HexaRocket now supports PostgreSQL to Oracle - Data Migration and CDC for replication (August, 2025)

We are excited to announce another major expansion of HexaRocket’s universal migration ecosystem. A complete PostgreSQL to Oracle - Schema Migration, Data Migration and real-time CDC replication is now officially available.

This new capability enables organizations to migrate data, synchronize systems, and maintain continuous bi-directional replication between PostgreSQL and Oracle, all through a single unified platform. Whether you’re consolidating systems, modernizing apps, or supporting hybrid architectures, this release unlocks seamless interoperability between two of the world’s most widely used databases.

Why We Introduced PostgreSQL → Oracle Migration & CDC

Enterprises increasingly operate mixed PostgreSQL + Oracle environments due to modernization, acquisitions, cloud adoption, or departmental autonomy. But this creates challenges:

• Difficulty migrating PostgreSQL workloads back to Oracle when required
• Lack of automated schema + data transformation pipelines
• No reliable CDC tools for PostgreSQL → Oracle
• Heavy custom scripting for bidirectional sync
• High operational risk when maintaining multiple solutions for replicating between Oracle and PostgreSQL.

Customers repeatedly asked -

“We have PostgreSQL workloads but still rely on Oracle for reporting, compliance, or legacy applications - can we sync them continuously?”

“If we move to PostgreSQL but need to revert, is there a rollback path?”

HexaRocket now delivers a fully automated, production-grade solution for these needs.

What This Release Provides

1. Automated PostgreSQL → Oracle - Schema Migration

• Intelligent mapping of PostgreSQL data types to Oracle equivalents
• Conversion of sequences, constraints, indexes, partitions
• Auto-handling of case-sensitivity, quoting, and naming rules
• Warnings and validation for incompatible objects
• Migration-ready Oracle schema generation at scale

2. High-Performance PostgreSQL → Oracle Bulk Data Migration

• Parallel extract and load for maximum throughput
• Buil-in data validation upon full load - validation per table
• Restart-safe migration workflow
• Large table splitting & batching
• Optimized network and commit strategies
• Designed for multi-terabyte workloads and production-grade reliability.

3. Real-Time Change Data Capture (CDC) from PostgreSQL WAL

• HexaRocket now provides a robust CDC pipeline, including -
• WAL-based extraction of inserts, updates, deletes
• Guaranteed ordering and transactional consistency
• Intelligent batching & checkpointing
• Near-zero-latency replication
• Change-level validation and tracking
• This ensures Oracle remains continuously synchronized with PostgreSQL.

4. High-Throughput Apply Engine for Oracle

• Parallel workers for fast apply
• Automatic conflict resolution
• Adaptive retry logic for transient failures
• Idempotent and safe apply with commit-by-commit consistency
• No dependency on GoldenGate or native tools
• HexaRocket brings its own lightweight, enterprise-grade Oracle apply engine.

5. Full Operational Control Through the HexaRocket UI

• Start / Pause / Resume CDC
• Control extract and apply pipelines independently
• Adjust parallel workers and resource allocations live
• Monitor replication lag, throughput, and retry events
• Table-level pipeline control and restarts
• The same intuitive experience used for Oracle → PostgreSQL CDC is now extended to PostgreSQL → Oracle.

Who This Release Is For

This addition is designed for -

• Companies running hybrid PostgreSQL + Oracle architectures
• Enterprises with modernization programs but requiring Oracle-compatible fallbacks
• Teams that need to keep Oracle in sync for reporting, BI, or legacy apps
• Organizations migrating datasets from PostgreSQL to Oracle Cloud (OCI)
• Enterprises needing rollback-safe or bidirectional replication workflows

Whether moving critical workloads across platforms or building cross-environment pipelines, this release ensures safe, reversible, and controlled data movement.

Strengthening HexaRocket’s Universal Migration Vision

With this release, HexaRocket now supports true bidirectional replication across PostgreSQL and Oracle -

• Oracle → PostgreSQL (Schema, Data, CDC)
• PostgreSQL → Oracle (Schema, Data, CDC)

Along with -

• SQL Server → PostgreSQL Migration & CDC
• Oracle → Oracle Migration & CDC
• PostgreSQL → PostgreSQL cross-environment replication (coming soon)
• And additional connectors underway

HexaRocket continues to unify schema migration, bulk data transfer, and CDC replication into one enterprise-class platform, removing the need for multiple tools, manual scripts, or vendor lock-in.
