Unique Aspects of Business-led Migration Involving Multiple Systems

Unique challenges arise during business-led data migration in an end-to-end scenario when the target is not a single application but a group of five to 10 B/OSSs.

Here are some of the possible issues:

Understanding the difference between business-led migrations that follow the end-to-end business process flow in a new multi-stack and technical migrations that insert or upsert data into target entities of each target application.

Recreating an optimized customer profile (including attributes, new offerings, and rationalized as well as optimized plans) for the new stack without replicating legacy data

Migrating to a progressively evolving digital platform with phased capability releases using a product catalog or a business process led migration strategy

Retaining historical data by making it available to the data warehouse for regulatory requirements without moving it to the new stack

Following the entire process flow across various components, IT platforms, or applications for migrating a single customer

Best performance of migration is limited by the worst performance of the component that is part of the migration process flow

The speed of migration is determined by the operational challenges arising from last minute changes made by the customer in the legacy stack

The focus in the new stack is on customer stability before picking the next cohort or eligible batch for data
