Phase

Five phases, the same ones our delivery team runs on every project. You see a working website early, and you can launch one brand, market, or section at a time instead of everything at once.

01
About 1 week

Kickoff

We agree on goals, scope, and who signs off, and get access to your current website. You also decide here whether to launch all at once or in parts, because that shapes every release after it.

02
3–5 weeks

Discovery and Scoping

We audit your content, templates, integrations, and SEO, design the content model and architecture, and turn it all into a backlog and a roadmap.

03
1.5–2.5 weeks

Setup (Sprint Zero)

Strapi or Payload, a Next.js frontend from our starter, dev and staging environments, and automatic deploys. The team starts the first sprint with no blockers.

04
Depends on scope

Build and Migrate

Four tracks run side by side in sprints, with a demo after each one:

  • Content model, roles, and locales
  • A fast Next.js frontend, rebuilt or redesigned
  • CRM, ERP, analytics, search, and forms
  • Scripted content migration, checked against the source
05
7 days before to 3 after

Launch

Content freeze, final QA, 301 redirects, a go/no-go meeting, and the switch. We watch the first 72 hours and sign off with you.

Summary
01–05

Kickoff to Launch

Discovery and setup take 4.5–7.5 weeks. The build depends on your scope. Running several brands or markets? We launch them one at a time.

Get Cited by AI. Rank Higher on Google.

Your buyers don’t only google anymore. They ask ChatGPT, Perplexity, and Google’s AI Overviews. Most website migration services still treat SEO as a checklist item at the end. We plan for both search and AI answers from day one, so your new website is built to rank and built to be cited. Lokalise’s mobile LCP dropped from 3.4 s to 2.2 s, and Meilisearch’s PageSpeed score went from 65 to 98.

Every URL mapped

A full redirect map, tested before launch.

Metadata carried over

Titles, descriptions, canonicals, and hreflang.

Faster Core Web Vitals

A lighter frontend Google rewards.

Built for AI answers

Schema, llms.txt, and content AI tools can quote.

Why We’re Faster: Scripts, Not Copy-Paste

We don’t move content by hand. Our own migration tooling moves it by script, so every run is repeatable and checked against the source.

Notum Migration Tooling

Scripted importers for WordPress, Sitecore, Ghost, and other CMSs, plus content mapping and validation reports, so we can rerun the whole migration until launch day.

A Direct Line to Strapi and Payload

We’re a Strapi Enterprise Partner and a Payload CMS Featured Partner, with shared Slack channels to both core teams. When something blocks your migration, we take it straight to the people who build the CMS.

Your Project. Your Call.

You lead the migration, and nothing moves without your sign-off. Your team learns the new platform while we build it, so they’re ready to run it on day one. We deliver a faster website and the numbers to show for it.

1.

You Approve Every Step

Nothing moves forward without your sign-off, so you stay in control from first scope to launch.

2.

Wins to Share Along the Way

Regular demos, access to the project board, and milestone summaries ready for your leadership and team.

3.

Results You Can Present

At launch, you get a results report with before-and-after metrics, ready for your leadership.

4.

A Team That Grows With It

We train your marketers, editors, and developers to get the most out of the platform and grow with it.

What We Check Before, During, and After Launch

A migration rarely fails on the big things. It fails on a forgotten redirect, a form nobody tested, or a tracking tag that didn’t make the move. That’s why we run the same checklist on every project.

Content

Inventory, content model, and what to archive.

SEO

URL map, redirects, metadata, and schema.

Integrations

Forms, CRM, analytics, and consent.

Go-live

Cutover plan, fallback, and monitoring.

Headless CMS Migration FAQ

How long does a headless CMS migration take?

Discovery and setup take 4.5–7.5 weeks. The build depends on your scope: the number of templates, languages, and integrations. Running several brands or markets? We launch them one at a time, as the website migration project plan shows. You get a precise timeline after discovery.

How much does a CMS migration cost?

It depends on the number of websites, languages, templates, and integrations. Add what you need to the cart above and you get a time and cost estimate, no call needed.

Will our website go down during the migration?

No. Your current website stays live while we build the new one. On launch day, we switch traffic over and keep the old system ready as a fallback.

What happens to our SEO and AI visibility?

We map every URL, set up 301 redirects, carry over metadata, and monitor rankings after launch. Structured content and schema make your website easier for AI tools like ChatGPT and Perplexity to cite, and a faster website usually helps your Core Web Vitals, too.

Strapi or Payload: which one is right for us?

Both are open-source, TypeScript-native, and built for enterprise. We’re partners of both, so we recommend the one that fits your team and use case after the audit.

Can you migrate from a CMS that’s not listed here?

Most likely, yes. If your CMS can export content or has an API, we can script the migration. Tell us what you run and we’ll confirm.
