Introduction
Migrating Oracle E-Business Suite workloads to Oracle Cloud has become a major strategy for organizations looking to modernize infrastructure without immediately replacing their ERP applications. One of the most common migration approaches is the Lift and Shift Oracle E-Business Suite to Oracle Cloud Infrastructure strategy.
In real-world projects, many enterprises want to move away from aging on-premises data centers because of hardware refresh costs, maintenance complexity, disaster recovery limitations, and scalability challenges. However, replacing Oracle E-Business Suite completely is often expensive and time-consuming. This is where Oracle Cloud Infrastructure (OCI) becomes highly valuable.
A lift-and-shift migration allows organizations to move their existing Oracle E-Business Suite environments to OCI with minimal architectural changes. Businesses can retain their existing application configurations, customizations, integrations, and database structures while benefiting from OCI scalability, security, and performance improvements.
This article explains the complete lift-and-shift approach for Oracle E-Business Suite to OCI based on practical implementation experience using OCI 2026 architecture recommendations.
What is Lift and Shift Oracle E-Business Suite to OCI?
Lift and Shift is a migration strategy where an existing Oracle E-Business Suite (EBS) environment is moved from on-premises infrastructure to OCI without redesigning the application architecture.
The core objective is:
- Preserve the existing EBS application
- Move workloads to OCI compute infrastructure
- Maintain business continuity
- Reduce data center dependency
- Improve scalability and disaster recovery
In most projects, the following components are migrated:
| Component | Migration Scope |
|---|---|
| Oracle Database | Moved to OCI DB Systems or Exadata |
| Application Tier | Moved to OCI Compute Instances |
| Shared File Systems | Migrated to OCI File Storage |
| Load Balancers | Replaced using OCI Load Balancer |
| Backup Systems | Replaced using OCI Object Storage |
| DR Environment | Built using OCI regions |
This migration model is widely used by enterprises running:
- Oracle EBS R12.1.3
- Oracle EBS R12.2.x
- Highly customized EBS implementations
- Legacy ERP integrations
Why Organizations Move Oracle EBS to OCI
Organizations typically adopt OCI migration for the following reasons:
Data Center Exit Strategy
Many organizations want to eliminate physical data centers because of:
- Server maintenance costs
- Power and cooling expenses
- Hardware lifecycle management
- Capacity limitations
OCI removes infrastructure ownership responsibilities.
Improved Disaster Recovery
Traditional DR environments are expensive to maintain.
OCI provides:
- Cross-region replication
- Backup automation
- Faster recovery
- Reduced DR infrastructure costs
Better Performance
OCI offers optimized infrastructure for Oracle workloads including:
- High IOPS block volumes
- RDMA networking
- Exadata support
- Autoscaling compute options
Oracle EBS databases usually show performance improvements after migration.
Faster Infrastructure Provisioning
Provisioning new EBS environments on-premises may take weeks.
OCI enables:
- Rapid cloning
- Automated provisioning
- Infrastructure as Code
- Faster project timelines
Real-World Migration Use Cases
Scenario 1 – Manufacturing Company Data Center Exit
A manufacturing organization running Oracle EBS R12.2 on-premises migrated:
- Production
- UAT
- DEV
- DR environments
to OCI.
Key benefits achieved:
- 40% reduction in infrastructure cost
- Faster cloning for testing
- Centralized backup management
- Reduced DR maintenance effort
Scenario 2 – Retail Enterprise Seasonal Scalability
A retail company experienced performance issues during festive sales.
After migrating to OCI:
- Additional compute resources were provisioned dynamically
- Storage expanded online
- Load balancing improved concurrent user performance
Scenario 3 – Global Enterprise DR Modernization
A global enterprise implemented OCI cross-region disaster recovery.
Benefits included:
- Automated backups
- Standby database replication
- Reduced DR failover time
- Improved compliance readiness
OCI Architecture for Oracle E-Business Suite
A typical OCI architecture for Oracle EBS includes:
| OCI Component | Purpose |
|---|---|
| Virtual Cloud Network (VCN) | Network isolation |
| Compute Instances | Application tier hosting |

Step-by-Step Lift and Shift Migration to OCI
Step 1 – Create OCI Networking
Navigation:
Console → Networking → Virtual Cloud Networks
Create:

- Security lists
Example:
| Setting | Value |
|---|---|
| VCN CIDR | 10.0.0.0/16 |
| App Subnet | 10.0.1.0/24 |
| DB Subnet | 10.0.2.0/24 |
Best practice:
- Keep database servers in private subnets
- Restrict SSH access
- Use Bastion services
Step 2 – Provision Compute Instances
Navigation:
Console → Compute → Instances
Deploy:
- Application tier servers
- Web tier servers
- Concurrent manager servers
Example configuration:
| Component | Shape |
|---|---|
| App Tier | VM.Standard.E5.Flex |

- Optimize routing
2. File System Synchronization Issues
Incorrect shared storage configuration can impact application services.
Solution:
- Validate mount points carefully
- Use OCI File Storage properly
3. DNS and Hostname Problems
Application services may fail if hostname mappings are incorrect.
Solution:
- Validate /etc/hosts
- Configure DNS properly
4. EBS Customization Compatibility
Custom scripts may fail after migration.
Solution:
- Validate all customizations
- Recompile invalid objects
- Test integrations thoroughly
5. Downtime Management
Large databases increase migration downtime.
Solution:
- Use Oracle Data Guard
- Use incremental backups
- Plan phased cutover
Security Best Practices for OCI EBS Migration
Use Private Subnets
Keep:
- Database servers
- Internal application nodes
inside private networks.
Enable IAM Policies
Use least privilege access.
Example:
- Separate admin roles
- Separate backup roles
- Restricted SSH access
Encrypt Storage
Enable encryption for:
- Block volumes
- Object storage
- Database backups
Enable MFA
Multi-factor authentication should be mandatory for OCI administrators.
OCI Cost Optimization Tips
Use Flexible Compute Shapes
Flexible shapes reduce unused CPU allocation.
Schedule Non-Production Shutdowns
DEV and TEST systems can be stopped after business hours.
Use Object Storage Lifecycle Policies
Move old backups to archive storage automatically.
Monitor Resource Utilization
Remove unused resources regularly.
Best Practices for Successful Migration
Perform Detailed Discovery
Document:
- Customizations
- Interfaces
- Reports
- Batch jobs
- Third-party integrations
before migration begins.
Build a Separate DR Strategy
Production migration alone is not enough.
Design:
- Backup strategy
- DR failover testing
- Cross-region replication
Use Automation Wherever Possible
Automate:
- Provisioning
- Backups
- Monitoring
- Deployment
using Terraform and OCI automation services.
Conduct Multiple Mock Cutovers
At least 2–3 mock migrations should be performed before production cutover.
This helps identify:
- Downtime issues
- Performance bottlenecks
- Missing configurations
Maintain Proper Documentation
Maintain:
- Network diagrams
- Server inventories
- Migration procedures
- Rollback plans
This becomes critical during go-live.
