The Complete Shopify Plus Migration Checklist
Successful Shopify Plus migration requires methodical planning. Follow this proven checklist to minimize risk and protect revenue.
Pre-Migration Planning
1. Audit Your Current Platform
Export and document:
- Product catalog (variants, SKUs, collections)
- Customer data (accounts, order history, lifetime value)
- Order history and transaction records
- URL structures and high-performing pages
- Custom functionality and integrations
- Blog content and media assets
2. Define Migration Scope and Success Metrics
Determine:
- Must-have vs. nice-to-have features
- Custom functionality requirements
- Headless vs. traditional storefront architecture
- Integration requirements (ERP, CRM, 3PL, payment gateways)
- Success KPIs (conversion rate, page speed, SEO traffic, revenue)
3. Plan SEO Preservation Strategy
- Create a comprehensive URL redirect map (301 redirects). Missing redirects are the #1 cause of SEO traffic loss
- Document metadata for all pages
- Validate canonical tags and structured data
- Prepare XML sitemap for resubmission

6. Implement Checkout Customization
- Build checkout extensions using Checkout Extensibility

Launch and Post-Migration

Checkout Extensibility Replaces checkout.liquid
Shopify replaced checkout.liquid in August 2024, making Shopify Checkout Extensibility migration essential for all new Shopify Plus stores. New migrants immediately gain access to:
- Code-free checkout customization through the checkout editor
- App-based extensions that are upgrade-safe
- Higher conversion rates with integrated Shop Pay
- Custom checkout UI extensions for bespoke experiences
Headless Architecture Adoption
In 2023, 63% of retailers planned to adopt headless architecture. By 2026, headless Shopify Plus migration has become increasingly common for brands requiring extreme customization, omnichannel content delivery, and 20-50% faster page loads. Shopify’s Hydrogen and Oxygen frameworks simplify headless builds with React-based storefronts and global CDN delivery.
AI-Driven Ecosystem and Predictive Analytics
Post-migration, Shopify Plus merchants gain AI-powered features unavailable on legacy platforms:
- Agentic Storefronts discoverable in ChatGPT, Microsoft Copilot, and Google AI Mode
- Predictive analytics for demand forecasting and inventory optimization
- AI-powered personalization with customer-specific catalogs and pricing
- Automated marketing insights analyzing cross-channel customer behavior
With 71% of companies now using generative AI in at least one business function, migrating to a platform with built-in AI capabilities is a competitive requirement.
Native B2B Functionality
B2B ecommerce is projected to reach $36 trillion by 2026 with a 14.5% CAGR. Shopify Plus now includes native B2B features, such as customer-specific pricing, flexible payment terms (net 30, net 60), self-service portals, and company management. This eliminates the need for separate wholesale stores. B2B brands report 40% increases in average customer spend and 25% reductions in administrative tasks post-migration.

Shopify Plus migration in 2026 is a strategic transformation that positions your brand for AI-driven, headless, omnichannel commerce with native B2B capabilities, enhanced checkout customization, and 29% lower total cost of ownership compared to legacy platforms.
