Sitecore → Astro on Sanity
Escape Sitecore licensing and complexity — re-platform to a fast, headless Astro + Sanity stack.
Sitecore is powerful and expensive — in licence fees, hosting and the specialists to run it. We migrate the content and capability you actually use onto a lean, headless Astro + Sanity stack on Cloudflare: faster, far cheaper to run, and easy to edit.
Sentry's Sitecore migration moves the content and capability you actually use onto a lean headless stack — Astro and Sanity on Cloudflare — preserving the content model and editorial workflow while removing the enterprise licence, hosting and specialist costs.

Sentry.ioKPIs we move — measured, owned, reported
Every KPI is tied to a named owner and a target agreed up front — so this service is accountable to outcomes, not activity, for every stakeholder who consumes the value.
Capability Maturity — we walk you up the five levels
Operated at Level 4 · Quantitatively Managed — measured, predictable and owned. We track this rank and raise it over time. See the five levels →
Why this matters
Functional value, value-stream value — and why it can't be ignored.
Migrates Sitecore content and capability onto a headless Astro + Sanity stack on Cloudflare — preserving structure and editorial workflow while removing licence and infrastructure weight.
Frees the value stream from heavy licensing and specialist dependency: the same or better digital experience at a fraction of the run-cost, faster to ship and change.
Sitecore's licence, hosting and specialist costs compound every year — for capability most teams barely use. Staying put means paying enterprise prices for the speed and agility a headless stack delivers for less.
One data layer · measured & owned
Every service creates data — captured, measured, owned.
Sitecore → Astro on Sanity doesn’t just run — it generates signal. We land that data in one warehouse and turn it into live KPIs tied to a named owner, so performance is attributable and acted on, never trapped inside a single tool.

How we select technology
We choose technology last — for the outcomes it has to earn.
Never tech for its own sake. A tool joins the stack only where it measurably protects value, cuts cost or unlocks speed — fit to a designed system, owned where it counts, and measurable from day one. How we select technology →
Speed
Modern, edge-served stacks are sub-second. Slow surfaces cost conversion and SEO every single day.
Cost
Cut licence, hosting and per-task SaaS fees — pay for capability, not lock-in or idle enterprise tiers.
Security
Flat, edge architecture with almost nothing left to attack — fewer moving parts, smaller surface.
Ownership & no lock-in
Composable and self-hosted where it counts — you own the system, not rent someone else’s.
Measurability
Clean data and KPIs baked in — you cannot improve, automate or apply AI to what you cannot measure.
Fit to process
The right tool for a designed system — selected against process readiness, so it amplifies, not adds friction.

FAQ
Common questions
Why migrate off Sitecore?
Because its licence, hosting and specialist costs compound every year, for capability most teams barely use. Staying put means paying enterprise prices for the speed and agility a headless stack delivers for considerably less. The question is not whether Sitecore is capable; it is whether you are using what you are paying for.
Will we lose the enterprise capability we rely on?
The capability you actually use is migrated; the capability you pay for and do not use is what gets dropped. Establishing which is which is the first job, because the expensive mistake is discovering a dependency after the licence has been cancelled rather than before.
What replaces Sitecore for our editors?
Sanity, giving editors a clean, modern authoring experience, with the content model and editorial workflow preserved rather than reinvented. A migration that forces a content team to relearn how they work fails on adoption even when it succeeds technically.
How risky is a Sitecore migration?
It is run as a controlled cutover rather than a rebuild. Content, structure, redirects and SEO are carried across with care, and the move is staged with rollback available. The alternative — a big-bang switch on an enterprise platform — is where these projects usually go wrong.
What actually gets cheaper?
The licence, the hosting and the specialist skills needed to run the platform. The site itself runs sub-second and edge-served on Cloudflare, which costs a fraction of enterprise hosting. Those savings are modelled in the Financial Value Model before the work is committed to.
How do we decide whether it is worth doing?
With a free Discovery session and a Financial Value Model. Discovery produces fourteen structured commercial outputs, including what Sitecore currently costs to keep and what the migration would return. If the numbers do not support moving, that is a legitimate outcome.
Start here · the free first step
Sitecore → Astro on Sanity starts the same way every engagement does: with Discovery.
Two distinct moves — a free, no-obligation Discovery Session to find your value at stake, then the Discovery & Blueprint: 14 structured outputs — value model, roadmap and business case — before a pound of delivery is committed.
