Snowflake Solution

Redshift to Snowflake Migration

Stop managing clusters. Start scaling data.

We migrate your Amazon Redshift warehouse to Snowflake — schema conversion, data transfer, pipeline rewiring, and validation — so you get time travel, zero-copy cloning, elastic compute, and true environment isolation without months of downtime or risk.

The Problem

Redshift is holding your data team back

Organizations running Amazon Redshift hit operational walls that slow down engineering, inflate costs, and block modern data practices.

No Time Travel

Redshift lacks built-in time travel — recovering from accidental deletes or bad deployments means restoring from manual snapshots, costing hours of downtime and engineering effort every time.

Dedicated Instance Upgrades

Scaling Redshift means upgrading to larger dedicated clusters — expensive, disruptive, and requiring downtime. You pay for peak capacity 24/7, even when workloads are idle.

No Zero-Copy Cloning

Need separate dev, test, and production environments? With Redshift, that means duplicating entire clusters — doubling or tripling storage costs and creating drift between environments.

Why Snowflake

What Snowflake gives you that Redshift can't

Snowflake's architecture eliminates the operational pain points that make Redshift expensive and inflexible at scale.

Time Travel built-in

Query any table as it existed at any point in time — up to 90 days. Recover from accidental deletes, audit changes, and debug data issues without restoring snapshots.

Zero-Copy Cloning

Instantly spin up dev, test, and production environments without duplicating data. Pay only for the changes — not the entire dataset. Environment isolation in seconds, not hours.

Elastic, independent scaling

Scale compute up or down instantly — no cluster resizing, no downtime. Storage and compute are fully separated, so you only pay for what you use, when you use it.

Pay-per-second pricing

Snowflake charges per second of compute — warehouses auto-suspend when idle. No more paying for 24/7 dedicated clusters when your workloads run for a few hours a day.

How We Migrate

From Redshift to Snowflake in three phases

A structured migration approach that minimises downtime and ensures zero data loss.

Phase 1
Weeks 1–2
Assessment & Migration Planning
Audit existing Redshift schema, stored procedures, UDFs, and data types
Map all ETL pipelines, BI tool connections, and downstream dependencies
Define the Snowflake target architecture — warehouses, roles, and environment strategy
Deliverables
Schema compatibility report with conversion gaps
Pipeline dependency map
Migration runbook with rollback plan
Phase 2
Weeks 3–6
Schema Conversion & Data Migration
Convert Redshift DDL, views, stored procedures, and UDFs to Snowflake SQL using automated tooling + manual review
Migrate historical data via S3 UNLOAD → Snowflake COPY INTO with parallel batch loading and validation
Set up Snowflake environments — dev, test, prod — using zero-copy cloning for instant isolation
Deliverables
Converted schema deployed in Snowflake
Historical data migrated and validated
Dev/test/prod environments live via zero-copy clones
Phase 2
Weeks 3–6
Schema Conversion & Data Migration
Convert Redshift DDL, views, stored procedures, and UDFs to Snowflake SQL using automated tooling + manual review
Migrate historical data via S3 UNLOAD → Snowflake COPY INTO with parallel batch loading and validation
Set up Snowflake environments — dev, test, prod — using zero-copy cloning for instant isolation
Deliverables
Converted schema deployed in Snowflake
Historical data migrated and validated
Dev/test/prod environments live via zero-copy clones
Phase 3
Weeks 7–10
Pipeline Cutover & Validation
Rewire ETL/ELT pipelines to point to Snowflake — Airflow, dbt, Glue, or Fivetran
Run parallel environments — Redshift and Snowflake side by side — with automated data parity checks
Reconnect BI tools (QuickSight, Looker, Tableau) and validate dashboards against Snowflake
Deliverables
All pipelines running on Snowflake
Data parity validated with less than 1% variance
Redshift decommission plan and cost savings report

What You Get

Your Snowflake platform — production-ready from day one

Every migration we deliver goes beyond lift-and-shift — we optimise for Snowflake's architecture so you get the full benefit from week one.

Environment Isolation

Dev, test, and production environments via zero-copy clones — each with its own roles, permissions, and data access controls. No cross-environment contamination.

Time Travel & Recovery

Up to 90 days of time travel on every table — query historical data, undo accidental changes, and audit pipeline outputs without manual snapshot management.

Elastic Compute

Snowflake virtual warehouses scale up and down on demand — auto-suspend when idle, auto-resume on query. No cluster management, no capacity planning.

Multi-Cloud Flexibility

Snowflake runs on AWS, Azure, and GCP — no vendor lock-in. Share data across clouds and regions without moving it.

Cost Optimisation

Pay-per-second compute, auto-suspend warehouses, and resource monitors built in from day one — so you see immediate cost savings over Redshift reserved instances.
