Migrating from Oracle Fusion HCM to Rippling is one of the fastest-growing HR transformation projects in 2026. Oracle HCM is powerful — but for mid-market companies that don't need multi-country payroll or ERP integration, the complexity and cost often outweigh the benefits. Rippling gives you HR + IT + payroll in a single platform, implements in weeks rather than months, and costs a fraction of Oracle licensing.
This guide is written from the Oracle side: we'll cover the exact tables you need to extract, how to handle Oracle's effective-dating quirks, the data mapping to Rippling's model, and the realistic timeline and cost you should budget.
Rippling is a strong Oracle HCM replacement if most of the following apply:
Rippling's advantages over Oracle for this profile: 4–6x lower total cost, 10–15x faster implementation, a modern UI that employees actually adopt, and native IT device management bundled in.
Stay on Oracle if you have payroll in 20+ countries, complex Fast Formula business rules that drive payroll outcomes, deep Oracle ERP integration with Financials/SCM, or more than 10,000 employees with highly customized workflows. For those scenarios, the migration complexity and feature gap don't justify the switch.

Oracle Fusion HCM stores HR data across dozens of tables. For a Rippling migration, you need these core datasets:
| Oracle Table | What It Contains | Rippling Equivalent |
|---|---|---|
PER_ALL_PEOPLE_F |
Employee demographics — name, DOB, national identifier, gender, ethnicity | Employee profile fields |
PER_ALL_ASSIGNMENTS_M |
Job assignments — title, department, location, grade, FTE — date-effective history | Job information (current state only) |
PER_WORK_RELATIONSHIPS |
Employment relationships — hire date, termination date, worker type | Employment record / start and end dates |
PER_ASSIGNMENT_SUPERVISORS_F |
Reporting manager hierarchy | Reports-to field on each employee |
PER_PHONES |
Employee phone numbers by type (work, mobile, home) | Contact fields |
PER_ADDRESSES_F |
Employee addresses (home, work) | Address fields (required for payroll tax) |
| Oracle Table | What It Contains | Rippling Equivalent |
|---|---|---|
PAY_ELEMENT_ENTRIES_F |
Salary, bonus, and compensation element entries | Compensation (base salary + one-time payments) |
PAY_ELEMENT_ENTRY_VALUES_F |
Actual values for compensation elements (amounts, rates) | Compensation values |
BEN_PERSON_BENEFIT_EXPRS_F |
Benefit plan enrollments and coverage elections | Benefits elections (if migrating mid-year) |
PER_ABSENCE_ATTENDANCES |
Absence history — type, start date, end date, days/hours | Time-off history (for accrual balance carryover) |
| Oracle Table | Notes |
|---|---|
PAY_RUN_RESULTS |
Historical payroll run results — reference only, doesn't migrate to Rippling |
PER_ALL_POSITIONS |
Position hierarchy — relevant if Rippling's position management feature is used |
ORG_ORGANIZATION_EFF_F |
Department and organization hierarchy — import into Rippling's department tree |
Use the OTBI "Workforce Management – Worker Assignment Real Time" subject area to export current-state assignments without writing SQL. For historical data, query the underlying tables directly via BI Publisher or Oracle BIP data model. PER_ALL_ASSIGNMENTS_M gives you the cleanest assignment history — prefer it over PER_ALL_ASSIGNMENTS_F for migrations.
This is the single biggest source of migration bugs. Oracle stores changes as date-range rows — every update to an assignment creates a new row with EFFECTIVE_START_DATE and EFFECTIVE_END_DATE. Rippling expects a single current-state record per employee.
The problem: A typical Oracle employee record in PER_ALL_ASSIGNMENTS_M has 5–20+ rows, one per job change. If you export all rows naively, you'll import 20 records per employee into Rippling and cause chaos.
The fix: Filter to current state before export:
-- Get current-state assignment for all active employees
SELECT
paam.person_id,
paam.assignment_id,
paam.job_id,
paam.department_id,
paam.location_id,
paam.grade_id,
paam.assignment_status_type,
paam.effective_start_date,
paam.effective_end_date,
papf.full_name,
papf.date_of_birth,
papf.national_identifier
FROM per_all_assignments_m paam
JOIN per_all_people_f papf
ON papf.person_id = paam.person_id
AND TRUNC(SYSDATE) BETWEEN papf.effective_start_date AND papf.effective_end_date
WHERE TRUNC(SYSDATE) BETWEEN paam.effective_start_date AND paam.effective_end_date
AND paam.assignment_type = 'E'
AND paam.assignment_status_type = 'ACTIVE'
AND paam.effective_latest_change = 'Y';The effective_latest_change = 'Y' filter ensures you only get the latest version of each row within the current date range — critical when Oracle has multiple rows with the same effective dates after corrections.
