Korea Digital Platform Migration

Cutover project that moved orders, identity linkage, and data flows to the global standard

Project Overview

Migration project that transitioned Korea order, data, and messaging flows to the global standard while linking legacy user accounts to new global platform accounts through a shared user identifier so historical orders remained accessible after cutover. The same stream also stabilized legacy order history and post-purchase operations after go-live.

Challenge

The challenge was not only moving five years of order data on schedule, but also preserving account linkage, product consistency, clickstream continuity, and post-cutover legacy order operations at the same time.

Solution

Account-mapping-based order migration model

Designed the migration around a shared user identifier so order history remained valid under the new global account structure.

Designed the shared user identifier-based account linkage model

Implemented batch jobs for order transformation and linkage

Reduced migration processing time through performance testing

Built validation and operational plans aligned to cutover timing

Post-cutover legacy order and post-purchase integration

Organized the follow-up integration so historical order lookup, CS access, returns, and delivery status sync continued after cutover.

Connected legacy order lookup for nike.com

Handled about 20K additional order linkage tasks after cutover

Integrated CS lookup systems

Designed and operated returns and delivery-status synchronization

Tech Stack

Key Results

Completed cutover on 2022-10-04

Built migration structure for about 20M historical orders

Reduced migration processing time to about 3.5 days

Stabilized legacy order history and post-purchase operations after cutover

Learnings

Large migrations often hinge more on account-linking design than raw data movement

Cutover quality depends on performance, validation logic, and operational planning together

Product consistency and communication risks must be handled as part of the migration itself

Accurate structural framing increases credibility in public-facing case studies
