Cloud Data Warehouse Migration - Redshift, Synapse, BigQuery & Legacy Platforms
Migrating to Snowflake is more than a technology upgrade. It is an opportunity to modernise data architecture, improve performance, simplify operations, and reduce the complexity associated with traditional data warehouse platforms. Because every warehouse platform has its own SQL dialect, optimisation model, and data structures, successful migration requires careful planning, validation, and transformation rather than a simple lift-and-shift approach.
Many organisations moving from Amazon Redshift, Azure Synapse Analytics, Google BigQuery, Teradata, Netezza, Oracle, or on-premise data warehouses face challenges related to SQL compatibility, ETL migration, data validation, and workload optimisation. Without a structured migration strategy, organisations risk extended downtime, reporting inconsistencies, and increased project costs.
SourceMash helps organisations migrate data, workloads, reports, and analytics processes to Snowflake through a proven migration framework covering assessment, SQL conversion, data transfer, validation, testing, and production cutover. Our approach minimises risk while ensuring business continuity throughout the migration journey.
