Nobody notices a migration that went well.
They notice the other kind. Traffic sliding in week two and nobody can say why. Forms that stopped reaching the CRM. Old URLs returning 404 to links you spent years earning.
Almost none of that is the new platform’s fault. It is what got skipped between the old site and the new one: the redirects nobody tested, the metadata nobody mapped, the pages left orphaned with nothing linking to them.
A migration is not moving content. It is moving everything the content was quietly doing.
What a CMS migration involves.
02Content and data migration
Field-mapped imports for structured content, and a person checking what scripts cannot reach.
03SEO preservation
Redirects tested on staging while the old site is still live, and metadata carried over rather than retyped.
04Integrations and tracking
Forms, CRM connections and analytics rebuilt and tested
before cutover, not after.
Who we migrate for.
Teams moving a site with years of search history, hundreds or thousands of pages, and integrations that cannot go dark on launch day.
Most migrations are judged on launch day.
We judge ours on the weeks after.

Frequently asked questions
How much does it cost to migrate a website?
It depends on page count, content types, how much can be scripted versus moved by hand, the number of redirects, and your integrations. Fixed scope and fixed price after a discovery call.
How does website migration work?
Crawl the current site, map every URL and field, build and test on staging while the old site stays live, then cut over and compare crawls.
What is a CMS migration?
Moving your content, URLs, metadata and integrations from one content management system to another, and carrying over what the old site had earned in search.
Will we lose our rankings?
Some movement in the first weeks is normal on any migration. A lasting drop usually comes from missed redirects, lost metadata or broken internal links, which is exactly what our process checks for.
How do you handle thousands of blog posts and CMS pages?
They move in batches by script or API, with URLs, categories and metadata mapped first. Volume changes the timeline, not the method.
What happens to our integrations and tracking scripts?
Rebuilt on the new platform and tested end to end before cutover, from form submit to CRM record and from page view to analytics event.
How long does a CMS migration take?
Most run [X] to [X] weeks, depending on page count and how much content can be scripted.
Can content be migrated automatically?
Most of it. Structured content moves by script or API. Rich text, embedded media and one-off layouts usually need a person, and we plan for that rather than discover it.
Which platforms do you migrate to?
Webflow and Sanity, the two platforms we build on.
What happens after the migration?
[X] days of ranking and 404 monitoring, CMS training, and a recorded walkthrough you keep. Retainer clients usually hear back within the hour, and most requests are picked up the same day.
Moving from WordPress to Webflow specifically?
We have a dedicated page for that. WordPress to Webflow migration
