Oracle E-Business Suite to OCI Cloud Migration
Move your Oracle E-Business Suite from on-premise or legacy hosting to Oracle Cloud Infrastructure. Reduce cost, improve performance, and future-proof your platform — with a managed migration from start to finish.
The case for moving EBS to Oracle Cloud Infrastructure
Lower infrastructure cost
Remove on-premise hardware and maintenance costs. OCI typically reduces infrastructure spend versus managed datacentre hosting.
Improved performance
OCI bare metal and optimised shapes deliver measurable performance improvements for EBS — often 30–50% faster batch processing.
Eliminate end-of-life risk
Remove ageing on-premise hardware from the equation. OCI is maintained and updated by Oracle, removing infrastructure lifecycle risk.
Oracle-native integration
Running EBS on OCI gives you native integration with Oracle Analytics, OAC, and other Oracle Cloud services.
Simplified patching
The OCI environment simplifies E-Business Suite patching cycles — with faster clone and patch times compared to on-premise infrastructure.
Business continuity
OCI provides enterprise-grade disaster recovery options, backup services, and availability SLAs that are hard to match on-premise.
How an OCI migration works with APPSolve
We manage the entire process — from initial assessment through to post-go-live hypercare. Every migration is different, but our approach is consistent.
Discovery & sizing
We assess your current infrastructure, database size, customisations, and integrations. We produce a migration plan with timelines, costs, and risk items clearly documented.
OCI environment build
We provision your OCI tenancy, configure networking and security zones, and build the target environment to Oracle best practice.
Migration execution
We migrate your E-Business Suite application and database using Oracle-recommended tooling, with test migrations run first to validate the process before cutover.
Testing & sign-off
We run a structured testing cycle — technical, functional, and integration — and work with your team to achieve formal sign-off before going live.
Hypercare & handover
We provide intensive post-go-live support for an agreed period, resolving issues quickly and ensuring your team is confident with the new environment.
What actually goes wrong on OCI migrations — and how we plan around it
A lift-and-shift is lower risk than a re-implementation, but it is not risk-free. These are the failure modes we see most often, and the specific step in our process that exists to catch each one.
Undocumented customisations break on the target environment
Mitigation: Full CEMLI inventory during discovery, with each item tested against the OCI shape before cutover — not discovered during go-live weekend.
Cutover downtime runs longer than the agreed window
Mitigation: At least one full test migration is run and timed before the production cutover, so the go-live window is based on evidence, not an estimate.
Third-party integrations lose connectivity after the move
Mitigation: Every inbound and outbound integration is catalogued and validated against the new network and security configuration ahead of cutover.
Performance regresses instead of improving
Mitigation: OCI shape sizing is based on your actual batch and concurrent-user profile, not a generic template, with performance testing built into sign-off.

Do we have to re-implement EBS when we move to OCI?
No. A lift-and-shift migration moves your existing E-Business Suite system as-is to OCI — preserving all your data, customisations, and configurations. It is not a re-implementation.
How long does a migration take?
Most migrations take between six and sixteen weeks depending on database size, complexity, and internal stakeholder availability. We will give you a realistic estimate during discovery.
What happens to our existing infrastructure?
We recommend keeping existing infrastructure in a decommissioned state for an agreed period after go-live — typically 30–60 days — before final decommission.
Can you migrate a heavily customised EBS?
Yes. We have migrated heavily customised E-Business Suite environments including bespoke interfaces, custom forms, and third-party integrations. Customisation inventory is part of our discovery phase.
How much cutover downtime should we expect?
Most cutovers run within a single weekend maintenance window, typically 12–36 hours depending on database size and the number of interfaces that need revalidation. We size the window based on a timed test migration, not an estimate, so the figure you plan around reflects your actual data volumes.
Does OCI migration change our Oracle support and licensing position?
No — OCI migration keeps you on standard Oracle support and your existing EBS licensing; you are moving the infrastructure layer, not the support relationship. If you are also weighing third-party support as a separate cost-reduction lever, see our comparison on the why-appsolve page.
Ready to plan your migration?
A free discovery call is the first step. We will give you an honest view of what is involved and whether OCI is right for your organisation.
