Accelerate migration of legacy data warehouses to Snowflake on AWS using a gated, validation-driven approach, delivered by certified SnowPro architects.
Overview
A data warehouse migration is only as reliable as the validation built into it. TEKsystems Global Services (TGS) migrates enterprise workloads from Teradata, Oracle, Netezza and on-premises SQL Server to Snowflake on AWS through a gated methodology where each phase closes with defined exit criteria, source-to-target validation and documented rollback before the next begins. The delivery architecture uses Amazon S3 for data staging, AWS Database Migration Service for extraction, AWS PrivateLink for secure connectivity and AWS CloudFormation for repeatable provisioning. This structured, automation-enabled framework enables organizations to modernize faster, reduce operational disruption, and unlock the full performance and scalability of Snowflake on AWS.
What’s Included
- Source system inventory and complexity scorecard across all in-scope database objects, pipelines and downstream dependencies.
- Snowflake target architecture with warehouse strategy, security model and AWS PrivateLink connectivity.
- TCO projection benchmarked against legacy platform costs.
- Schema conversion and ETL/ELT pipeline migration to AWS Glue, dbt or Snowflake-native tasks.
- Source-to-target data migration with validation via row counts, checksums and query result comparison.
- Cutover execution with parallel production runs, rollback procedures and operations handoff runbook.
How It Works
- Assessment: Source system discovery, complexity scoring, TCO modeling and a phased migration roadmap. Stands alone as a planning deliverable or credits toward execution.
- Migration Execution: Sprint-based schema conversion, pipeline migration, AWS infrastructure deployment with Amazon S3 staging and AWS Lambda orchestration, iterative validation, parallel runs and cutover.
- 90-Day Optimization: Warehouse sizing recommendations, query performance baselining, Snowflake resource monitor configuration and monthly reviews transitioning into steady-state operations.
