Migrating Oracle E-Business Suite (EBS) to Oracle Cloud Infrastructure (OCI) is a complex undertaking for organizations seeking to modernize their ERP systems by moving to the Cloud. Migrating Oracle EBS to the Cloud involves transferring data and business processes, customizations, and integrations to a new cloud-based environment. Successfully navigating this migration requires meticulous planning, careful execution, and a deep understanding of Oracle EBS and OCI. Let’s understand the steps involved in Oracle EBS migration to OCI, gaining insights and best practices to help you seamlessly transition to cloud infrastructure while minimizing disruptions.

Assess Your Environment

Assessing your Oracle EBS environment involves a comprehensive analysis of your existing setup. This includes understanding the modules and versions you’re using, the complexity of customizations and integrations, data volumes, and any specific dependencies. This assessment helps you know what you’re dealing with and what needs to be migrated, which is crucial for planning the migration effectively.

Plan the Migration

Planning Oracle EBS migration to OCI is a critical step that involves creating a detailed roadmap for the entire process. It includes defining clear objectives, timelines, and resource allocation. You’ll also need to identify potential risks and mitigation strategies. During this phase, you’ll decide which data and components to migrate, considering factors like data relevancy and business continuity requirements.

Prepare the OCI Environment

Before migrating data, ensure your OCI environment is ready to receive it. This involves setting up virtual machines (VMs) or other compute instances, configuring the necessary storage solutions (e.g., block storage or object storage), and establishing network connectivity between your on-premises environment and OCI. You may also need to configure security policies and access controls to safeguard your data during and after migration.

Data Migration

Data migration is a pivotal step, and it begins with exporting data from your Oracle EBS. Depending on your specific requirements and the Oracle tools available, you might use tools like Oracle Data Pump, Oracle Data Migration Cloud Service, or custom scripts to extract the data. Once extracted, you may need to transform and cleanse the data to ensure it’s compatible with your target environment in OCI. This could include data format conversions, mapping changes, and data validation. Thorough testing and validation are crucial to ensure data integrity before migrating.

Application Migration

Application migration involves moving the core functionalities and configurations from your Oracle EBS to OCI. Depending on factors such as your EBS version and customizations, this step may require varying levels of effort. It often involves rewriting or reconfiguring customizations, extensions, and configurations to work seamlessly in the new OCI environment. Integration with Oracle Cloud services or reimplementing specific functionalities may also be necessary.

Customization Migration

Customization migration involves moving any custom code, extensions, or configurations in your Oracle EBS environment to OCI. This step may require adjustments and modifications to ensure these customizations are compatible with the new environment. The goal is to maintain the functionality and features essential to your business operations.

Integration Migration

This step involves the migration of integrations between your Oracle EBS and external systems to OCI. You’ll need to reconfigure or rewrite these integrations to work seamlessly with Oracle Cloud services or other applications in the OCI environment. This might involve leveraging Oracle’s integration tools and services to ensure that data flows smoothly between systems and that business processes remain uninterrupted.


Testing is a crucial phase of your project involving Oracle EBS migration to OCI. It involves thoroughly validating all aspects of the migration, including data, applications, customizations, and integrations. You should conduct functional testing to ensure that everything operates as expected, performance testing to assess system responsiveness under various loads, and security testing to identify and mitigate potential vulnerabilities. The goal is to uncover any issues or discrepancies and address them before proceeding to the final migration phase.

Backup and Disaster Recovery

Once you’ve migrated your data and applications to OCI, it’s crucial to establish robust backup and disaster recovery (DR) strategies. This involves configuring regular data backups and implementing disaster recovery mechanisms to protect against data loss and system downtime. OCI offers various backup and DR services, including automated backup solutions, storage replication, and site failover options. Ensuring data integrity and availability in case of unexpected incidents is paramount to the long-term success of your cloud deployment.

User Training and Documentation

After completing the technical aspects of the migration:

  1. Invest in user training and comprehensive documentation.
  2. Conduct training sessions to familiarize your users and IT staff with the new OCI environment and any workflow changes.
  3. Create user-friendly documentation that outlines procedures, best practices, and troubleshooting guidelines.

Clear communication and proper training help minimize disruptions and empower your team to make the most of the new environment.

Go Live

The “Go Live” phase is when you transition from your old Oracle EBS environment to the new OCI environment. This step requires careful planning to minimize business disruptions. During scheduled downtime, you’ll execute the migration, apply any final data synchronizations, and verify that everything is operational in the OCI environment. After successful verification, you can officially switch over to the new environment. It’s essential to have a rollback plan in case of unexpected issues during this critical phase.

Monitoring and Optimization

After the migration, continuous monitoring, and optimization of your OCI environment are essential. This step involves tracking system performance, resource utilization, and security on an ongoing basis. Use OCI monitoring and management tools to identify and address any issues that may arise proactively. Optimization efforts include adjusting resource allocations, implementing cost-saving measures, and applying security patches and updates. The goal is to ensure the long-term stability, efficiency, and security of your OCI deployment while aligning it with evolving business needs.

Decommission Old Environment

Decommissioning your old Oracle EBS environment is the final step in the migration process. This step involves safely and permanently retiring your previous environment’s hardware, software, and infrastructure. Before decommissioning, it’s crucial to verify that all data and applications have been successfully migrated and that there are no dependencies on the old environment. Ensure that all data backups and archives are securely stored and retained according to your organization’s data retention policies. Once you’re confident that the new OCI environment is fully operational and meets your business needs, you can proceed with shutting down or repurposing the old environment. This step marks the completion of the migration project and the full transition to OCI.
