CIBC Canada
The Challenges
CIBC aimed to modernize its enterprise data infrastructure by migrating from a legacy Netezza appliance to the scalable, cloud-native Amazon Redshift platform. The project demanded an in-depth understanding of existing schemas, high data quality expectations, and a zero-tolerance policy for downtime or data loss.
- Migrating large volumes of transactional and reference data.
- Ensuring seamless compatibility across systems during cutover.
- Establishing a repeatable, automated quality assurance process.
- Delivering on a tight timeline with minimal business interruption.
Business Impact
- 45 TB of data migrated with <0.01% deviation.
- 98% faster ad hoc query performance post-migration on Redshift.
- Zero downtime for business-critical apps during migration.
- 3× faster audit readiness due to automated QA validation.
- Cut data preparation time by 40% for internal analytics teams productivity via standardized access and definitions.
Our Solution
We began a high-precision data migration initiative, combining cloud engineering, data profiling, and validation frameworks to ensure an accurate and efficient transition.
Data Mapping & Profiling
Conducted profiling across 1,500+ tables to analyze column-level metadata, cardinality, null distributions, and foreign key relationships.
Cloud Migration
Migrated over 45 TB of structured data from Netezza to Amazon Redshift,ensuring schema compatibility, data type transformation, and performance tuning.
Discovery & Classification
Built a data discovery layer that automatically flagged anomalies in 3.2% of records, addressed before live cutover.
Quality Assurance Framework
Designed validation scripts to perform row counts,checksums, and transformation audits, reducing post-migration defect rate to <0.01%.
Delta Testing
Implemented delta-load mechanisms and rollback strategies for seamless transition,with zero critical incidents reported during the go-live phase.
