Your CMS has to become something.

The Webflow CMS does not come with you, and what replaces it is the decision that shapes the rest of the migration. It is settled by one question: after the move, who publishes, and how often?

The question that decides it

Publishing, not preference.

Teams tend to choose a CMS on architecture and regret it on workflow. The useful question is not which system is better designed, it is what happens on a Tuesday when somebody needs a page live and the person who can do it is on holiday. Answer that first and the technical choice mostly makes itself.

This is also the single biggest reason to stay on Webflow. If visual editing by non-technical people is load-bearing for your business, every option below is a step down for them, and that cost is real even when the engineering case is strong.

Three answers

Each is correct for somebody.

Astro Content Collections

Content that lives in the repository, edited by people who are comfortable there.

What it gives you

Schemas are typed and checked at build time, so a missing field fails the build instead of shipping an empty page.
Content is versioned with the code, reviewed in pull requests and deployed with everything else.
Nothing extra to pay for, run or keep patched.

What it costs you

Editing means a Git workflow. Some marketing teams take to that and some will simply stop publishing.
No preview for a non-technical editor without building one.
Images and files become repository concerns.

A headless CMS, such as Sanity

Teams who publish often, or where the people publishing are not the people deploying.

What it gives you

Editors get a real editing interface, previews and roles, which is the closest replacement for what Webflow gave them.
Content is structured and queryable, and relationships survive the move properly.
Publishing does not require a deploy, so the marketing team is not blocked on engineering.

What it costs you

Another system to model, host, pay for and keep in step with the site.
The content model has to be designed rather than inherited. This is where most of the migration effort goes when a CMS is involved.
Two sources of truth to reason about, content and code.

No CMS

Sites whose pages change a few times a year and are edited by whoever owns the codebase.

What it gives you

Nothing to maintain, nothing to pay for, nothing to break between systems.
The fastest path to a site that just works.

What it costs you

Every content change is a code change.
It stops being right the moment somebody non-technical needs to publish, and retrofitting a CMS later is real work.

The rebuild

A Collection is not exported. It is remodeled.

Whichever answer you land on, the Webflow content model has to be reconstructed on the other side. The items can be moved once there is somewhere to move them to, and building that somewhere is the work.

Collection A schema: fields, types, and which are genuinely required.
Collection item An entry, in the repository or in the CMS.
Plain and rich text fields Typed fields, with rich text becoming a structured format rather than stored HTML.
Reference and multi-reference Real relationships the build can validate, which is usually an upgrade.
Option fields Enumerated values, checked rather than typed by hand each time.
Image and file fields Assets, moved deliberately and re-pointed. Nothing about this is automatic.
Collection template A route and the components it renders.
Item slug A route parameter, seeded from the URL that already exists.

Content migration itself is scripted rather than retyped, and verified by count and by spot check against the old site before anything is cut over.
