Migrate Legacy Databases to Modern Cloud Without Losing a Record
Zero-downtime ETL migrations to Snowflake, BigQuery, and Redshift. Senior data engineer, not outsourced team. Creator of the QuickETL open-source framework.
Data Migration Gone Wrong Costs More Than Money
The Horror Stories
- "We were down for 3 days during migration"
- "Lost 6 months of customer data"
- "The new system was slower than the old one"
- "Integrations broke and nobody noticed for weeks"
How We Do It
- Zero downtime - business keeps running
- Validated integrity before cutover
- Performance tested under load
- Instant rollback if anything fails

What Sets Us Apart
Open-Source Contributor
Created QuickETL, an open-source ETL framework used by data teams worldwide. We don't just implement migrations. We build the tools.
Battle-tested patterns from real production environments.
100% Data Validation
Every row validated. Every transformation verified. Checksums at every stage. We don't cut over until we can prove the data matches exactly.
No Hidden Costs
Transparent, project-based pricing. We scope accurately upfront. No change orders, no scope creep surprises. If something takes longer than expected, that's on us.
Senior Engineer, Direct Access
You work directly with a senior data engineer, not an account manager who relays messages to junior developers. Faster decisions, fewer miscommunications.
Specialized Migration Services
Deep expertise in specific migration patterns and platforms.
Zero-Downtime Migration
Our signature methodology for migrating production databases without interrupting business operations.
Snowflake Migration
Specialized expertise in migrating to Snowflake's cloud data platform, including data modeling and optimization.
Legacy Modernization
Transform outdated systems into modern, maintainable architectures while preserving business logic.
Every Migration, Every Time
Zero Data Loss
100% validation at every stage. Row counts, checksums, business logic verification. We don't cut over until every record is accounted for.
Minimal Downtime
Parallel run architecture means your production system stays online during migration. Cutover measured in minutes, not hours or days.
Instant Rollback
Every migration includes a tested rollback plan. If anything goes wrong post-cutover, we can switch back immediately.
Clear Documentation
Runbooks, architecture diagrams, and knowledge transfer. Your team understands the new system when we're done.
Case studies available upon request during consultation.
Zero-Downtime Migration Process
How we move your data without stopping your business.
Parallel Environment Setup
We set up the new system alongside the old one. Both run simultaneously during migration - no "maintenance window" required.
Initial Data Sync
Bulk historical data moves first while your production system continues operating normally. Users don't notice anything.
Change Data Capture
Real-time replication catches changes as they happen. The new system stays in sync with production throughout migration.
Validation & Testing
Automated checksums verify data integrity. We run parallel queries comparing old and new systems until we're confident everything matches.
Cutover
When validated, we switch traffic to the new system. Typically takes minutes, not hours. If anything goes wrong, we can switch back instantly.
Common Migration Paths
| From | To | Timeline | Complexity |
|---|---|---|---|
| Legacy SQL Server / Oracle | PostgreSQL / Cloud SQL | 6-12 weeks | Medium-High |
| Spreadsheets / Access | Proper database + UI | 4-8 weeks | Medium |
| On-prem data warehouse | Snowflake / BigQuery | 8-16 weeks | High |
| Flat files / FTP | Real-time pipelines | 4-8 weeks | Medium |
How We Mitigate Migration Risks
Data Loss
Checksums at every stage, parallel running until validated, instant rollback capability
Extended Downtime
Zero-downtime methodology with CDC replication - cutover measured in minutes
Broken Integrations
API compatibility layers, phased migration of dependent systems, thorough integration testing
Performance Issues
Load testing before cutover, query optimization, hardware right-sizing
Migration Pricing
Project-based pricing. No hourly surprises.

Standard Migration
Single database or system migration with full support
Enterprise Migration
Multiple systems, complex integrations, extended support
Migration Questions
It means your business keeps running normally during migration. Users can continue working while we move data. The cutover itself typically takes 5-15 minutes, and even that can be done during off-peak hours. If anything goes wrong, we can switch back to the old system instantly.
