5 Essential Questions to Master Your Snowflake Migration

Migrating to Snowflake is a strategic move, but without data observability, it's a risky one. Data engineers, architects, and analytics leaders must ensure data reliability, performance, and cost-efficiency at every stage. Too often, migrations are blind lifts, riddled with pipeline breaks, quality issues, and budget overruns.

Acceldata, the industry's leading All-in-One Enterprise Data Observability, now evolving to Agentic Data Management, platform empowers teams to take control of their migration journey. With full-stack visibility and autonomous actions into data pipelines, compute platforms, cost governance, and data quality, Acceldata ensures your Snowflake deployment is faster, smarter, and future-proof.

1. Do You Have Full Visibility Into Your Data Landscape—Before You Migrate?

Before you migrate, you need a clear, actionable map of your data estate:

• Which pipelines and sources are critical to migrate?
• Where are the performance bottlenecks and silent failures?
• Are you migrating dormant or unused tables?

Acceldata Power Play:
Use Acceldata's intelligent dashboards and lineage capabilities Data Graph to generate an interactive map, visualize pipeline health, and isolate underused assets—so you're not just migrating everything, but only what matters.

✅ Reduce unnecessary storage and compute costs
✅ Avoid cascading failures by surfacing fragile dependencies
✅ Create an inventory of certified datasets for clean migration planning

2. Can You Reconcile Data Between Legacy and Snowflake Platform With Precision?

Modern data stacks require evidence-based migrations:

• Are you tracking query latency and resource utilization across platforms?
• Can you test Snowflake workloads against legacy performance baselines?
• How are you managing dual environments during transition?

Acceldata Power Play:
Acceldata enables data teams to certify data at the source like Teradata, MySQL, Spark, and further reconcile it at the destination, like Snowflake.

✅ Validate workload improvements with operational metrics that matter
✅ Maintain SLA fidelity across coexisting systems
✅ Avoid "black box" migration surprises

3. Are You Set Up to Optimize Snowflake Costs at Scale?

Moving to Snowflake opens up performance—but without guardrails, costs can spiral:

• Do you understand compute spend by workload, user, and team?
• Are you catching inefficient joins, cartesian products, and long-running queries?
• Can you identify when autosuspend or scaling policies are misfiring?

Acceldata Power Play:
Acceldata's Cloud Cost Insights monitors warehouse and query-level cost consumption. Get alerts on spend anomalies, unused clusters, and cost hotspots across teams.

✅ Cut unnecessary compute by 25%+ with workload tuning
✅ Optimize warehouse sizing and runtime policies
✅ Build cost transparency into your DataOps culture

4. Is Your Data Quality Bulletproof Before, During, and After Migration?

Bad data undermines every migration—and every downstream decision:

• Are you detecting schema changes, null surges, and row count mismatches?
• Can you automatically validate data after pipeline runs?
• Are data issues being caught before reaching business teams?

Acceldata Power Play:
Acceldata's Data Quality engine applies adaptive AI anomaly detection and customizable rules to catch quality failures before they impact Snowflake. Pre- and post-migration validation workflows ensure every record is trusted.

✅ Monitor freshness, volume, nulls, and drift automatically
✅ Run validation tests as part of pipeline CI/CD
✅ Deliver trusted data to downstream analytics consumers

5. Can You Align Teams Around Lineage, Policy, and Operational Governance?

A successful migration requires more than tech—it needs organizational alignment:

• Do engineering, analytics, and data governance teams share a single source of truth?
• Are lineage, access, and retention policies transparent and enforced?
• Can stakeholders collaborate around issues, KPIs, and remediation?

Acceldata Power Play:
Acceldata integrates with select catalogs, access policies, and metadata systems to drive shared operational context. With lineage, health dashboards, and role-based views, teams stay in sync—even as architecture shifts.

✅ Enable policy-aware migration planning
✅ Visualize lineage from source to insight
✅ Reduce MTTR for data issues with cross-team collaboration

Final Word: Don't Just Migrate. Modernize Intelligently.

Snowflake gives you scalability. Acceldata gives you trust, control, and agility. Whether you're moving from Teradata, Netezza, Hadoop, or on-prem SQL engines, Acceldata ensures your migration is:

• Faster with automated diagnostics and baseline reporting
• Smarter with near real-time cost, quality, and performance analytics
• Sustainable with proactive alerts and continuous observability

Why fly blind when you can migrate with telemetry?
