Key challenges included maintaining zero downtime during migration and ensuring regulatory compliance. The article provides actionable strategies for batch data migration, including data validation and rollback procedures. For data engineers and architects, this offers a real-world blueprint for similar projects in regulated environments. The commercial value is high given the global trend toward data sovereignty and local infrastructure.
