Oracle E-Business Suite has run Finance, Supply Chain, Procurement and HR for thousands of companies over the last two decades. Most of those companies customized it heavily along the way. That work kept the business running. It also became the heaviest thing to carry into the cloud.
Moving to Oracle Fusion Cloud is the moment to decide what deserves to come along. Companies that use AI to make that call, and to take on the repetitive parts of the move, can arrive with a cleaner system that is ready for the AI features Oracle ships every quarter.
Key Takeaways
- Oracle has extended Premier Support for EBS 12.2 to at least 2037, so there is time to plan the move properly.
- The biggest risk in any ERP migration is carrying years of customizations and messy data into the new system.
- AI can speed up discovery, custom code review, integration mapping and testing, which are the most manual parts of the job.
- Fusion is updated four times a year, so testing and support after go-live matter as much as the migration itself.
What Is an Oracle EBS to Fusion Cloud Migration?
An Oracle EBS to Fusion Cloud migration is the move from Oracle E-Business Suite, which most companies run on their own servers, to Oracle Fusion Cloud Applications, a software-as-a-service suite that Oracle hosts and updates. It covers business processes, data, customizations, integrations, reports and the people who use the system every day.
Do You Have to Leave EBS Right Now?
You do not have to rush. In March 2026, Oracle extended Premier Support for EBS 12.2 to at least 2037. This was the ninth yearly extension since 2018, and Oracle's own EBS roadmap confirms the commitment.
That long runway changes the conversation. With no deadline forcing a quick lift-and-shift, the case for moving comes down to value. Fusion is where Oracle is putting its new AI work. Its 26C quarterly release alone listed 139 AI-flagged features, and 109 of them were agent features. Oracle also includes AI Agent Studio, its tool for building and running agents, with Fusion subscriptions at no additional cost.
The planning window is still shorter than it looks. Large, full-suite programs often take 18 to 36 months, while smaller, focused moves can take 12 to 18 months. Companies that want to be on Fusion well before 2037 need to start the groundwork now.
Why Do Traditional ERP Migrations Carry the Past Forward?
The SAP world offers a useful warning for Oracle customers. ISG surveyed 200 senior leaders in early 2026 and found that nearly 60% of SAP migration projects ran late or over budget. Almost half did little or no re-engineering and simply kept their old processes and data. More than half said they had customized their old ERP so heavily that standardizing now felt risky.
ISG also found that delays come mostly from weak governance. Decision rights, acceptance criteria and ownership across vendors often stay unclear, and fragmented accountability leads to scope creep.
Its research also shows that fragmented processes, heavy customization and old data structures limit which AI use cases a company can deploy after go-live. Oracle customers face the same trap.
EBS-to-Fusion programs run into five familiar hurdles:
- Years of customizations. Custom reports, interfaces, conversions, extensions and workflows (often called RICEW objects) pile up over a decade or more.
- Legacy data. Records need cleansing, mapping and reconciliation before they can move.
- Integrations and reports. Hundreds of interfaces have to be rebuilt for the cloud.
- Testing. Every critical business process needs to be checked before go-live, and again after every quarterly update.
- Adoption. People need to learn new screens and new ways of working.
Done by hand, each of these takes months of repetitive analysis, which is the kind of work AI handles well. Governance is the exception. Clear owners and decision rights have to come from people, with AI supplying the evidence.
How Does PrimeSoft Bring AI Into Each Stage of the Migration?
PrimeSoft has delivered enterprise technology programs for more than 20 years and offers Oracle ERP advisory, implementation and managed services across Finance, SCM, HCM and Oracle Cloud Infrastructure. Its approach puts AI to work at each stage of the move. PrimeSoft's Oracle consultants guide every decision, with Oracle Unified Method (OUM) governance throughout.
1. AI-Assisted Discovery and Readiness
AI tools analyze the current EBS setup, including configurations, customizations, integrations and processes. The team then builds a migration plan based on evidence from your own system.
2. Intelligent Customization Rationalization
AI reviews each legacy RICEW object and checks whether Fusion already offers a standard feature that does the same job. PrimeSoft's consultants then work with your teams to decide whether to retire it, redesign it or keep it as a governed extension. Every customization built has to be regression tested after every quarterly update, so each one you retire lowers the cost of running Fusion.
3. AI-Assisted Data Migration
AI helps profile legacy data, find duplicates and gaps, and suggest how old fields map to Fusion. Reconciliation checks then confirm that balances and records match after the move.
4. Intelligent Integration Modernization
AI speeds up the analysis of existing EBS interfaces and maps them to Oracle Integration Cloud (OIC) and REST APIs. This gives teams a chance to replace older point-to-point connections with a cleaner integration layer.
5. AI-Driven Testing With QualNetics.AI
QualNetics.AI is PrimeSoft's AI quality engineering platform. It generates test cases from your requirements and code, runs regression tests across critical business processes, and repairs its own automation when screens change. PrimeSoft reports up to 60% faster QA cycles and up to 40% fewer production defects with the platform.
Its value grows after go-live. Oracle gives Fusion customers a two-week window between the test and production updates each quarter. Automated regression makes that window long enough to test properly, every quarter.
6. Knowledge That Stays With You
Decades of EBS know-how often live in the heads of a few long-serving people. The PrimeSoft Knowledgebase captures processes, customizations and design decisions from your EBS estate and makes them searchable, so that knowledge stays with the business after the move.
7. Agentic AI for Operations After Go-Live
Once Fusion is live, AI agents monitor transactions, flag exceptions and recommend corrective actions. A person reviews and approves the actions that matter. PrimeSoft builds these agents on its 7-Layer Agentic AI Framework, which records every automated decision in an audit trail and uses review gates to keep people in control. The agents work alongside PrimeSoft's 24x7 managed services, which cover L1 to L3 support, AI-assisted triage and quarterly update support.
What Changes When AI Supports the Migration?
The first change is in where people spend their time. Analysts spend less effort reading old code and building spreadsheets of interfaces, and more effort deciding how the business should run. Fewer customizations make the move lighter, and they make every future quarterly update easier to test.
The second change comes after go-live. A cleaner system with well-governed data is better placed to use the AI agents Oracle adds to Fusion each quarter. The migration becomes the starting point for that work.
PrimeSoft has done this before. For a national orthotic and prosthetic care provider that grew through acquisitions, it brought many acquired systems onto one modern Oracle ERP core with a single data-exchange backbone. The business now has centralized data that is ready for analytics and AI.
Frequently Asked Questions
- How long does an Oracle EBS to Fusion Cloud migration take? Large, full-suite programs commonly take 18 to 36 months. Smaller, focused moves can take 12 to 18 months.
- Should we move all our EBS customizations to Fusion? Most companies should not. Many customizations duplicate features that Fusion now provides as standard. Each one you keep adds testing work every quarter, so review each one before deciding to move it.
- Is Oracle EBS reaching end of life? EBS 12.2 is not at end of life. Oracle has committed Premier Support for it through at least 2037.
- How do Fusion quarterly updates affect testing? Oracle updates Fusion four times a year and gives customers about two weeks between the test and production updates. Automated regression testing makes that window manageable.
- Can AI agents run Fusion operations on their own? AI agents can monitor transactions, flag problems and recommend fixes. For actions that matter, a person should review and approve them, which keeps the business in control and leaves a clear audit trail.
