SAP Composable Storefront Migration for Teams Already on Commerce Cloud

Already on SAP Commerce Cloud? Move from Accelerator to Composable Storefront without a rebuild. Book your architecture assessment.

From SAP Accelerator to a Headless Composable Storefront

Most teams that migrate to SAP Commerce Cloud solve the infrastructure question and then stop, leaving the Accelerator storefront layer untouched. Unfortunately, SAP is no longer investing in the Accelerator, creating a gap between "still works" and "actually ready for what’s next" that grows quietly until a new market launch, a backlog review, or a backend change.

Novarto’s Composable Storefront Migration service closes this gap. We assess the real complexity of your current storefront, recommend a suitable migration path, and help you move to SAP Composable Storefront (Spartacus), SAPs headless storefront, without compromising your existing SEO or UX.

The advantages at a glance:

Complexity and effort assessment: We take an inventory of your current storefront, conduct a gap analysis against SAP’s OCC APIs, and provide an accurate scope before you commit to anything.
SEO and performance consistency: We implement Node.js server-side rendering to ensure that your migration preserves your existing organic visibility and performance, rather than simply introducing new architecture.
AI-ready architecture: Composable Storefront is where SAP’s future API-only capabilities will first be available.
Custom component migration: For customisations without a native Composable Storefront equivalent, we first explore existing solutions before opting for a full rebuild.

Ways to Get There: Choose the path that fits your situation.

Decision 1: Your end state - Brownfield or Greenfield

Brownfield / like-for-like

This is ideal for teams that want to move onto SAP’s recommended architecture without changing the UX that their customers are already familiar with. We migrate the underlying architecture from Accelerator to Composable Storefront, keeping your current look and feel intact.

Perfect for:

The lowest-disruption path back onto SAP’s API-first roadmap
Teams whose current storefront UX still works for their customers
The fastest route to a supported, future-ready architecture

Greenfield / full reimplementation

This is ideal for teams whose storefront UX has outgrown the capabilities of Accelerator’s templates. This involves a full redesign, built fresh on SAP Composable Storefront.

Perfect for:

Teams that are consolidating multiple legacy customisations into one clean build
Storefronts that are overdue for a UX overhaul
Organisations that want the migration to double as a UX investment

Decision 2: Your approach - Gradual or Big Bang

Gradual, with coexistence.

For this one, the old and new architectures run side by side while specific pages or flows migrate incrementally. It’s a transition state on the way to your chosen end state, not a destination of its own.

Perfect for:

Phased migrations that de-risk the move
Teams validating the architecture before a full commitment
High-traffic flows (checkout, PDP) that benefit most from moving first

Big bang

The new system is built in full, then cut over to at a single point in time.

Perfect for:

Teams that want a fixed, finished state without a prolonged dual-architecture period
Situations where running two architectures in parallel isn’t operationally practical

Either end state — brownfield or greenfield — can be reached through either approach. Not sure which combination fits your setup? Tell us where your storefront actually stands and we’ll tell you honestly what the effort looks like.

What Novarto migration service package brings

Assessment: We assess complexity, ROI, and support requirements before recommending a course of action.
Deep Spartacus expertise: Our engineers work daily with SAP’s own open-source Composable Storefront framework rather than a generic headless stack.
European quality standards: We are fully compliant and secure with ISO 27001, 9001, and 20000-1 certifications.
Prototyped before built: UX changes are approved by stakeholders in Figma/FigJam before a line of production code is written.

FAQ Section

Q1: Is SAP Composable Storefront a headless storefront?

Yes. SAP Composable Storefront (formerly Spartacus) is SAP’s headless storefront for SAP Commerce Cloud. The front end runs as a separate application and talks to the commerce backend through APIs, so you can change the customer experience without touching the core.

Q2: What’s the actual difference between Accelerator and SAP Composable Storefront?

Accelerator is SAP’s legacy JSP-based storefront template. Composable Storefront (built on Spartacus, SAP’s open-source Angular framework) is SAP’s current API-first architecture for modular, headless commerce.

Q3: How do we know if we’re ready for this, or if we should wait?

It comes down to three things: how much custom logic is wired into your current Accelerator layer, whether the investment is justified by what it improves (personalization, marketing performance), and how often you’re already leaning on vendor support versus what you’re missing from new feature releases. Our assessment answers this directly rather than assuming composable is automatically the right call.

Q4: Does the Accelerator deprecation affect us if we’re already on Commerce Cloud?

Yes, in the sense that it’s worth an honest decision, but not as a forced deadline. Accelerator is deprecated, meaning it’s no longer where SAP is adding new capability, though it stays functional in the meantime. The real question isn’t "when do we have to move," it’s "when does staying put start costing us more than moving would."

Q5: Will migrating improve storefront performance?

It can. Composable Storefront uses server-side rendering, which keeps pages fast and visible to search engines.
