Migration Services

Amazon Redshift to BigQuery Migration Services

Move Redshift data, SQL, pipelines, and analytical workloads to BigQuery through a structured migration designed to support data integrity, business continuity, and Google Cloud consolidation.

Amazon Redshift to BigQuery Migration services

Why BigQuery?

Create a Unified Google Cloud Analytics Platform

Serverless Analytics

Run analytical workloads without managing warehouse clusters or manually provisioning infrastructure.

Flexible Scalability

Scale storage and analytical compute independently as data volumes, concurrency, and query demand change.

Google Cloud Integration

Connect enterprise data with Looker, Vertex AI, Gemini, Dataflow, and other Google Cloud services.

Improved Cost Control

Use on-demand processing, capacity-based reservations, autoscaling, quotas, and workload monitoring to manage analytics spending.

How We Migrate

A Structured Amazon Redshift to BigQuery Migration

  1. 1

    Assess

    Review Redshift schemas, tables, data volumes, SQL, stored procedures, UDFs, pipelines, security, reports, workload patterns, and AWS dependencies.

  2. 2

    Design

    Define the BigQuery architecture, migration waves, data-transfer approach, security model, capacity plan, and validation criteria.

  3. 3

    Convert and Migrate

    Move schemas and data while translating Redshift SQL, procedures, transformations, pipelines, and integrations for BigQuery. Google Cloud supports Redshift SQL translation and automated schema and data transfer through BigQuery migration services.

  4. 4

    Validate

    Compare source and target data, query results, business calculations, reports, permissions, pipeline execution, and workload performance.

  5. 5

    Cut Over and Optimize

    Transition production workloads and optimize BigQuery capacity, reservations, queries, partitioning, clustering, and cost controls.

Why Codimite?

End-to-End Data Migration Expertise

Codimite combines Google Cloud expertise, data engineering, cross-cloud migration planning, workload conversion, and structured validation to support the complete migration journey.

Start Your Migration
  • Google Cloud Expertise. We build the target environment using BigQuery and the wider Google Cloud data ecosystem.

  • Cross-Cloud Planning. We plan AWS data movement, temporary staging, network connectivity, dependencies, and potential data-transfer costs.

  • Structured Validation. We verify data quality, business calculations, reports, security controls, and workload performance before production cutover.

  • Phased Migration. We reduce disruption by moving workloads in controlled waves instead of one large transition.

Platform Comparison

Amazon Redshift and BigQuery at a Glance

Both platforms support enterprise analytics, but BigQuery provides a more integrated, serverless approach for organizations building their data and AI environment on Google Cloud.

Area Amazon Redshift BigQuery
Platform model AWS cloud data-warehouse platform with provisioned and serverless options Fully managed, serverless cloud data warehouse
Infrastructure Infrastructure management varies between provisioned and serverless deployments Underlying infrastructure and platform maintenance managed by Google
Scaling Scaling depends on Redshift deployment, node configuration, and serverless capacity settings Storage and analytical compute scale independently according to workload demand
SQL Redshift SQL based on PostgreSQL with platform-specific features GoogleSQL designed for large-scale analytical workloads
Pricing Provisioned-node or serverless consumption pricing, plus applicable AWS data-transfer charges On-demand or capacity-based pricing with reservations and autoscaling options
Data distribution Distribution styles, distribution keys, sort keys, and node-based data placement Managed storage with partitioning and clustering controls
Optimization Sort keys, distribution keys, compression, vacuuming, statistics, and workload configuration Partitioning, clustering, materialized views, query optimization, and capacity management
Workload management Workload Management queues and serverless usage controls Reservations, assignments, slots, quotas, autoscaling, and workload isolation
AI and ML Integrates with AWS analytics and machine-learning services BigQuery ML with native integration across Vertex AI and Gemini
Business intelligence Integrates with Amazon QuickSight and third-party BI platforms Native alignment with Looker and support for third-party BI tools
Cloud ecosystem Closely integrated with AWS services Closely integrated with Google Cloud data, analytics, application, and AI services
Operations Operational responsibilities vary by provisioned or serverless configuration Infrastructure availability, scaling, maintenance, and platform updates managed by Google

FAQs

Amazon Redshift to BigQuery Migration FAQs

What can Codimite migrate from Amazon Redshift?

We can migrate schemas, tables, historical data, SQL, stored procedures, UDFs, pipelines, reports, security controls, and connected analytical workloads.

Can Redshift SQL be converted automatically?

BigQuery SQL translation tools can accelerate supported Redshift SQL conversion. Complex procedures, functions, and platform-specific logic still require engineering review and testing.

How is Amazon Redshift data moved to BigQuery?

BigQuery Data Transfer Service can unload Redshift data to an Amazon S3 staging bucket and transfer it into BigQuery. Other staged or custom transfer approaches may also be used depending on connectivity and data volume.

Do we need an Amazon S3 bucket during migration?

The managed Redshift transfer process uses an Amazon S3 bucket as a temporary staging area between Redshift and BigQuery.

How do you manage AWS data-transfer costs?

We estimate transfer volumes, avoid moving unnecessary data, minimize repeated cross-cloud reads, and plan migration waves around AWS egress and staging costs.

Can private Redshift instances be migrated?

Yes. Google Cloud documents a VPC-based migration approach for private Redshift instances using network connectivity between AWS and Google Cloud.

Can the migration be completed in phases?

Yes. Workloads can be grouped by data domain, business unit, priority, complexity, or technical dependency.

How do you validate migrated data?

We compare row counts, aggregates, business totals, query results, reports, permissions, pipeline execution, and workload performance.

Will existing BI reports continue to work?

Many BI tools support BigQuery, but connections, SQL, semantic models, or report calculations may require updates.

Is BigQuery always less expensive than Amazon Redshift?

Not necessarily. Cost depends on current Redshift commitments, serverless or provisioned usage, query patterns, concurrency, data transfer, and the selected BigQuery pricing model.

Can Redshift remain active during the migration?

Yes. Both environments can operate temporarily while data, queries, reports, and workload results are validated.
