Move from Netezza to Snowflake with Zero Budget Surprises
Migrating from IBM Netezza to Snowflake often feels risky: complex rewrites, hidden performance gaps, unpredictable costs. Sphere makes it predictable.
We plan and execute your migration under a fixed cost model, so you know exactly what it takes to get there — and what you get on the other side.
Get the OfferYour Value From Migration
Netezza powered enterprise analytics for years, but it was built for a different era. As workloads grow and teams demand faster insights, its rigid infrastructure starts slowing everything down. Migration to Snowflake promises agility and lower costs, yet most projects hit unexpected roadblocks, tangled legacy code, data quality issues, and months lost chasing performance parity.
Break Free from Outdated Infrastructure
Legacy Netezza hardware becomes a bottleneck long before the migration is done. We plan around it, keeping workloads stable while we move them.
Pain points we solve:
- Rising costs to maintain legacy appliances
- Hardware reaching end-of-support
- Capacity limits blocking analytics growth
Untangle Complex Legacy Code
Tangled Netezza-specific SQL and stored procedures derail most timelines. We untangle and refactor them with automated tooling and expert oversight.
Pain points we solve:
- Platform-locked code that resists refactoring
- High effort for manual rewrites
- Frequent errors when replicating logic
Deliver Performance Users Can Trust
Post-migration workloads often fail at scale. We run parallel tests and tune for parity before go-live, so users never see a drop.
Pain points we solve:
- Unpredictable performance post-migration
- Incomplete testing leads to production issues
- Business teams forced to fall back to old systems
