Oracle EBS to Dynamics 365 Data Migration
Moving from Oracle EBS to D365 Finance & Operations? Settle automates the mapping between Oracle's TCA model and D365's customer entity framework — including multi-org translation, flexfield conversion, and chart of accounts restructuring.

Enterprise migrations routinely run months behind schedule. Yours doesn't have to.
This guide is for VPs of IT, data architects, and migration leads at companies moving data from Oracle EBS to Microsoft Dynamics 365 — whether you're scoping, planning, or mid-program.
Oracle EBS and Microsoft Dynamics 365 use fundamentally different data architectures. Settle bridges this structural gap automatically — handling schema profiling, field mapping, data transformation, and validation that typically consumes months of manual effort.

How Settle automates your Oracle EBS to Microsoft Dynamics 365 migration
Settle auto-profiles Oracle's TCA hierarchy and maps it to D365's customer account model — denormalizing party, account, site, and site use records into clean customer entities with address preservation.
Oracle multi-org structures are analyzed and mapped to D365 legal entities — with cross-org customer and vendor relationships flagged for intercompany configuration.
DFF segments are profiled from the Oracle repository and mapped to specific D365 fields — each context-value combination gets its own mapping rule with data value transformation.
Settle validates open transaction balances after migration — ensuring AP, AR, and inventory sub-ledger totals match the GL in D365 before cutover.

Common challenges migrating from Oracle EBS to Microsoft Dynamics 365
Oracle TCA to D365 customer model
Oracle EBS's TCA model stores party, customer account, site, and site use data across HZ_PARTIES, HZ_CUST_ACCOUNTS, HZ_PARTY_SITES, and HZ_CUST_SITE_USES. D365 uses a simpler customer account model with addresses stored on the customer or through the global address book. Denormalizing Oracle's multi-level TCA hierarchy into D365's flatter structure requires business rules for address consolidation and site purpose mapping.

Oracle EBS uses operating units, sets of books, and legal entities with complex multi-org access control. D365 uses legal entities as the primary organizational boundary. Determining which Oracle org structures map to D365 legal entities vs. business units vs. operating units requires deep analysis of how the Oracle orgs are actually used.
Explore related migrations →Descriptive and Key Flexfield conversion
Oracle EBS DFFs use context-sensitive segment columns (ATTRIBUTE1-15) whose meaning varies by context value. D365 doesn't have an equivalent mechanism — each DFF segment must become a specific field on the corresponding D365 entity or a custom field. Key Flexfields like the accounting flexfield must map to D365's chart of accounts and financial dimensions.
Explore related migrations →Open transaction migration and GL reconciliation
Migrating open AP invoices, AR invoices, and purchase orders requires translating Oracle's document structures (AP_INVOICES_ALL, RA_CUSTOMER_TRX_ALL, PO_HEADERS_ALL) to D365 equivalents with proper status mapping, aging preservation, and GL account translation. Post-migration, sub-ledger balances must reconcile to the GL in both systems.

The cost of manual Oracle EBS to Microsoft Dynamics 365 migration
Oracle EBS to Dynamics 365 migrations are increasingly common as companies look for alternatives to Oracle's own Cloud ERP upgrade path. Some companies prefer Microsoft's ecosystem and licensing model over Oracle's. Others find D365's Power Platform extensibility more accessible than Oracle Cloud's limited customization. PE-backed companies often choose D365 for its lower implementation cost relative to Oracle Cloud, especially when the company already runs Office 365 and Azure.
The technical complexity is substantial — both platforms are full-featured enterprise ERPs with deeply different architectures. Oracle EBS's Trading Community Architecture (TCA) for customer and party data must map to D365's simpler customer account model. Oracle's multi-org structure (operating units, sets of books, legal entities) translates to D365's legal entity model differently than it would to Oracle Cloud. Flexfields, lookup values, and Oracle's extensive PL/SQL customizations all require analysis and translation.
These migrations are typically managed by large consulting firms over 12–18 months. The data conversion workstream — profiling custom tables, mapping TCA, translating flexfields, validating open transactions — is one of the most labor-intensive parts of the program.
Consulting-led delivery for migrations in this class typically runs $1.5M+. Settle prices it fixed and scoped — read the full cost breakdown.
