Case Study: a media company strengthens analytics migration assurance with QEagle's cloud lakehouse validation

a media company reduces testing effort by 50% with QEagle

A media company faced significant challenges migrating its multi-terabyte historical analytics and hundreds of reports from a legacy warehouse to a cloud lakehouse. The difficulties included reconciling complex historical data and slowly changing dimensions while maintaining report continuity throughout the phased migration. QEagle was engaged to provide end-to-end source-to-target assurance for this complex data migration.

QEagle implemented an automated validation strategy that included history, dimension, aggregate, and dashboard parity checks. Their solution automated record, field, and relationship integrity checks and validated transformations and exception handling. This approach reduced primary testing and operational effort by an estimated 50%, improved confidence in the migration, and enabled faster defect isolation. QEagle's work also created repeatable controls for subsequent migration domains.
