Phased Migration: Commerce Optimizer as Your Bridge to ACCS

Not every enterprise can afford a 12-month big-bang migration to Adobe Commerce as a Cloud Service. Adobe's recommended phased path uses Commerce Optimizer as a bridge — delivering ROI while backend complexity is untangled.

Phase 1 — Connector + discovery: Deploy Optimizer Connector from existing PaaS/on-prem Commerce. Enable Live Search and Recommendations on a pilot category or region. Measure search exit rate, conversion, and revenue per visit.

Phase 2 — Edge Delivery storefront: Launch Commerce Storefront on Edge Delivery for a brand or market while checkout remains on existing Commerce. Prove Core Web Vitals and SEO gains without ERP cutover.

Phase 3 — Incremental data & integrations: Migrate catalog segments, customer groups, or regions to ACCS using bulk migration tooling. Move integrations to App Builder one domain at a time (payments, then ERP, then OMS).

Phase 4 — Full ACCS cutover: Decommission PaaS infrastructure when extension parity is achieved and hypercare completes on all channels.

When to skip phases: Greenfield brands with no legacy extensions and under 5K SKUs can often jump directly to ACCS full migration.

Risk reduction: Each phase has independent rollback — Optimizer can be disabled without touching checkout; Edge Delivery pilots run parallel to Luma until metrics justify cutover.

Nexa TechnoLabs structures statements of work around these phases so boards see quarterly value, not a year of "migration in progress" with no revenue impact.
