Oracle to AlloyDB Migration Services
Move Oracle databases, application logic, and connected workloads to AlloyDB for PostgreSQL through a structured migration designed to protect data integrity and business continuity.
Migration Services
Move Oracle databases, application logic, and connected workloads to AlloyDB for PostgreSQL through a structured migration designed to protect data integrity and business continuity.
Why AlloyDB?
Modernize suitable Oracle applications using a PostgreSQL-compatible database and widely adopted PostgreSQL tools and extensions.
Reduce infrastructure, patching, backup, recovery, and high-availability management through a fully managed database service.
Support demanding transactional and hybrid transactional and analytical workloads using AlloyDB's cloud-native architecture.
Use AlloyDB AI, vector search, and Vertex AI integrations to build intelligent applications closer to operational data.
How We Migrate
Review Oracle versions, schemas, data volumes, PL/SQL, packages, applications, integrations, security, availability, and workload dependencies.
Define the AlloyDB architecture, migration waves, networking, security model, conversion approach, replication strategy, and validation plan.
Convert Oracle schemas, tables, and code objects to PostgreSQL syntax and migrate data to AlloyDB using the selected migration approach. Google Cloud Database Migration Service supports heterogeneous Oracle-to-AlloyDB migrations through conversion workspaces and managed migration jobs.
Compare source and target data, database logic, application behavior, transactions, permissions, integrations, and workload performance.
Complete final synchronization, promote the AlloyDB destination, transition applications, and optimize queries, indexes, capacity, backups, and monitoring.
Why Codimite?
Codimite combines Google Cloud expertise, database engineering, application modernization, and structured validation to support the complete migration journey.
Start Your MigrationGoogle Cloud Expertise. We build the target environment using AlloyDB and the wider Google Cloud application, data, and AI ecosystem.
Application-Led Planning. We migrate database objects together with the applications, integrations, jobs, and services that depend on them.
Structured Validation. We verify data, transactions, database logic, application behavior, security, and performance before production cutover.
Phased Migration. We reduce disruption through pilot workloads, ongoing replication, controlled cutover, and rollback planning.
Platform Comparison
Both platforms support enterprise database workloads, but AlloyDB provides a managed, PostgreSQL-compatible foundation with closer integration across Google Cloud.
| Area | Oracle Database | AlloyDB for PostgreSQL |
|---|---|---|
| Platform model | Proprietary enterprise relational database | ✓ Fully managed, PostgreSQL-compatible cloud database |
| Database engine | Oracle Database engine | ✓ Google-built PostgreSQL-compatible engine |
| Infrastructure | Deployment and operational responsibility depend on the selected Oracle environment | ✓ Underlying infrastructure, maintenance, and resource management handled by Google |
| Scaling | Depends on Oracle deployment, infrastructure, licensing, and architecture | ✓ Cloud-native compute and storage architecture with read-pool scaling options |
| Database language | Oracle SQL and PL/SQL | ✓ PostgreSQL SQL and PL/pgSQL-compatible development model |
| Licensing | Proprietary licensing and support agreements | ✓ Usage-based managed-service pricing without Oracle database licensing |
| Schema and code | Oracle data types, packages, procedures, triggers, and functions | ✓ PostgreSQL-compatible schemas, procedures, functions, extensions, and tools |
| High availability | Depends on the selected Oracle architecture and configuration | ✓ Built-in high availability with redundant nodes and automatic failover |
| Backup and recovery | Configuration and responsibility vary by deployment | ✓ Automated backups, continuous recovery, and point-in-time recovery capabilities |
| Analytics | Supports Oracle analytical and database capabilities | ✓ Columnar engine supports analytical queries alongside operational workloads |
| AI and vector capabilities | Depends on Oracle products, features, and integrations | ✓ AlloyDB AI, vector search, model invocation, and Vertex AI integration |
| Security | Oracle users, roles, privileges, encryption, and deployment controls | ✓ Google Cloud IAM integration, encryption, private connectivity, audit capabilities, and PostgreSQL permissions |
| Operations | Administration varies by self-managed or managed deployment | ✓ Infrastructure maintenance, patches, backups, and availability managed by Google |
| Cloud ecosystem | Closely connected to Oracle products and supported integrations | ✓ Closely integrated with Google Cloud applications, analytics, networking, and AI services |
FAQs
We can migrate schemas, tables, indexes, sequences, historical data, PL/SQL, packages, procedures, triggers, functions, applications, jobs, integrations, and access controls.
No. AlloyDB is PostgreSQL-compatible, so Oracle-specific schemas, data types, PL/SQL, packages, and application behavior must be converted and tested.
Google Cloud Database Migration Service provides conversion workspaces that help convert Oracle schemas and code objects to PostgreSQL syntax. Complex or unsupported objects may still require manual refactoring.
Database Migration Service can create and manage migration jobs that move data from Oracle to AlloyDB, monitor migration progress, and support destination promotion after synchronization.
Google Cloud supports continuous heterogeneous migration scenarios from Oracle to AlloyDB, subject to supported source configurations and migration requirements.
Packages and procedures are assessed and converted to PostgreSQL-compatible code where possible. Complex logic may be refactored into PL/pgSQL, application services, or another suitable Google Cloud component.
Most applications require some updates because drivers, SQL syntax, data types, stored logic, transaction behavior, and database-specific features can differ.
Database Migration Service supports multiple Oracle source types, including supported Oracle RAC and self-managed environments. Compatibility must be confirmed during assessment.
We compare row counts, business totals, database objects, transaction behavior, application results, permissions, integrations, and workload performance.
Yes. A temporary coexistence period can support ongoing replication, application testing, reconciliation, and controlled cutover.
Not necessarily. Cost depends on current Oracle licensing, infrastructure, support, workload requirements, migration effort, and the selected AlloyDB configuration.
Codimite assesses whether the feature should be converted, redesigned, moved into the application layer, replaced with another Google Cloud service, or temporarily retained.
Assess your Oracle environment and build a practical roadmap for schema conversion, data migration, application updates, validation, and production cutover.
