Replatforming to headless commerce, one slice at a time
Moving a live store to a headless architecture is not a rebuild you reveal on a launch date. It is a migration that has to keep taking orders throughout. We plan it as a sequence of small, reversible cutovers — and we start by checking that headless is actually the fix for the problem you have.
Before you migrate
Decide the problem before you decide the architecture
Headless pays for itself in three situations: several storefronts on one commerce back end, a front end that a theme cannot express, and content and commerce that live in separate systems. If your pain is slow pages or a brittle integration, a new front end can leave both unchanged, or make them worse for a while. The first week of an engagement is spent finding out which problem you have, and we will tell you if the answer is that you should stay where you are.
Scope
What a replatforming engagement covers
Fit assessment and target architecture
What the current platform does well, where it blocks you, and whether the fix is headless, a different platform, or work on the existing one. Output is a decision with reasons, not a vendor shortlist.
Catalogue, pricing, and inventory integration
The commerce back end stays the system of record. We design the API layer, caching, and invalidation so the storefront shows correct stock and price without hitting the origin for every request.
Checkout and payments
The highest-risk surface, so it moves last. Hosted or embedded checkout, payment provider behaviour, tax, shipping, and the failure modes of each — designed before the first customer reaches them.
SEO-safe migration
URL structure preserved or redirected one-to-one, structured data and metadata carried across, sitemaps and canonicals checked, and organic traffic watched slice by slice. A replatform that loses its rankings has failed whatever the performance numbers say.
Performance and rendering strategy
Static generation, incremental regeneration, or server rendering chosen per page type against how often its data changes — and budgets set for Core Web Vitals before the work starts, so they can be checked.
Handover and operations
Runbooks, monitoring on the paths that earn revenue, and a team that understands the architecture well enough to change it. A storefront only we can maintain is a worse position than the one you started in.
How we cut over without a launch day
The reason to migrate in slices is that every slice is a real test with a small blast radius. By the time the highest-traffic pages move, the approach has already survived production.
- Traffic moved behind a routing rule, one category or page type at a time, with the old storefront still serving everything else
- A mid-volume category first, so the earliest real traffic teaches the team something without putting the best-selling pages at risk
- Checkout and cart last, once catalogue and category pages have proven rendering, caching, and integration at real volume
- A rollback that is a routing change, not a redeploy — rehearsed before it is needed
