The hard part isn't pulling JSON from Workday's REST API. It's translating Workday's effective-dated in-memory object model into Fusion HCM's date-tracked relational model without losing worker history, calculated-field logic or payroll-results substantiation.
Workday HCM presents a proprietary cloud-native data model built around objects: Worker, Position, Job Profile, Supervisory Organization, Compensation Plan, Benefit Enrollment, Time Off Plan, Payroll Result. Each object is effective-dated, so a single worker carries dozens of versioned rows across a multi-year tenure. Oracle Fusion HCM uses a different shape — date-tracked Assignments tied to Persons, Position records tracked separately, Element Entries for pay components, all in a relational schema with referential integrity enforced at the database layer.
Every workday hcm data migration to Oracle Fusion has to bridge those gaps without breaking the worker-history chain that links a current paycheck back to the original date-of-hire. Custom REST/SOAP clients and one-off transformation SQL can do it — but every domain becomes a multi-month negotiation between HRIS, payroll, comp, benefits and compliance teams. Syntra ETL replaces that with pre-built crosswalks refined across dozens of Workday migrations.
The same engine handles three deployment scenarios: full Workday HCM replacement (Core HR + Comp + Benefits + Absence + Talent + Time + Payroll → Fusion), HCM-only migration with Workday Payroll kept (common where the customer is on Workday Payroll US/Canada/UK/France and the timing isn't right to switch payroll providers), and the consolidation pattern where Workday Talent and Recruiting modules cut to Fusion ahead of Core HR.
The transformations Syntra ETL ships pre-built. No custom REST/SOAP scaffolding, no multi-month bespoke conversion development.
Workday's effective-dated worker versions reconstructed as Fusion date-tracked Assignments. Full transition history (hire, promotion, comp change, position change, manager change) preserved with as-of dates intact.
Every calculated field in active use inventoried, classified (eligibility, accrual math, comp ratio, geographic differential) and rebuilt as Fusion Fast Formula with side-by-side validation against the Workday-evaluated value.
Workday Payroll results (paycheck headers + result lines + tax detail) converted to Fusion Element Entries with paycheck identifier preserved as cross-reference. W-2/T4/P60 substantiation chain unbroken.
Enrollment events, life-event changes, dependent/beneficiary history, COBRA continuation periods — converted to Fusion Benefits HDL with ACA 1095-C-relevant detail preserved for 3-year retention.
Workday custom business processes inventoried, classified (approval routing, condition rules, sub-process orchestration), and rebuilt in Fusion AMX/BPM with the same approver hierarchy and condition logic.
Workday Domain Security Policies translated to Fusion HCM data roles with row-level security predicates that match the source visibility model. No over-broad access during cutover.
A repeatable load order that respects Fusion HCM's data dependencies. Skip a step and your Worker load fails on missing organizations, positions or jobs.
Fusion enterprise structures, legal entities, business units, payrolls, COA segments, element classifications, benefit programs configured via FSM tasks. Not user-facing data, but everything downstream depends on it.
Locations, departments, divisions, supervisory organizations, cost-center organizations — loaded via HDL Department.dat and Location.dat. Hierarchy graph preserved exactly as in source.
Positions, job families, job profiles, grades — loaded via HDL Position.dat and Job.dat with the full job-profile-to-grade-to-step hierarchy preserved.
Workers and date-tracked assignments loaded via HDL Worker.dat/Person.dat/Assignment.dat. Effective-date history preserved per worker — every promotion, comp change and manager change reconstructable post-load.
Compensation plan assignments, element entries (pay components), benefit enrollments, absence balances, payroll results (where Workday Payroll in scope) — loaded with Fast Formula rebuilds and benefit-event reconstruction.
Final delta replay, parallel-pay-period reconciliation, sign-off pack (headcount, YTD payroll gross/net/tax, benefit premium totals — Workday vs Fusion to the cent). Production cut to Fusion.
No custom adapters, no SQL*Loader scripts. Validated against the current Fusion 26x HCM schema before submission.
HDL Worker.dat for worker records, Person.dat for person detail, PersonalRelationship.dat for dependents and beneficiaries — emitted with Workday effective-date history preserved.
HDL Assignment.dat for date-tracked assignment history, Position.dat for position records with full effective-dating — reconstructed from Workday's job/position/assignment object chain.
HDL Element.dat for pay element definitions and ElementEntry.dat for pay-component entries — including payroll-results conversion for Workday Payroll customers.
Benefit plan enrollment files, dependent/beneficiary assignment, COBRA continuation periods — full benefit-event history preserved for ACA 1095-C 3-year retention.
Absence plan balances, accrual rules, time-off request history — converted to Fusion Absence Management HDL with multi-year balance history intact.
Workday REST v40+ change-event subscriptions on workers, organizations, positions and assignments — replayed into Fusion via REST API for parallel-run delta capture and post-cutover sync.
