Lift and Shift EBS to OCI

Share

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:

ComponentMigration Scope
Oracle DatabaseMoved to OCI DB Systems or Exadata
Application TierMoved to OCI Compute Instances
Shared File SystemsMigrated to OCI File Storage
Load BalancersReplaced using OCI Load Balancer
Backup SystemsReplaced using OCI Object Storage
DR EnvironmentBuilt 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

  • 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.
