Oracle to PostgreSQL Migration via O2PIM
Eliminate Oracle licensing costs permanently. O2PIM — our Oracle to Postgres Intelligence Migration accelerator — automates schema conversion, PL/SQL translation, and data migration at enterprise scale, so you move faster with far less manual effort.
What We Cover
End-to-end migration, automated where possible
O2PIM handles the heavy conversion work. Our engineers step in for the nuanced gaps — complex business logic, performance edge cases, and application re-integration.
01
Oracle Schema Analysis
Automated inventory of all tables, indexes, constraints, sequences, and synonyms across your Oracle estate. O2PIM maps every object before a single line is converted.
02
O2PIM Automated Conversion
O2PIM converts schema DDL, data types, and object definitions automatically — achieving 90%+ automation rates that would take manual teams weeks to reach.
Automated03
PL/SQL → PL/pgSQL Translation
Stored procedures, triggers, functions, and packages converted from Oracle PL/SQL to PostgreSQL PL/pgSQL — with O2PIM handling syntax, cursor patterns, and exception handling.
04
Data Migration & Reconciliation
Full data transfer with row-count checks, hash validation, and reconciliation reports. AWS DMS and pg_dump pipelines configured for your data volume and downtime tolerance.
05
Application Re-pointing
JDBC, ODBC, and OCI connection strings updated to PostgreSQL drivers. Application-layer SQL dialect issues identified and resolved so your stack connects cleanly on day one.
06
Performance Tuning on Postgres
Query plan analysis, index strategy, autovacuum configuration, and connection pooling via pgBouncer — so your migrated system runs at or above Oracle baseline performance.
How O2PIM Works
Automation-first. Expert-closed.
The O2PIM methodology
O2PIM is an automated migration platform built specifically for Oracle-to-PostgreSQL migration. It ingests your Oracle DDL, PL/SQL source, and data dictionary, then produces a structured conversion output — schema DDL, translated procedure bodies, and a gap report — in a fraction of the time manual analysis would take.
O2PIM does not guess. Where a construct has a direct PostgreSQL equivalent, O2PIM converts it automatically. Where Oracle-specific behaviour has no direct equivalent — CONNECT BY hierarchical queries, ROWNUM patterns, Oracle hints — O2PIM flags the gap with context, and our engineers resolve each item with full understanding of the business logic.
The result is a migration that moves faster than purely manual approaches, but lands with the correctness that only expert review can guarantee. Most engagements see 90%+ of schema and procedure objects handled entirely by O2PIM, leaving engineers to focus on the genuinely complex 10% that automation cannot safely touch.
After conversion, the same pipeline drives data migration, reconciliation, and performance baseline testing — giving you a single, auditable migration record from first object inventory to production cutover.

Our Modernization Process
Four steps from Oracle to production PostgreSQL
Oracle Discovery & Inventory
O2PIM scans your Oracle instance — schemas, stored procedures, data volumes, dependencies, and licensing footprint — producing a complete migration inventory and effort estimate before any conversion begins.
O2PIM ScanO2PIM Automated Conversion
O2PIM converts all automatable objects: DDL, PL/SQL procedures, triggers, and sequences. Output includes a gap report that categorises every flagged construct by complexity and risk.
AutomatedExpert Gap Resolution & Testing
Engineers work through O2PIM's gap report — rewriting CONNECT BY hierarchies, resolving Oracle hints, validating business logic — followed by full regression testing and data reconciliation checks.
Human ExpertCutover & Post-Migration Support
Planned cutover with rollback readiness, application re-pointing, performance baseline confirmation, and a 30-day post-migration support window to catch any production edge cases.
Go-LiveTech & Tools
