Oracle Commerce to Shopify Plus migration
We migrate Oracle Commerce (formerly ATG) and Oracle Commerce Cloud stores to Shopify Plus from Melbourne, LA, and London. Oracle Commerce is deep, capable, and enterprise-ready. It's also expensive to maintain, slow to ship, and sourced from a shrinking specialist pool. Oracle's own strategic focus has moved to Oracle CX Commerce and Oracle Retail, leaving traditional ATG as a legacy product in all but name.
We handle the full enterprise move: ATG droplets, page slots, Oracle Commerce Cloud configurations, Endeca search indices, customer segments, price lists, and enterprise B2B configurations. Oracle backend integrations (Oracle ERP Cloud, NetSuite, Oracle CX) rewire rather than rebuild.

Every ATG droplet, every Commerce Reference Store extension, every page slot, every Endeca dimension and property. We document what's native in Shopify Plus, what's a Shopify app or Function, and what needs to be rebuilt. Oracle Commerce Cloud installs get a separate review of Cloud-specific infrastructure and the Oracle managed services layer.
ATG's repository architecture, SKU hierarchy, and pricing structures map to Shopify differently than they did in Oracle. We build the translation layer for product catalogs, price lists, customer profiles, and promotional logic. ATG Commerce's B2B features map to Shopify B2B company profiles and price lists. Complex pricing logic rebuilds using Shopify B2B or Shopify Functions.
Endeca is ATG-specific and doesn't transfer. Shopify's native search handles basic needs, but most Oracle migrations move to Algolia, Nosto, Klevu, or Tagalys for parity with Endeca's faceting, refinement, and merchandising capabilities. We migrate the search index, rebuild the facet and refinement logic, and preserve merchandising rules during the move.
Oracle Commerce URL structures and site-specific routing need specific redirect logic. Multi-site configurations with hreflang tags map market by market. We build the 301 map, test through a crawler pre-launch, migrate canonicals and structured data, and monitor Search Console through the first four weeks post-launch.
Oracle ERP Cloud, NetSuite, Oracle CX, PIM, OMS, WMS, tax, marketing automation. Often iPaaS-managed - we rewire connections, not replace middleware. Parallel environments, stakeholder UAT, staged cutover by market, on-call coverage through week two. Enterprise data volumes get dedicated sync windows.
- Ship before enterprise data reconciles fully. Product, customer, and order counts match 1:1 or we don't launch.
- Rip out your Oracle backend. The storefront is leaving, not the ERP or CX suite. Integrations rewire, they don't restart.
- Sign off on a multi-site redirect map we haven't crawler-tested. Every redirect is verified pre-launch.
- Promise Endeca parity on Shopify's native search. Honest search replacement is part of scoping, not an afterthought.
For Oracle Commerce buyers, headless often makes sense from day one. Your team already operates with frontend and backend separated through the ATG pattern. Hydrogen gives you the same split with less overhead than a full custom SPA.
That said, classic Shopify Plus covers more enterprise B2B use cases than most Oracle teams assume. Checkout Extensibility, Shopify Functions, and Shopify B2B handle most of the feature gaps. We scope both paths during discovery.
Phased path also works: classic now to reduce migration risk, headless once the business is stable on the new platform.
Frequently Asked Questions about
Oracle Commerce to Shopify Plus Migration
If you have more questions, we're happy to answer them - just reach out.
How long does an Oracle Commerce to Shopify Plus migration take?
16 to 24 weeks for most Oracle Commerce installs. Complex ATG customisations, deep Endeca configurations, multi-site or multi-region setups, or heavy Oracle backend integration sit at the longer end. Oracle Commerce Cloud migrations are similar in timeline to on-prem ATG.
What replaces Oracle Endeca search?
Endeca is ATG-specific and doesn't transfer. Shopify's native search covers basic needs. For Endeca parity (faceting depth, merchandising rules, business-user control), most enterprise migrations move to Algolia, Nosto, Klevu, or Tagalys. We scope the right replacement during discovery based on your catalog size and merchandising workflow.
What happens to ATG droplets and custom business logic?
Each droplet is audited into one of three paths: features Shopify Plus does natively (retired), features covered by a Shopify app or Shopify Functions (replaced), or bespoke logic rebuilt as a Shopify app, theme section, or Hydrogen component (rebuilt). Most ATG droplet libraries shrink 60 to 80 percent in the move.
Will our Oracle ERP integration still work?
Yes. Shopify integrates cleanly with Oracle ERP Cloud, NetSuite, and other Oracle backend systems via middleware (Mulesoft, Boomi, Patchworks, Celigo) or direct API. You're leaving the storefront, not the ERP. Most Oracle integrations reconfigure rather than replace during the migration.
Can we migrate ATG Commerce events and personalization?
ATG's event system and scenario-based personalization don't transfer directly. We map each personalization use case and rebuild it using Shopify Audiences, Shopify Functions, or a dedicated personalization tool (Nosto, Dynamic Yield) depending on complexity. We audit every scenario during discovery and confirm parity before committing to scope.
Is Oracle actually deprecating ATG?
Not officially, but strategic attention has clearly moved to Oracle CX Commerce for cloud-first customers and Oracle Retail for enterprise retailers. For brands with active commerce roadmaps, ATG is increasingly a platform you maintain, not a platform Oracle invests in.
What if we're on Oracle Commerce Cloud rather than on-prem ATG?
Oracle Commerce Cloud migrations are slightly different in infrastructure but similar in scope. Cloud installs usually have fewer server-level customisations but more Oracle-specific managed services tooling that needs replacement mapping during scoping.
