You will get an Oracle to PostgreSQL database migration assessment and plan
Project details
I help companies plan and execute complex Oracle to PostgreSQL database migrations, including migrations to Amazon RDS for PostgreSQL and Amazon Aurora PostgreSQL.
My approach is based on real-world enterprise database migration experience with multi-terabyte, highly transactional systems and production workloads.
Depending on the selected package, I can help with:
• Oracle database and schema assessment
• Migration complexity and risk analysis
• AWS Schema Conversion Tool (AWS SCT) assessment and schema conversion
• AWS Database Migration Service (AWS DMS) architecture and configuration
• Full Load and Change Data Capture (CDC) strategy
• Oracle-specific SQL, PL/SQL, data type, and feature compatibility analysis
• Performance and infrastructure planning
• Data validation, testing, cutover, and rollback planning
You will receive practical recommendations based on your actual database environment—not a generic migration checklist.
Before starting, I review your Oracle version, database size, architecture, workload, target PostgreSQL platform, downtime requirements, and migration goals.

About Oleksandr
Database Migration & Performance Engineer | Oracle, PostgreSQL, MSSQL
Kiev, Ukraine - 10:25 pm local time
I have more than 15 years of experience working with Oracle, PostgreSQL, and Microsoft SQL Server databases. My main specialization is database migration and performance optimization.
I help companies migrate large and complex databases, minimize downtime, troubleshoot migration issues, and improve database performance.
I understand the complete end-to-end database migration process — not just data transfer.
I can design a complete migration plan covering assessment, architecture, schema conversion, test migrations, infrastructure sizing, load and performance testing, production migration, data validation, cutover, and post-migration optimization.
Database Migration
• Oracle → PostgreSQL
• Microsoft SQL Server (MSSQL) → PostgreSQL
• Oracle → Oracle and cloud migrations
• On-premises → AWS and OCI
• Migration assessment and risk analysis
• Migration strategy and architecture design
• Schema and database code conversion
• Test migrations and migration rehearsals
• Full Load and CDC migration strategies
• Large databases and high-volume tables
• LOB data and partitioned tables
• Cutover planning and production migration
• Post-migration stabilization and optimization
Migration Tools & Technologies
• AWS Database Migration Service (AWS DMS)
• AWS Schema Conversion Tool (AWS SCT)
• Apache JMeter for load and performance testing
• Oracle Data Pump and RMAN
• AWS RDS
• Amazon Aurora PostgreSQL
• Oracle Cloud Infrastructure (OCI)
Testing, Validation & Production Readiness
A successful database migration is not complete until the new system has been tested and validated.
I can build a migration testing and validation plan that includes:
• Load and performance testing with Apache JMeter
• Infrastructure sizing based on real application workload
• Performance comparison before and after migration
• Data validation and row-count checks
• Data integrity and consistency checks
• Query and execution plan analysis
• QA testing support
• Production readiness checks
• Migration rehearsal and cutover validation
Database Performance Optimization
• SQL and query optimization
• Index design and optimization
• Execution plan analysis
• Database bottleneck analysis
• PostgreSQL autovacuum and table bloat optimization
• Partitioning strategies for large tables
• Performance troubleshooting under high load
• Performance optimization before and after migration
My experience covers the entire migration lifecycle — from the first assessment and migration plan to schema conversion, test migrations, performance testing, production cutover, data validation, and post-migration optimization.
I also have experience presenting a real enterprise Oracle-to-PostgreSQL migration case to a European AWS audience, covering the complete migration journey, AWS SCT, AWS DMS, performance testing with Apache JMeter, infrastructure optimization, data validation, and lessons learned from a large production environment.
If you are planning a database migration or experiencing database performance problems, I can analyze your environment, identify the main risks and bottlenecks, and build a practical migration or optimization plan.
