# How PostgreSQL on Azure helps modernize legacy databases

**[Microsoft Azure](https://daily.dev/sources/azure)** · 8 min read · 1 upvotes · 0 comments

## Summary

Microsoft outlines how Azure Database for PostgreSQL and the new Azure HorizonDB service help enterprises migrate away from Oracle and other legacy on-premises databases. Key highlights include an AI-assisted Oracle-to-PostgreSQL migration tool (powered by GitHub Copilot, available as a VS Code extension preview) that automates schema conversion, application code refactoring, and validation. A case study from Apollo Hospitals shows 60% cost reduction, 3x performance improvement, 99.95% uptime, and 40% faster deployments after migrating. Azure HorizonDB, currently in private preview, supports up to 3,072 vCores, 128 TB auto-scaling storage, sub-millisecond multi-zone commit latencies, and built-in AI/DiskANN capabilities for extreme-scale workloads.
