Data Warehouse Modernisation
Replace Legacy Warehouses with Cloud-Native Analytics
What we do
Legacy on-premise data warehouses — Teradata, SQL Server PDW, Netezza, or Oracle OLAP — are expensive to maintain and bottlenecked by hardware. We migrate your data warehouse to Azure cloud-native services, preserving your business logic while dramatically improving performance, cost, and agility.
Ideal for
Organisations running expensive on-premise data warehouses who want to reduce cost, improve performance, and enable self-service analytics
Common applications
On-Premise to Cloud Migration
Migrate schemas, stored procedures, ETL jobs, and historical data from legacy DW to Azure Synapse or Microsoft Fabric.
SQL Server DW Modernisation
Lift-and-shift SQL Server data warehouses to Azure SQL Managed Instance or modernise to Synapse Analytics.
Reporting Layer Rebuild
Replace SSRS/Crystal Reports with Power BI Direct Lake dashboards connected to the modernised warehouse.
Consolidation of Multiple DWs
Merge multiple siloed data warehouses into a single Azure platform, resolving conflicting definitions and duplication.
Performance Optimisation
Tune distribution keys, materialised views, and query plans for sub-second query response on large fact tables.
Decommission & Cost Reduction
Plan and execute the decommission of legacy hardware licences once the cloud warehouse is validated in production.
How we work
DW Assessment
Analyse schemas, query workloads, ETL dependencies, and data volumes to scope and sequence the migration.
Migration Planning
Design the target architecture, mapping source objects to cloud-native equivalents. Identify transformation complexity.
Phased Migration
Migrate in phases — validate data accuracy and performance at each stage with automated reconciliation checks.
Cutover & Decommission
Execute production cutover during a maintenance window, then plan the decommission of legacy hardware.
What you receive

- Migrated schemas, business logic, and historical data
- Automated reconciliation reports confirming data accuracy
- Power BI connected to the new warehouse
- Performance benchmark report vs. legacy
- Decommission plan and cost savings projection
