Every migration includes automated reconciliation, and CDC-based live migrations keep production running during the move. Part of our [data engineering services](https://agilitytech.ai/solutions/data-engineering). Services ## Every type of data migration ### Cloud Data Migration Migrate data workloads to AWS, Azure, or GCP with zero-downtime strategies and full validation - AWS RDS / Redshift / S3 - Azure SQL / Synapse / Blob - GCP BigQuery / Cloud SQL - Automated validation & rollback ### Database Migration Migrate from legacy databases (Oracle, SQL Server, MySQL) to modern cloud-native solutions - Oracle → PostgreSQL - SQL Server → Azure SQL - MySQL → Aurora / Cloud SQL - Schema translation & testing ### Data Warehouse Migration Move your analytics workloads from on-premise warehouses to Snowflake, BigQuery, or Redshift - Teradata / Netezza migration - ETL pipeline replatforming - dbt model migration - Performance benchmarking ### Legacy System Modernisation Extract data from legacy systems, transform for modern architectures, and build new integration layers - ERP data extraction - Legacy mainframe integration - API layer development - Gradual cut-over strategy ### Real-Time Data Migration Live migrations with CDC (Change Data Capture) so production never goes down during the move - AWS DMS / Debezium - Kafka-based replication - Dual-write strategies - Lag monitoring & alerting ### Compliance-First Migration Migrate sensitive data (HIPAA, GDPR, PCI-DSS) with encryption, audit trails, and access controls intact - Data classification - Encryption in transit & at rest - Audit log migration - Compliance documentation Our guarantee ## Our migration guarantee ### Zero Data Loss Every migration includes automated reconciliation. We do not close a migration until every row is verified. ### Minimal Downtime CDC-based live migrations mean production keeps running. Most migrations achieve zero-downtime cut-over. ### Fixed-Price Scope We scope migrations with a fixed price and timeline. No surprise overruns after discovery. ### Compliance Maintained Your data stays compliant throughout. We handle HIPAA, GDPR, PCI-DSS data with appropriate controls. Case studies ## Migrations we've completed [See all case studies](https://agilitytech.ai/case-studies) ### FMCG Timeline: 8 weeks Legacy on-premise data warehouse holding 10TB of sales data: slow queries, high maintenance, no scalability. - Migrated to Snowflake with dbt-powered transformation layer. Zero downtime using dual-write during cut-over. - Query time cut by 90%. Infrastructure costs down 60%. Analytics team now self-serve. [Read the FMCG migration case study](https://agilitytech.ai/case-studies/fmcg-migration) ### Healthcare Timeline: 10 weeks Patient data siloed across 3 on-prem systems, making cross-system analysis impossible. - Unified data lake on AWS S3 with automated pipelines from all 3 systems, HIPAA-compliant architecture. - 40% faster patient risk reporting. Full HIPAA compliance maintained throughout. [Read the healthcare case study](https://agilitytech.ai/case-studies/healthcare-ai) ### Retail Timeline: 12 weeks Oracle ERP migration to cloud was stalled: custom schemas, 15 years of transactional data, no documentation. - Schema analysis, automated translation scripts, iterative migration with full data validation at every stage. - 100% data integrity verified. Oracle licences cancelled saving $400K/year.
