4-Phase Migration Process

1

Data Lake Analysis

AI analyzes your data lake structure, file formats, and usage patterns to design optimal warehouse schema.

  • Automated data profiling and quality assessment
  • Usage pattern analysis for optimization
  • Star/snowflake schema design
2

Schema & ETL Design

AI generates optimized warehouse schema and automated ETL pipelines for data transformation.

  • Dimension and fact table creation
  • Automated ETL pipeline generation
  • Data quality rules and validation
3

Phased Data Migration

AI migrates data in phases with continuous validation and zero downtime dual-run approach.

  • Historical data backfill with optimization

People Also Ask

When should I migrate from data lake to data warehouse?

Migrate when you need faster query performance for analytics, better data governance, or when your BI tools struggle with data lake complexity. Common triggers include slow dashboard performance, difficulty maintaining data quality, or need for structured reporting.

How does AI optimize warehouse schema design?

AI analyzes your data lake usage patterns, query workloads, and data relationships to automatically design optimal star or snowflake schemas. It identifies dimension and fact tables, creates appropriate indexes, and optimizes for your specific analytics needs, achieving 10x faster query performance.

Can I keep my data lake after migration?

Yes, many organizations maintain both. The data lake stores raw, unstructured data for data science and ML workloads, while the warehouse provides structured, optimized data for BI and analytics. AI can set up automated pipelines to keep both synchronized.

How long does data lake to warehouse migration take?

With AI-powered automation, most migrations complete in 3-4 weeks including schema design, ETL development, data migration, and BI integration. Manual migrations typically take 4-6 months. Timeline depends on data volume, complexity, and number of BI tools to migrate.

What are the cost savings of migrating to a warehouse?

Organizations typically see 75% cost savings through reduced storage costs (structured data is more efficient), lower compute costs (optimized queries), and faster development (pre-built schemas). Migration costs are also 75% lower with AI automation: $100K-$200K vs $400K-$800K for manual migration.
