Proven SQL Server to Redshift migration by senior engineers
How to migrate Microsoft SQL Server to Amazon Redshift? It starts with a fixed-scope project run by senior platform engineers. We assess your SQL Server data warehouse, then move it to Redshift with correct distribution
The lowest-cost way off Microsoft SQL Server: our migration tooling automates the repetitive work —you pay senior engineers for judgment, not keystrokes.
How we support Microsoft SQL Server → Amazon Redshift after migration
- ✓Fixed scope with senior engineers – no surprises.
- ✓Optimized distribution and sort keys from day one.
- ✓Vendor support stays active while you plan the move.
- ✓Scale Redshift compute independently of storage.
- ✓40–70% savings on legacy support during transition.
Exceeded resource capacity on SQL Server
Your on-premises instances hit CPU or I/O limits. Morning reports crawl. Redshift’s MPP architecture handles your growing data without forklift upgrades.
Unacceptable report latency for executives
Executives need real-time dashboards, but SQL Server batch queries take hours. Our migration restructures your workload for columnar speed.
Unoptimized ETL loops and temp-table reliance
SSIS loops designed for row-based loading break under Redshift. Heavy temp-table usage causes performance cliffs. We rewrite those patterns for bulk columnar loads.
Microsoft SQL Server → Amazon Redshift migration — your questions answered
Does Microsoft SQL Server stay supported during the move?+
Yes. Your existing vendor contract remains active. You migrate on your timeline – no forced big-bang cutover. If the contract later lapses, our third-party support covers most operational issues on the legacy platform while you finish.
Are cursor-based queries a problem on Redshift?+
Cursors in SQL Server often assume single-row processing, which clashes with Redshift’s columnar MPP engine. We re-express cursor logic as set-based operations during migration, restoring performance.
How do you handle SSIS ETL loops?+
SSIS loops built for row-by-row inserts are rewritten for bulk COPY commands and staging tables. We optimize distribution keys first so loads run efficiently from day one.
What about heavy temp-table usage in complex queries?+
Redshift supports temp tables, but overuse can cause excessive data redistribution. We redesign queries to leverage distribution keys and sort orders, reducing temp-table dependency and improving query speed.
Move with confidence – fixed scope, senior engineers
Beyond migration, we provide ongoing Amazon Redshift monitoring, scaling optimization, and automated ELT orchestration support. Start with a no-obligation Redshift architecture and key distribution assessment.
