Pre-built ukg pro + ready data migration for Core HR, Payroll, WFM, Benefits and Talent. UKG Pro REST/SOAP and UKG Ready API extractors, custom pay-component crosswalks to Oracle Payroll Elements, HDL/FBDI emitters, balance-initialisation payloads, row-level reconciliation. Audit-ready evidence at every load.
The hard part isn't pulling JSON from the UKG Pro API. It's translating UKG's worker/payroll/time data model into Oracle Fusion HCM's business-object model without losing IRS/ERISA/FLSA substantiation or breaking the first Fusion pay cycle.
UKG Pro and UKG Ready present cloud-native data models built around Workers and Positions, Pay Statements (with earnings, deductions, taxes, garnishments and YTD balances), Timecards and Schedules (from the Kronos-heritage WFM module), Benefit Enrolments and Dependents, ACA 1095-C records, and the Talent suite (recruiting, performance, learning, succession). Oracle Fusion HCM uses a different shape — Worker and WorkRelationship and Assignment as separate business objects, Element Entries driving Payroll, Time Cards in Oracle Time and Labor, Benefit Plans and Enrolments under Oracle Benefits, and a strict HCM Data Loader (HDL) load order that must be respected.
Every ukg pro + ready data migration to Oracle Fusion has to bridge those gaps without breaking the audit chain that links a GL journal line back to its original pay-period record and timecard punch. Custom SOAP clients and one-off transformation SQL can do it — but every domain becomes a multi-week negotiation between HR, Payroll Ops, Compliance and Finance. Syntra ETL replaces that with pre-built crosswalks refined across UKG conversions.
The same engine handles three deployment scenarios: full UKG replacement (Core HR + Payroll + WFM + Benefits + Talent → Oracle Fusion), payroll-only migration (UKG Payroll → Oracle Payroll with WFM staying on UKG temporarily), and the SMB scenario (UKG Ready → Oracle Fusion HCM Cloud) where the data shapes are simpler but the reconciliation rigour is identical.
The transformations Syntra ETL ships pre-built. No custom SOAP scaffolding, no multi-month bespoke conversion development.
UKG custom pay components walked, classified by payroll materiality, and routed: required components map to Oracle Payroll Earnings/Deduction Elements with matching calculation rules, optional components route to Information Elements, analytical to archive.
Federal, State, FICA, Medicare, supplemental wage tax, plus deduction balances and garnishment running totals translated to HDL Balance Initialization payloads tuned for the first Oracle Fusion pay cycle to reconcile to the cent.
UKG WFM punches, edits and approvals matched to Oracle Time and Labor records with overtime calculation reproduced — so the same gross-pay number falls out of both systems in the parallel-payroll window.
UKG benefit enrolments, dependents and beneficiaries converted to HDL Benefits with plan/option/coverage start dates preserved. ACA 1095-C history routed to archive with full month-by-month coverage evidence.
Recruiting requisitions, applicant pipelines, performance ratings, goals, learning history and succession plans converted to Fusion Recruiting/Performance/Learning HDL objects with applicant-resume and certificate documents preserved.
Worker → pay-component → tax-jurisdiction chain maintained: federal, state, local, SUTA and reciprocal-state context carried through so multi-state quarterly filings continue uninterrupted on the Oracle side.
A repeatable load order that respects HDL's strict business-object dependencies. Skip a step and your worker load fails on missing positions, or your pay-element load fails on missing payroll definitions.
Oracle Fusion enterprise structures, legal entities, ledgers, BUs, COA segments, payroll definitions, element classifications, balance categories, absence plans configured. Loaded via FSM tasks — not user-facing data, but everything downstream depends on it.
Locations, Organizations, Jobs, Grades, Positions loaded in dependency order via HDL Location.dat, Organization.dat, Job.dat, Grade.dat, Position.dat. UKG manager hierarchies preserved as reporting-line relationships.
Workers loaded via HDL Worker.dat with full effective-dated chain (hire, promotion, transfer, termination). WorkRelationships and Assignments link workers to positions, grades and legal employers. Active populations first, then historical terminations.
Oracle Payroll Element Entries loaded via HDL ElementEntry.dat with all UKG pay components mapped through the Element catalogue. HDL Balance Initialization loaded for current-year YTD: Federal, State, FICA, Medicare, SUTA, plus deduction and garnishment balances.
UKG WFM timecards and schedules loaded to Oracle Time and Labor. Absence plans and accrual balances loaded via HDL Absence. Benefit plans, enrolments, dependents and ACA history loaded via HDL Benefits. Recruiting, performance and learning data follow.
One full pay cycle run in parallel (UKG + Oracle Payroll). Gross, tax, deduction and net reconciled to the cent per worker per element. Sign-off pack issued. Production cut to Oracle Payroll; UKG moves to read-only archive mode.
Every Oracle Fusion load template that matters in a UKG migration — already mapped to the UKG Pro and UKG Ready source fields.
UKG Worker → Oracle PersonName, PersonLegislativeData, Person, WorkRelationship, Assignment. Effective-dated chain preserved across hire, promotion, transfer, leave and termination events.
UKG Position → Oracle Position with seat headcount, location, organisation, hiring status and incumbent assignment chain. Position hierarchies preserved for org-chart continuity.
UKG pay components → Oracle Payroll Element Entries with calculation values, effective dates and recurring/non-recurring classification. Garnishment elements include court-order metadata.
UKG YTD balances → Oracle Payroll Balance Initialization for Federal, State, FICA, Medicare, SUTA, plus deduction and garnishment running totals — tuned for cent-perfect first-cycle reconciliation.
UKG benefit plans, options, enrolments, dependents, beneficiaries and life-event history → Oracle Benefits HDL with full ACA 1095-C month-by-month coverage evidence preserved.
