Oracle EBS to Oracle Cloud Fusion Migration: Complete Roadmap for Indian Enterprises in 2026
- By Virender Kumar, Head of Cloud & Database
- Published May 08, 2026
Oracle has extended Premier Support for Oracle E-Business Suite (EBS) 12.2 through at least 2037 — so a shrinking support window is not the reason to move. Many Indian enterprises are migrating to Oracle Fusion Cloud ERP anyway, for real gains in AI, mobility, and real-time analytics. This guide is the most practical Oracle EBS-to-Cloud migration roadmap available for Indian businesses.
Why Indian Enterprises Are Moving to Oracle Fusion Cloud Now
- GST and e-invoicing compliance — Oracle Fusion Cloud's India localisation is updated quarterly by Oracle; EBS requires manual patches
- No hardware cost — Oracle Cloud SaaS eliminates on-premise data centre expenses
- AI and ML built-in — Fusion Cloud includes Oracle AI for Finance (automated journal entries, anomaly detection, expense fraud detection)
- Mobile-first — Full functionality via Oracle Mobile app; EBS is browser-only with limited mobile support
- Continuous updates — Quarterly cloud updates include new features automatically; EBS upgrades require separate projects
The Migration Roadmap: 6 Phases
Phase 1: Discovery and Assessment (Weeks 1–4)
The most critical and most underestimated phase. Key deliverables:
- Module inventory — Document every EBS module in use (GL, AP, AR, FA, INV, PO, OM, HRMS, Payroll)
- Customisation catalogue — List every Oracle Forms customisation, RICEW object (Reports, Interfaces, Conversions, Extensions, Workflows), and custom database packages. This is typically 200–500+ objects for a mid-size company.
- Integration map — Document every system talking to EBS (CRM, WMS, banks, tax portals, EDI partners)
- Data volume assessment — Count open transactions, historical records, and archived data
- Fit-gap analysis — Map EBS functionality to Fusion Cloud standard features. In our experience, 70–80% of EBS customisations are replaced by standard Fusion features
Phase 2: Design and Configuration (Weeks 5–12)
Configure Oracle Fusion Cloud to match your business requirements:
- Chart of Accounts restructuring (Fusion uses a Segment structure — rethink your COA for better reporting)
- Legal Entity and Business Unit setup (maps to EBS Operating Units)
- India Localisation setup: GSTIN, TDS/TCS configuration, e-invoicing integration
- Approval workflows in BPM Worklist (replaces EBS AME)
- OTBI and Financial Reporting Studio report configuration
Phase 3: Data Migration (Weeks 8–16, parallel with Phase 2)
Data migration is the highest-risk activity. Strategy decisions:
| Data Type | Recommended Approach |
|---|---|
| Open Supplier Invoices | Migrate all open/unpaid invoices to Fusion AP |
| Open Customer AR | Migrate open balances; closed invoices — archive only |
| Fixed Assets | Full migration with depreciation history (use Oracle FBDI templates) |
| General Ledger History | Migrate last 2 years as journal summaries; archive older years |
| Inventory on Hand | Migrate at cutover with physical count verification |
| Purchase Orders | Open POs only — closed POs archive in EBS |
| Employee Master (HR) | Full migration if moving HCM module too |
Phase 4: Integration Development (Weeks 10–18)
Rebuild EBS integrations on Oracle Integration Cloud (OIC) or equivalent middleware. Modern Fusion Cloud integrations use REST APIs — far simpler than EBS's XML Gateway or flat file interfaces.
Priority integrations to rebuild first:
- Bank statement import (Oracle Cash Management)
- Payment file generation (NEFT/RTGS/SWIFT)
- GST return data export to GSTN
- E-invoicing integration (IRP/GSP)
- Legacy system interfaces (if EBS was the hub)
Phase 5: Testing (Weeks 16–22)
Three rounds of testing are essential:
- System Integration Testing (SIT) — test all configured processes end-to-end
- User Acceptance Testing (UAT) — business users validate against real scenarios using actual data
- Parallel Run — run EBS and Fusion simultaneously for one full accounting period (optional but strongly recommended for Finance)
Phase 6: Cutover and Go-Live (Weeks 22–24)
Execute the cutover plan:
- Freeze EBS transactions at period end (T-3 days)
- Extract final open balances from EBS
- Load opening balances into Fusion
- Validate totals match to the rupee
- Go live — Fusion becomes the system of record
- Keep EBS in read-only mode for 90 days post-cutover
Typical Timeline and Cost for Indian Mid-Market Companies
| Company Size | Modules | Timeline | Typical Investment |
|---|---|---|---|
| 50–200 users | Financials + Procurement | 4–5 months | ₹40–80 lakh |
| 200–500 users | Financials + SCM + HR | 6–9 months | ₹80 lakh–1.5 crore |
| 500+ users | Full Suite | 12–18 months | ₹1.5–4 crore |