Rippling doesn't natively store Oracle-style effective-dated history. You have two options:
Rippling uses different field names and value enumerations than Oracle. Here's the key mapping:
| Oracle Field | Oracle Example | Rippling Field | Rippling Value |
|---|---|---|---|
ASSIGNMENT_TYPE |
E (Employee), C (CWK) | Worker Type | Employee, Contractor |
EMPLOYMENT_CATEGORY |
FR (Full-time Regular), PR (Part-time Regular) | Employment Type | Full Time, Part Time |
EXEMPT_INDICATOR |
Y / N | FLSA Status | Exempt / Non-Exempt |
BARGAINING_UNIT_CODE |
Custom lookup values | Custom field | Map to Rippling custom field |
GRADE (from HR_GRADES) |
Grade 1–10 or custom codes | Level / Band | Map or create matching values |
Department from ORGANIZATION_NAME |
HR, Finance, Engineering | Department | Must pre-create in Rippling |
Location from LOCATION_CODE |
HQ-NYC, REMOTE, EMEA-LON | Work Location | Must pre-create in Rippling |
Key rule: Create departments and locations in Rippling before importing employees. Rippling imports fail if referenced values don't exist. Oracle lookup codes that don't map to standard Rippling values need a custom field or manual mapping document.
Audit your Oracle HCM instance: headcount, countries, data quality issues. Extract Tier 1 tables and do initial profiling — identify lookup code values, custom flexfields, and any non-standard configurations. Assign a data owner for each Oracle table.
Write and test transformation scripts (Python, SQL, or Excel + Power Query) to flatten effective-dated records, map Oracle lookup codes to Rippling equivalents, and build the import CSVs. Validate against a sample of 50–100 employee records manually.
Configure Rippling: set up departments, locations, job titles, compensation bands, benefit plans, time-off policies, and custom fields. Get payroll tax registrations in place for all states/countries where you have employees. Rippling's implementation team will guide this.
Import into a Rippling test environment. Validate all employee records, run test payroll for one pay cycle (compare gross vs. Oracle). Identify and fix data issues — expect 1–3 cycles of finding and fixing mapping errors before the data is clean.
Pick a payroll cutover date (usually beginning of a quarter or benefit year). Notify employees. Set up IT onboarding in Rippling (device management, app provisioning). Train HR admins on Rippling workflows. Archive Oracle data to CSV/SharePoint.
Import final data refresh (delta since test import). Run first live payroll in Rippling while Oracle is still active. Confirm match. Cut over completely. Keep Oracle in read-only mode for 30–60 days for reference.
| Cost Component | Typical Range | Notes |
|---|---|---|
| Rippling implementation (Rippling-provided) | Included for 200+ employees | Rippling assigns an implementation manager |
| Oracle data extraction (internal or consultant) | $5,000–$20,000 | Higher if effective-dating is complex or data quality is poor |
| Transformation scripts and mapping | $5,000–$15,000 | Python/SQL; can be internal if you have technical HR/IT staff |
| Testing and parallel run | $5,000–$15,000 | Plan for 3–4 rounds of validation |
| Change management and training | $2,000–$8,000 | HR admin training + employee comms |
| Total (professional services) | $17,000–$58,000 | Excluding Rippling licensing (typically $8–15/employee/mo) |
Compare that to Oracle HCM's average implementation cost of $250,000–$1,000,000+ for a fresh deployment, and the ROI math is clear for mid-market companies.

Be honest with stakeholders about what you're leaving behind:
PAY_RUN_RESULTS doesn't import to Rippling. Archive in CSV for compliance; Rippling starts fresh from cutover date.PER_ABSENCE_ATTENDANCES doesn't have a clean import path. Provide employees a PDF summary from Oracle before cutover.PER_ALL_PEOPLE_F (demographics), PER_ALL_ASSIGNMENTS_M (job assignments), PER_WORK_RELATIONSHIPS (hire/term dates), PER_ASSIGNMENT_SUPERVISORS_F (managers), PER_PHONES, and PER_ADDRESSES_F. For compensation, add PAY_ELEMENT_ENTRIES_F. For benefits, add BEN_PERSON_BENEFIT_EXPRS_F. Historical payroll (PAY_RUN_RESULTS) is archived but not imported into Rippling.EFFECTIVE_LATEST_CHANGE = 'Y'). The second challenge is mapping Oracle lookup codes — custom values for ASSIGNMENT_TYPE, EMPLOYEE_CATEGORY, grade codes — to Rippling's equivalents.Get a free scoping call with an Oracle HCM migration specialist, or request a Rippling demo to see the platform before committing.
