Migrate to Shopify Plus
A scoped migration handled by engineers who have done it before. Data integrity first, custom-app parity second, launch when it is genuinely ready.
Process
- Discovery. Catalogue audit, integration inventory, data mapping decisions. We surface migration risks in writing before any code moves.
- Build + parity. Theme rebuild on Shopify Plus, custom app re-platforming, ERP/3PL connectors, B2B setup.
- Data + UAT. Historical orders/customers/inventory move, side-by-side regression testing, soft launch on a subdomain.
- Cutover. DNS swap, monitoring window, Plus-specific tuning (Functions, Flow, Markets) and rollback rehearsal beforehand.
What you get
- A migration plan with risk register, ranked by likelihood × impact
- Engineering team that has done this on Plus, BigCommerce, SFCC, and NetSuite
- Rollback plan you can read and trust before cutover
- Post-launch support window, scoped in writing
Timeline
Scoped after discovery
Depends on catalogue size, integrations, and B2B complexity. We confirm a window in writing once the discovery surfaces the real shape of the work — committing to a day-count beforehand is how migrations slip.
FAQ
- Do you migrate from BigCommerce / SFCC / Magento?
- Yes. We work with all four. The migration patterns differ — we'll point out what changes for your platform during discovery.
- How do you handle historical orders and customer data?
- We move it via Shopify's GraphQL Admin API in batched migrations. Edge cases (refunds in flight, half-completed checkouts) get handled per case, not silently dropped.
- What's the biggest risk?
- In our experience: app sprawl. Most stores depend on 3–6 apps that are partly wired into the theme code. We map dependencies in week 1 — surprises in week 8 are how migrations slip.
- Can we keep our existing checkout customisations?
- Almost always — we re-implement Scripts as Functions and Custom Pixel logic as Plus-native equivalents. Some edge customisations need rethinking; we'll flag those.
- What about SEO during cutover?
- We map every legacy URL to its new path with redirects, retain canonical tags, and submit a fresh sitemap to GSC the day of launch.
