KEY HIGHLIGHTS
- OptiSol guided a global client in seamlessly migrating 10TB of data from Oracle to PostgreSQL using the iBEAM O2PIM tool and AI-driven automation.
- Incremental and batch transfers ensured zero data loss and minimal disruption to business operations.
- The client achieved approximately 80% savings on licensing and around 20% faster application performance after optimization.
- Comprehensive support included discovery, migration, post-migration optimization, and ongoing maintenance for a production-ready environment.
Why move to PostgreSQL?
- Lower licensing costs: PostgreSQL is open source, eliminating high Oracle license and maintenance fees and delivering immediate cost savings. This freed up budget for the client to reinvest in product development and infrastructure.
- Scalability for growth: PostgreSQL supports large datasets, partitioning, and horizontal scaling so the database can grow with demand. That flexibility also lets organizations adopt cloud or hybrid models later without major rework.
- Advanced feature set: Native JSON, full-text search, and flexible indexing enable modern application patterns and can outperform legacy Oracle setups in many workloads. These features simplify development for analytics, search, and semi-structured data use cases.
- Vendor independence: Moving to PostgreSQL reduces vendor lock-in and increases architectural freedom for future choices in cloud, tooling, and service providers. That independence lowers long-term risk and gives teams more control over total cost of ownership.
- Improved total cost of ownership and agility: Lower ongoing costs plus faster development iterations mean better TCO and quicker time to market. Reduced licensing and simpler operations make it easier to scale teams and features without ballooning expenses.
Our proven migration process
- Cataloging and mapping with iBEAM O2PIM: We inventory schema, indexes, views, and dependencies to build a complete, auditable migration blueprint. That thorough discovery reduces surprises and speeds up refactoring and validation.
- AI-driven code refactoring: Automated refactoring translates Oracle-specific constructs to PostgreSQL equivalents, reducing manual effort and errors. This accelerates development work and ensures functional parity across stored procedures and queries.
- Incremental transfer strategy: We use incremental, and batch data moves to keep the source live and minimize application downtime risk. By moving data in phases, we maintain transactional integrity while enabling continuous business operations.
- Comprehensive validation: Data integrity checks and parallel testing ensure zero data loss and functional parity before cutover. Multiple validation layers such as checksums, row counts, and application tests confirm accuracy and readiness.
- Post-migration hardening and support: Index tuning, query optimization, and configuration tweaks deliver production stability and improved performance. We also provide documentation and training so your team can operate the new environment confidently.
Business outcomes and support model
- Significant cost reduction: The client reduced licensing spend by about 80%, freeing budget for innovation and improving financial predictability. Lower recurring costs improved their ROI on the migration.
- Performance gains: Queries and application responsiveness improved by roughly 20% after schema tuning and optimizations. These gains translated into better user experience and lower resource consumption in production.
- Zero data loss and continuity: Full validation and incremental cutover preserved data integrity and day-to-day operations. The result was a seamless transition with stakeholder confidence and no business interruptions.
- Future-ready platform: The PostgreSQL environment is flexible for cloud migrations, analytics, and feature growth. It positions the client to adopt new architectures and scale without vendor constraints.
- End-to-end support: We offer consultation, migration execution, post-migration tuning, and long-term support to keep operations running smoothly. Our team remains available for ongoing optimization, troubleshooting, and enhancements.
FAQs:
Why are companies moving away from Oracle to open-source databases like PostgreSQL?
Organizations are moving away from Oracle due to high licensing costs, vendor lock-in, and limited cloud flexibility. PostgreSQL offers cost savings, open architecture, and modern ecosystem compatibility.
Can PostgreSQL run mission-critical applications?
Absolutely. With features like high availability, failover support, replication, and strong community-driven enhancements, PostgreSQL is production-ready for critical systems.
Is PostgreSQL capable of handling enterprise-scale workloads?
Yes, PostgreSQL is an advanced open-source relational database system trusted by global enterprises. It supports high-volume transactions, complex queries, and robust scalability across cloud and on-prem environments.
How secure is PostgreSQL for enterprise use?
PostgreSQL includes industry-standard security features such as SSL connections, role-based access control, row-level security, and extensibility for advanced encryption and auditing.
Can PostgreSQL be deployed in the cloud?
Yes, PostgreSQL is cloud-native and supported across major platforms including AWS (RDS, Aurora), Azure, GCP, and Kubernetes environments.