Workday hcm data migration is the process of moving HR records — workers, positions, jobs, organizations, compensation plans, benefit enrollments, absence balances, time blocks, performance reviews, payroll results — from your Workday HCM tenant into Oracle Fusion HCM. The technical heart is twofold: streaming Workday's object data through REST API v40+, SOAP Web Services, RaaS (Reports as a Service) and EIB (Enterprise Interface Builder), and re-shaping that object data into Fusion's relational HCM structure. Syntra ETL handles both with pre-built extractors, governed crosswalks for Workday calculated fields to Fusion Fast Formulas, and Oracle-validated HDL Worker.dat, Person.dat, Position.dat, Assignment.dat and ElementEntry.dat output.
The terms get used interchangeably, but the distinction is useful: migration is the end-to-end programme (extract + transform + load + reconcile + cutover), while conversion is the transformation layer specifically. Syntra ETL's Workday data conversion engine ships pre-built rules for object-to-relational reshaping, calculated-field to Fast Formula translation, custom business-process to AMX rebuild, Domain Security Policy to Fusion HCM data-role mapping, and payroll-results to Element Entries conversion. These are rules that on a consultant-led project would otherwise eat 4–6 months of bespoke REST/SOAP development and SQL transformation.
Workday's worker record is heavily effective-dated — every change to job, position, comp, location, manager generates a new effective-dated version of the worker object. A 10-year tenured worker can carry hundreds of effective-dated rows. Syntra ETL's REST v40+ extractor pulls the full effective-date version chain per worker (not just current state), preserves the as-of date for each transition, and converts to Fusion HCM's date-tracked assignment model so the worker's complete career history is reconstructable post-cutover. This is critical for SOX, EEO-1 historical filings, and ex-employee disputes that look back years.
Yes. Workday Comp plans, eligibility rules, grades, steps, pay components and one-time payments all extract via SOAP and RaaS. The hard part is calculated comp ratios and eligibility logic — these are Workday calculated fields evaluated in Workday's engine. Syntra ETL inventories every calculated field driving compensation, classifies (range-penetration math, grade-midpoint comp ratio, geographic differential, percent-of-target), and produces a Fusion Fast Formula rebuild for each. The comp plan structure (plan → grade → step → pay component) converts to Fusion's Compensation Plan/Grade/Step/Element hierarchy with full eligibility migration.
Syntra ETL emits Fusion-native load formats for every Workday HCM data domain: HCM Data Loader (HDL) Worker.dat for worker records, Person.dat for person details, PersonalRelationship.dat for dependents and beneficiaries, Assignment.dat for assignments with effective-date history, Position.dat for positions, Element.dat / ElementEntry.dat for pay components and payroll element entries, Benefit Plan / Enrollment HDL files for benefits, AbsenceAccrual.dat for absence balances. Plus REST API payloads for incremental delta loads during parallel-run. Every payload is validated against the current Fusion 26x HCM release schema before submission.
Every worker, position, organization, comp record and payroll-result row extracted from Workday is hashed at the source. Every record loaded into Fusion HCM is re-hashed post-load. The reconciliation engine compares counts (workers, assignments, comp records, payroll-result lines), aggregate amounts (annual base, payroll YTD gross/net/tax by GL account, benefit premium totals) and hash signatures per business unit per pay period. Any record that fails Fusion validation is captured with field-level reason ready for bulk fix. Output is a signed timestamped reconciliation pack: Workday headcount vs Fusion headcount, Workday YTD payroll vs Fusion YTD payroll to the cent. Internal audit signs off on the pack directly.
Yes. After the initial bulk load, Syntra ETL captures Workday deltas via REST API v40+ change-event subscriptions on workers, organizations, positions and assignments — and via incremental EIB extracts for payroll results. Deltas replay into Fusion through HDL incremental loads and REST API calls. This supports the standard parallel-run pattern: Workday continues taking HR transactions for 1–2 pay-period cycles while Fusion is validated against the cent on payroll, headcount and benefit premiums. Once HR ops, payroll, comp and benefits sign off, new transactions cut to Fusion and the Workday tenant moves to read-only archive mode.
SOX requires 7-year retention of payroll records with auditable trace from GL entry back to the originating employee transaction. EEO-1 requires 3-year retention of employment-category demographics. IRS Form W-2 substantiation requires 4-year retention of payroll-results detail. Syntra ETL's workday hcm data migration preserves the full chain: GL line in Fusion → Element Entry → Worker Assignment → Effective-Dated History → Original Workday object. The hash-signed reconciliation pack is the SOX audit evidence; EEO-1 demographic snapshots are preserved as part of the worker history extract; W-2 substantiation maps payroll results to Fusion Element Entries with the original Workday paycheck identifier retained as cross-reference.
