Why Enterprises Are Migrating from Oracle to PostgreSQL

Before selecting an Oracle to PostgreSQL conversion tool, organizations must understand the strategic and technical drivers behind database modernization:

1. Cost Optimization & License Elimination

PostgreSQL removes expensive Oracle licensing and support fees, reducing total cost of ownership (TCO) while maintaining enterprise-grade reliability.

2. Open-Source Flexibility & Extensibility

PostgreSQL supports custom data types, extensions, advanced indexing strategies, and extensible storage engines — making it ideal for modern applications, analytics, and microservices architectures.

3. Cloud-Native Compatibility

PostgreSQL integrates seamlessly with managed cloud services such as:

  • Amazon RDS & Aurora PostgreSQL

  • Azure Database for PostgreSQL

  • Google Cloud SQL for PostgreSQL

This ensures elasticity, high availability, and simplified infrastructure management.

However, Oracle to PostgreSQL migration is not a simple export-and-import operation. It involves:

  • Schema transformation and DDL conversion

  • PL/SQL to PL/pgSQL refactoring

  • Data type mapping and constraint translation

  • Dependency analysis

  • Performance re-engineering

  • Transactional integrity validation

Without a structured and automated Oracle to PostgreSQL conversion tool, risk and complexity increase exponentially.

DMAP Architecture & Oracle to PostgreSQL Migration Workflow

Phase 1: Discovery & Intelligent Assessment

A successful Oracle to PostgreSQL migration begins with deep system visibility.

DMAP performs object-level analysis of the Oracle environment, cataloging:

  • Tables, indexes, constraints, triggers

  • Views and materialized views

  • Stored procedures and functions

  • Packages and PL/SQL business logic

  • Embedded SQL within applications

  • Inter-object dependencies

Unlike heuristic-based scanners, DMAP provides:

  • Predictive complexity scoring

  • Migration feasibility analysis

  • Risk identification for incompatible constructs

  • Effort estimation models

This structured assessment significantly reduces migration uncertainty and improves planning accuracy.

Phase 2: Automated Schema & Code Conversion

Schema Transformation

DMAP converts Oracle schema objects into PostgreSQL-compatible structures, including:

  • Data type mapping (NUMBER → NUMERIC, VARCHAR2 → VARCHAR, etc.)

  • Constraint translation

  • Index conversion

  • Sequence handling

  • Dependency resolution

PL/SQL to PL/pgSQL Refactoring

One of the most complex aspects of Oracle migration is procedural logic conversion.

DMAP automatically transforms:

  • Stored procedures

  • Functions

  • Packages

  • Triggers

Complex constructs such as dynamic SQL, cursors, exception handling, and autonomous transactions are identified and flagged for guided refactoring, ensuring production-grade code quality.

Data Migration & Synchronization

DMAP orchestrates parallelized, high-throughput data migration with:

  • Bulk loading optimization

  • Incremental data capture

  • Consistency validation

  • Transaction-safe cutover strategies

This reduces downtime and ensures production readiness.

Phase 3: Validation, Automation & Performance Engineering

DMAP extends beyond conversion by embedding automated validation frameworks:

Data Integrity Validation

  • Row count reconciliation

  • Checksum verification

  • Constraint validation

Performance Benchmarking

  • Query plan comparison

  • Index optimization

  • PostgreSQL configuration tuning

Cloud Environment Optimization

  • HA configuration alignment

  • Security and compliance policy mapping

  • Resource optimization for AWS, Azure, or GCP

This end-to-end automation transforms Oracle to PostgreSQL migration into a repeatable modernization process.
