Most enterprise migrations start 6+ 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 HR to Workday — whether you're scoping, planning, or mid-program.
Oracle EBS HRMS stores employee data across PER_ALL_PEOPLE_F (personal data), PER_ALL_ASSIGNMENTS_F (assignments), PER_ADDRESSES (addresses), and PAY_ELEMENT_ENTRIES_F (payroll elements), while Workday uses a unified worker record with effective-dated business processes. Mine maps Oracle's normalized HR tables to Workday's worker model with full history translation.

How Mine automates your Oracle EBS HR to Workday migration
Mine profiles all Oracle HRMS date-tracked tables and reconstructs the event timeline for Workday — converting Oracle's begin/end date records into Workday's effective-dated business process events.
Oracle org hierarchies are mapped to Workday supervisory organizations with reporting line validation and position management alignment.
Payroll element entries are mapped to Workday earnings and deduction codes with input value translation — and Mine validates pay calculation accuracy against Oracle's payroll results before cutover.
Oracle DFFs on HR tables are profiled from the repository metadata and mapped to Workday custom fields — each DFF context-segment combination gets its own mapping rule.

Common challenges migrating from Oracle EBS HR to Workday
Oracle date-tracked tables to Workday effective dates
Oracle HRMS uses date-tracked tables (EFFECTIVE_START_DATE / EFFECTIVE_END_DATE on PER_ALL_PEOPLE_F, PER_ALL_ASSIGNMENTS_F) that store full history of every change. Workday uses effective-dated transactions within business processes. Converting Oracle's date-tracked records to Workday's event-based history requires careful timeline reconstruction.
Explore related migrations →Oracle org hierarchy to Workday supervisory organizations
Oracle uses HR_ALL_ORGANIZATION_UNITS with a parent-child hierarchy and multiple organization classifications. Workday uses supervisory organizations with a different hierarchy model. The mapping affects reporting lines, security groups, and approval chains — and must be designed before employee data migrates.
Explore related migrations →Payroll element entries to Workday earnings and deductions
Oracle's payroll uses element types and element entries (PAY_ELEMENT_ENTRIES_F) with complex input values. Workday uses compensation plans, earning codes, and deduction codes. The element-to-earning/deduction mapping must preserve payroll calculation accuracy for the first Workday pay run.
Explore related migrations →Oracle DFFs on HR tables
Oracle HRMS tables commonly have Descriptive Flexfields storing custom HR data (employee classification, union membership, custom leave balances). Each DFF segment must be mapped to a Workday custom field or custom object. Mine reads the DFF metadata from Oracle's repository to decode what each attribute column stores.

The cost of manual Oracle EBS HR to Workday migration
These migrations are managed by HR consulting firms over 12–18 months. Oracle's complex date-tracked tables, custom DFFs on HR tables, and country-specific legislation make the data conversion workstream particularly labor-intensive.
