Why MedaxAI

Not just a tool. A team that has done this before.

We have been migrating enterprise Oracle environments to open-source databases since before PostgreSQL had declarative partitioning. That experience is what your project inherits.

20+ Years in the Trenches

Our lead engineers have been migrating Oracle databases since the Oracle 9i era. We have seen every edge case — LOBs, partitioned tables, RAC clusters, linked DB servers, custom type hierarchies. Nothing surprises us.

We Built the Tool We Use

DBMigrateAIPro is not a third-party product we resell — it is the engine our team built and uses on every engagement. We ship fixes the same day we hit an edge case on your data.

Zero Data Loss, Guaranteed

We do not cut over until every row is verified. Row-hash checksums at the partition level mean we catch any discrepancy before it ever reaches production. Your data integrity is non-negotiable.

AI-Accelerated, Human-Verified

Our AI transpiler converts PL/SQL automatically and our engineers review every converted object. You get the speed of automation with the confidence of expert sign-off on the result.

Fixed-Price Engagements

We scope your migration upfront and give you a fixed price. No hourly billing surprises. No scope creep excuses. We own the outcome.

Full Documentation Handover

Every engagement ends with a complete migration playbook — what was done, why decisions were made, how to operate the new PostgreSQL environment. Your team inherits knowledge, not just a running database.

Our Process

Five phases. No shortcuts.

Every Oracle migration engagement follows the same rigorous process — built from 20 years of hard lessons on real enterprise databases.

01

Discovery & Assessment

1–2 weeks

We connect to your Oracle environment and produce a full migration assessment report — schema complexity, PL/SQL inventory, data volumes, dependency map, risk matrix, and a realistic timeline.

  • Schema & object inventory
  • PL/SQL complexity scoring
  • Data volume & growth analysis
  • Dependency & FK graph
  • Risk matrix & mitigation plan
02

Schema Translation

1–3 weeks

Every table, index, constraint, view, trigger, stored procedure, and package is translated to PostgreSQL. PL/SQL is auto-converted using our AI transpiler and hand-reviewed by our engineers.

  • DDL conversion — tables, indexes, constraints
  • PL/SQL → PL/pgSQL transpilation
  • Package decomposition & refactor
  • Sequence → IDENTITY / serial rewrite
  • Oracle-specific type mapping
03

Data Migration & Validation

1–4 weeks

Parallel bulk load with row-count and row-hash checksum validation. Every partition verified. Mismatches caught and resolved before cutover is even discussed.

  • Parallel bulk load (up to 16 workers)
  • Row-count validation per table
  • Row-hash checksum per partition
  • LOB & CLOB handling
  • Incremental sync before cutover
04

Zero-Downtime Cutover

1–4 hours

CDC-based live replication keeps PostgreSQL in sync with Oracle during the cutover window. When the switch happens, lag is under one second. You choose the window — we execute.

  • LogMiner / GoldenGate CDC sync
  • Sub-second lag at cutover
  • Automated rollback plan ready
  • Application connection switch
  • Post-cutover smoke test runbook
05

Handover & Support

30 days

We do not disappear after go-live. Our team provides 30 days of post-migration monitoring, query performance tuning, and developer enablement so your team is self-sufficient.

  • 30-day post-migration support
  • Query performance baseline & tuning
  • Developer enablement sessions
  • Runbook & playbook documentation
  • Optional ongoing managed DBA
FAQ

Common questions

How long does an Oracle to PostgreSQL migration take?

Typically 6–16 weeks end-to-end depending on schema complexity, data volumes, and PL/SQL inventory. Our assessment phase produces a precise timeline for your specific environment — not a generic estimate.

Can you migrate while our Oracle system is still in production?

Yes. Our CDC-based approach keeps PostgreSQL in continuous sync with Oracle throughout the engagement. Your Oracle system stays online until the moment you choose to switch. The cutover window is typically under 4 hours.

What happens to our PL/SQL stored procedures and packages?

We inventory every object, auto-convert with our AI transpiler, then hand-review every converted package and procedure. Complex logic — autonomous transactions, DBMS_SCHEDULER, UTL_FILE — is handled by our engineers directly.

Do you handle Oracle-specific features like partitioning and RAC?

Yes. Partitioned tables are mapped to PostgreSQL declarative partitioning, RAC is removed (PostgreSQL uses a different HA model), and we re-architect for the target correctly — not just port syntax.

What is your pricing model?

Fixed-price per engagement, scoped after the assessment phase. We do not bill hourly. You know your total cost before we begin data migration. Contact us for a scoping call and free preliminary estimate.

Can you migrate in stages — some schemas first, then the rest?

Absolutely. Phased migration is often the right approach for large Oracle estates. We design the phase boundaries, manage cross-schema dependencies, and keep data in sync across phases.
