Summary

Migrate e-commerce platforms to AWS with zero inventory disruption. Holiday blackout-aware migration planning, POS integration continuity, and high-availability architecture for retail workloads.

Key Facts

  • • Migrate e-commerce platforms to AWS with zero inventory disruption
  • • Peak season (Black Friday, Cyber Monday, Christmas) represents 30-40% of annual revenue — any disruption is unacceptable
  • • POS & Third-Party Integration Preservation: E-commerce platforms integrate with POS systems, payment processors, 3PL providers, and marketplace APIs
  • • Retail Migration Calendar: Migration phases planned February-September, with infrastructure preparation Q1, data migration Q2, and cutover Q3
  • • Lambda-based reconciliation detects and resolves any discrepancies before traffic cutover

Frequently Asked Questions

How do you migrate a Magento or Shopify Plus store to AWS?

For Magento: we migrate the MySQL database to RDS Aurora, the media library to S3/CloudFront, the application to ECS or EC2 Auto Scaling, and Redis sessions to ElastiCache. For Shopify Plus: the platform itself stays on Shopify, but we migrate headless commerce frontends, custom integrations, and data analytics workloads to AWS.

What happens to our CDN and image URLs during migration?

We configure CloudFront as the new CDN and migrate images to S3. Using CloudFront origin rewrites or Lambda@Edge, we preserve all existing image URLs — product pages, emails, and cached Google Images continue to work without URL changes. The cutover is invisible to end users and search engines.

How do you validate inventory accuracy after migration?

We run dual-write with automated reconciliation for 48-72 hours before cutover. A Lambda reconciliation job compares inventory counts between source and target at the SKU level every 15 minutes and flags any discrepancies. Cutover only proceeds when zero discrepancies exist across a 4-hour clean window.

Key Challenges We Solve

Holiday Blackout Periods

E-commerce platforms cannot be migrated between October and January. Peak season (Black Friday, Cyber Monday, Christmas) represents 30-40% of annual revenue — any disruption is unacceptable.

Inventory System Continuity

Real-time inventory counts must remain accurate across all channels during migration. Any gap between source and target inventory data can result in overselling and customer fulfillment failures.

POS & Third-Party Integration Preservation

E-commerce platforms integrate with POS systems, payment processors, 3PL providers, and marketplace APIs. Each integration must be validated and preserved during migration.

Product Image & Media Migration

Product catalogs contain millions of images in multiple sizes and formats. CDN migration must preserve image URLs or update them globally without breaking existing product links.

Our Approach

Retail Migration Calendar

Migration phases planned February-September, with infrastructure preparation Q1, data migration Q2, and cutover Q3. October-January is reserved for peak season operations on the stable target platform.

Dual-Write Inventory Sync

During migration, inventory updates write to both source and target systems simultaneously. Lambda-based reconciliation detects and resolves any discrepancies before traffic cutover.

Media Migration to CloudFront + S3

Product images migrated to S3 with CloudFront distribution, URL rewriting at the CDN layer to preserve existing product image URLs — no database updates required for image paths.
