Overcoming Technical Challenges in Oracle Database Migration to PostgreSQL

Key Highlights

  • OptiSol partnered with a leading enterprise to modernize its Oracle database infrastructure, automating the migration to PostgreSQL while ensuring data integrity and structural consistency.
  • By analyzing and optimizing query structures, the solution eliminated performance bottlenecks, enhancing processing speed and overall database efficiency.
  • Real-time synchronization enabled incremental data migration, reducing business disruptions and ensuring an uninterrupted transition with minimal manual intervention.
  • Integrated data encryption protocols safeguarded sensitive information, ensuring GDPR compliance and secure data transfer throughout the migration process.

Problem Statement

01

PL/SQL Complexity – Extensive interdependencies in Oracle’s PL/SQL functions, stored procedures, triggers, and constraints made migration error-prone, requiring meticulous handling to maintain data integrity.

02

Data Compatibility – Oracle’s specialized data types and custom structures posed challenges in mapping to PostgreSQL, while unoptimized queries and processes led to performance bottlenecks.

03

Large-Scale Migration – Moving high-volume data with minimal downtime was critical, along with ensuring secure data transfer and GDPR compliance for business continuity.

Solution Overview

01

OptiSol leveraged iBEAM - DbSyncX to automate the conversion of Oracle’s PL/SQL code, including triggers, procedures, functions, and packages, into PostgreSQL’s PL/pgSQL while preserving dependency and minimizing manual errors.

02

Our team replicated Oracle schema constraints, partitions, and complex data types into PostgreSQL without manual intervention, preserving data consistency and structural integrity.

03

We optimized query structures by analyzing Oracle’s existing queries and eliminating performance bottlenecks, improving processing speed and overall database efficiency.

04

A real-time synchronization mechanism was implemented for incremental data migration, reducing downtime and ensuring a smooth transition without business disruptions.

05

To maintain security and compliance, we integrated data encryption protocols throughout the migration process, protecting sensitive information and ensuring GDPR adherence.