UKG absence plans, accrual balances and FMLA leave records → Oracle Absence Management HDL. FLSA wage-and-hour evidence preserved through the timecard chain.
UKG Pro + Ready data migration is the end-to-end process of moving workers, positions, jobs, grades, organisations, payroll registers (earnings, deductions, taxes, garnishments, YTD balances), timecards and schedules from UKG Pro Workforce Management, benefit plan enrolments and dependents, ACA 1095-C records, recruiting pipelines, performance and learning history out of your UKG Pro and UKG Ready tenants into Oracle Fusion HCM, Oracle Payroll, Oracle Time and Labor, Oracle Benefits and Oracle Talent. The technical heart is two-fold: streaming structured data through UKG Pro REST and SOAP web services plus UKG Ready APIs, and bulk-converting that data into Oracle-native HDL .dat files and FBDI templates. Syntra ETL handles both with pre-built extractors, governed crosswalks for UKG pay components to Oracle Payroll Elements, and Oracle-validated HDL output.
The terms get used interchangeably, but the distinction is useful: ukg pro + ready data migration is the end-to-end project (extract + transform + load + reconcile + cutover), while conversion is the transformation layer specifically. Syntra ETL's UKG data conversion engine ships pre-built rules for UKG Job to Oracle Job mapping, UKG Pay Component to Oracle Payroll Element translation, UKG Deduction Code to Oracle Deduction Element routing, UKG Position to Oracle Position binding, timecard punch matching, BI report metadata preservation, and benefit-plan-to-Oracle-Plan crosswalks. These are rules that on a consultant-led project would otherwise eat 3–4 months of bespoke SOAP/REST client and SQL development.
Payroll history is the largest structured data volume in any UKG migration — pay-period registers across 8–10 years of history, with hundreds of earnings, deductions and tax records per worker per pay period. For a 10,000-worker bi-weekly population that's roughly 2.6M pay-period records and tens of millions of detail rows. Syntra ETL streams payroll history through UKG Pro Payroll Web Services in parallel (respecting UKG's published rate limits), preserves the original UKG pay-period-id and pay-statement-id, and stages records to cloud object storage with hash signatures. For Fusion-target loads, current YTD balances are routed to Oracle Payroll via HDL Balance Initialization. For archive-target loads, historical pay statements stay in object storage indexed by pay-period-id, satisfying IRS Pub 15 4-year retention plus ERISA and state wage-law longer windows.
Yes. UKG custom pay components and custom deduction codes are the equivalent of EBS Element Types — they drive earnings calculation, deduction processing, tax categorisation and GL coding. Syntra ETL's UKG converter walks every active custom pay component and deduction code in the source tenant, identifies which ones drive material payroll calculations versus which are analytical-only, and proposes routing to the Oracle Payroll Element catalogue: required components map to Oracle Earnings or Deduction Elements with matching calculation rules, optional components route to Information Elements, and analytical-only components route to the long-term UKG archive with metadata preserved for retro queries. Garnishment elements get special handling to preserve court-order substantiation and remaining-balance state.
Syntra ETL emits Fusion-native load formats for every UKG data domain: HCM Data Loader (HDL) .dat files for Worker, WorkRelationship, Assignment, Position, Job, Grade, Organization, Location and Element Entry business objects; HDL Balance Initialization for opening YTD payroll balances; HDL Absence Plan and Absence Record for time-off; HDL Benefits for plan enrolments and dependents; FBDI for GL-posting integrations and any Payables/Receivables sub-ledger touches. Every payload is validated against the current Oracle Fusion HCM 26x release schema before submission, so validation errors surface locally — not in a multi-hour HDL load that fails on row 47,000 with a cryptic SVC-FCO-WRK error.
Every worker, pay-period record and timecard extracted from UKG is hashed at the source (header hash + line hashes + balance hashes). Every record loaded into Oracle Fusion HCM and Oracle Payroll is re-hashed post-load. The reconciliation engine compares counts (workers, pay periods, timecards, accruals), sum totals (gross, tax, deduction, net per worker per pay period) and hash signatures per legal entity per period. Any record that fails Fusion validation is captured with the exact field-level reason ready for bulk fix. Output is a signed timestamped reconciliation pack: UKG payroll register vs Oracle Payroll register to the cent, UKG headcount vs Oracle worker count, UKG timecard hours vs Oracle Time and Labor hours. Internal audit signs off on the pack directly.
Yes — and for payroll specifically, a parallel-payroll cycle is mandatory before go-live. After the initial bulk load, Syntra ETL captures UKG deltas via the API's modified-since watermark on each domain (workers, payroll registers, timecards) and replays them into Oracle Fusion via HDL. The standard pattern is: one full pay cycle run in parallel (UKG + Oracle Payroll), gross/tax/deduction/net reconciled to the cent per worker per element, Compliance and Payroll Ops sign-off, and then the next cycle runs in Oracle Payroll only. UKG moves to read-only archive mode. Timecard collection cuts over at the start of the parallel cycle so the WFM data feeding Oracle Payroll is captured natively in Oracle Time and Labor.
IRS Pub 15 requires payroll records for 4 years; ERISA requires benefit-plan records for 6 years (or longer for active participants); FLSA requires wage-and-hour records (timecards, schedules, exemption classifications) for 3 years; state wage laws extend many of these. Syntra ETL's ukg pro + ready data migration preserves the full chain: GL line in Oracle Fusion → Payroll Distribution → Pay Statement → Pay Component → original UKG pay-period record, with every hop signed and timestamped. Whether the historical pay statement lands in Oracle Payroll YTD balances or in the long-term UKG archive, the read-access log is captured for IRS, ERISA and FLSA audit evidence. No reconstruction needed when auditors arrive.
