ETL vs ELT Architecture
Traditional ETL
❌ Slow processing on limited ETL servers
❌ Expensive infrastructure maintenance
❌ Complex deployment and versioning
Modern ELT
✅ 80% faster with cloud warehouse power
✅ 70% cost savings, no ETL servers
✅ Git-based version control and CI/CD
4-Phase Migration Process
ETL Analysis
AI analyzes your existing ETL jobs to understand transformation logic, dependencies, and data flows.
- Automated ETL job inventory and analysis
- Dependency mapping and lineage tracking
- Transformation logic extraction
ELT Conversion
AI converts ETL logic to modern ELT using SQL, dbt, and cloud-native tools.
- 95% automated conversion to SQL/dbt
- Orchestration setup (Airflow/Prefect)
- Data quality validation rules
Parallel Testing
AI runs ETL and ELT in parallel with automated validation to ensure identical results.
- Dual-run validation with reconciliation
- Performance benchmarking and optimization
- Data quality verification
Cutover & Decommission
AI orchestrates phased cutover to ELT and decommissions legacy ETL infrastructure.
- Phased cutover with rollback capability
- ETL server decommissioning
- Documentation and knowledge transfer

People Also Ask
What is the difference between ETL and ELT?
ETL (Extract, Transform, Load) transforms data on separate ETL servers before loading to the warehouse. ELT (Extract, Load, Transform) loads raw data first, then transforms it using the cloud warehouse's processing power. ELT is 80% faster and 70% cheaper by eliminating ETL servers and leveraging scalable cloud compute.
How does AI convert ETL jobs to ELT?
AI analyzes your ETL jobs (SSIS, Informatica, Talend) to extract transformation logic, then automatically generates equivalent SQL or dbt code that runs in your cloud warehouse. It handles 95% of conversions automatically, including complex transformations, lookups, and aggregations, with human review for the remaining 5%.
Can I migrate from SSIS to ELT?
Yes, AI can convert SSIS packages to modern ELT using SQL and dbt. It extracts transformation logic from SSIS data flows, control flows, and expressions, then generates equivalent cloud-native code. The migration includes automated testing to ensure identical results between SSIS and ELT.
How long does ETL to ELT migration take?
With AI-powered automation, most migrations complete in 2-3 weeks including analysis, conversion, testing, and cutover. Manual migrations typically take 3-6 months. Timeline depends on the number of ETL jobs, complexity of transformations, and data volume.
What are the cost savings of migrating to ELT?
Organizations see 70% infrastructure cost savings by eliminating ETL servers and licensing fees. Processing is 80% faster using cloud warehouse compute. Migration costs are also 75% lower with AI: $50K-$100K vs $200K-$400K for manual migration. Total 3-year TCO is typically 60-70% lower with ELT.
