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.

Your 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Break Free from Outdated Infrastructure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

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

Untangle Complex Legacy Code

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

Advantages of the Migration from Netezza to Snowflake

Elastic compute separates storage from processing, letting teams scale without capacity planning.

Pay-for-use pricing cuts idle costs, unlike Netezza’s fixed hardware footprint.

Built-in data sharing, governance, and security remove the friction of external tools.

Zero-maintenance cloud architecture frees engineers from patching, upgrades, and tuning

Our Fixed Proven Process

We keep the migration process straightforward, transparent, and risk-free. Without endless scoping cycles or vague budgets. Just a clear plan, a fixed price, and an agreement to get it done.

Frequently asked question

Data analytics services involve collecting, processing, and analyzing data to uncover patterns, trends, and insights that help businesses make informed decisions. These services can include data engineering, business intelligence (BI), predictive analytics, and machine learning implementation.

Data analytics helps businesses identify opportunities, optimize operations, reduce costs, and improve customer experiences. By using advanced tools and AI-driven models, companies can predict trends, detect anomalies, and act on real-time insights to gain a competitive edge.

Data science focuses on building models and algorithms to make predictions or automate decisions, often using machine learning and AI techniques. Data analytics typically refers to the process of examining datasets to extract meaningful insights, often using BI tools, dashboards, and reporting systems.

A single source of truth is a centralized, trusted data repository that ensures everyone in an organization uses the same accurate and up-to-date information for decision-making. SSOT eliminates discrepancies, reduces errors, and improves collaboration across teams.

Machine learning and AI enhance data analytics by automating data processing, identifying hidden patterns, and generating predictive insights. These technologies allow businesses to act proactively rather than reactively, improving decision-making speed and accuracy.

The timeline depends on project complexity. A basic BI dashboard might take a few weeks, while enterprise-scale data platforms with AI integration can take several months. Agile delivery approaches often provide early value within the first 6–8 weeks.

Key trends include real-time analytics, AI governance and compliance, data mesh architecture, multi-cloud data strategies, and the integration of generative AI into BI platforms. Businesses are focusing on trustworthy, explainable insights rather than just big data volume.
