Faster Cloud Migration Powered by Reusable Frameworks

The client needed a scalable, automation-led approach to migrate large volumes of enterprise data from on-premise systems to Google Cloud across 30+ countries. Their teams were operating with fragmented processes, manual infrastructure provisioning, and limited reuse across regions, slowing down migration timelines. They also needed to standardize how historical data was moved, validated, and reconciled so every market could adopt the same model with confidence.

In addition, the client required an automated way to leverage their existing OneTru Solution Canvas to accelerate implementation. They wanted reusable ingestion patterns, a CDC-based replication pipeline for real-time data movement, and a consistent framework that would ensure accuracy, compliance, and faster execution during both Day-0 historical migration and Day-1 ongoing replication.
Ascendion designed a highly configurable, reusable automation layer powered by the OneTru platform, enabling rapid rollout of data migration and replication across all markets. The solution introduced standardized widgets that could be reused globally with minimal customization, making deployments faster and more predictable. 
We established a global EDS mapping and indexing strategy to ensure consistent data quality across regions. Historical datasets were migrated from on-prem systems into GCP databases as part of the Day-0 migration. On Day-1, a CDC-enabled pipeline replicated and transformed real-time EDS data, ensuring continuous synchronization after the initial cutover. 
With easy-to-enhance configurations and reusable ingestion frameworks, the client gained the ability to roll out solutions quickly, adapt to regional variations, and maintain standardization without rebuilding components.
