Approach

Understand what Oracle is actually doing before you convert it.

I do not start with blanket conversion. First, Oracle-specific logic and dependencies are made visible. Then the PostgreSQL/AWS target is validated on a representative flow, and only then is the migration broken into controlled delivery units.

Discuss your migration

Capture the Oracle estate and the code

Inventory objects, packages, procedures, functions, triggers, jobs, database links, grants and dependencies. Read source code and metadata together so object counts are not mistaken for migration effort.

Assessment

Test the hotspots on the real target

Define a PoC around the highest-risk components: PL/SQL replacement patterns, data model, extensions, performance, deployment and application behaviour against PostgreSQL or Aurora.

Proof of concept

Split delivery into testable waves

Structure schema and code changes, data movement, Flyway deployment, tests, cutover and rollback so every step can be accepted independently.

Migration delivery

Internal macOS working tool

Inventory, source code and findings in one working context.

The GCON-DB Migration Studio is my internal macOS working tool supporting analysis, migration and validation. I use it alongside established tools for inventory, file analysis and structured assessment of migration findings.

The screenshot is intentionally only a glimpse into my working process. The value lies in the engineering judgement that follows: what must be rewritten, decoupled, tested or simply documented?

Output of each phase

Fewer unresolved migration questions—not more slides.

Which Oracle components drive the largest change effort?
Which behaviours map cleanly and which require a different design?
Which assumptions need proof with real code or representative load?
Which migration units can be implemented and tested independently?
What do deployment, reconciliation, cutover and rollback look like on the target?

Want to put your Oracle estate into context?

For an initial discussion, Oracle version, rough scale, PL/SQL footprint and intended target are enough.
