Integrated ukg pro + ready hr, payroll, workforce, time migration treating the four domains as a coupled bundle. Synchronised effective-dating, cent-perfect parallel-payroll, FLSA + state wage law evidence end-to-end. Pro + Ready + legacy Pro Time + modern UKG Pro Workforce Management.
Generic HCM migration playbooks treat HR, payroll, workforce management and time as adjacent domains. In UKG Pro and UKG Ready they are tightly coupled — a change in one ripples through the others within the same tenant architecture.
UKG Pro carries Pro HR (the post-merger evolution of UltiPro covering worker master and effective-dated chain), Pro Payroll (gross-to-net with multi-state tax engine and IRS/DOL/ACA/ERISA filing), Pro Workforce Management (formerly UKG Dimensions / Kronos Workforce Dimensions, covering timecards and schedules) and Pro Time (the legacy UltiPro Time product that some customers still run). UKG Ready combines Core HR, Payroll, Time and Scheduling on a single SaaS platform for SMB customers. In both product lines the four domains share effective-dated events: a worker's hire date drives earnings-element eligibility in Payroll, timecard-pay-rule eligibility in Workforce Management, and accrual-plan eligibility in Time. Migrating one domain in isolation breaks the others.
The Syntra ETL ukg pro + ready hr, payroll, workforce, time migration playbook treats the four as an integrated bundle. A single effective-dated event log per worker drives synchronised HDL load ordering on the Oracle Fusion HCM target side. Hire applies atomically across Worker / WorkRelationship / Assignment + ElementEntry + TimeCardEntry + AbsencePlan. Promotion applies atomically across the four. Transfer, leave-of-absence, return-from-leave, termination and rehire each apply atomically across the four. The Payroll Director and the HR Systems lead co-sign synchronised effective-date integrity before parallel-payroll begins.
The same playbook covers all four UKG WFM variants in the field: customers on the modern UKG Pro Workforce Management REST API, customers on the legacy UltiPro Time SOAP endpoints, customers on UKG Ready's integrated Time module, and customers running hybrid scenarios during their own internal UKG WFM consolidation. The Oracle Time and Labor target accepts the data consistently regardless of which UKG WFM variant the customer started from.
Each synchronisation point is a place where independent domain migrations fail and a coupled-bundle migration succeeds.
Hire / promotion / transfer / leave / return / termination / rehire applied atomically across Worker + Payroll + WFM + Time. Single event log drives synchronised HDL load order.
Pro Payroll earnings element eligibility ties to Pro HR effective-dated assignment. Element entry effective dates must match worker assignment effective dates or payroll calculation fails.
Pro Workforce Management timecard pay rules tie to Pro HR exempt/non-exempt classification + Pro Payroll element catalogue. FLSA overtime calculation depends on synchronised classification.
Pro Time accrual plan eligibility ties to Pro HR location + position + Pro Payroll legal entity. State-specific accrual rules (California PTO, NY PFL, MA paid sick) apply correctly only with synchronised eligibility.
Pro Benefits enrolments tie to Pro HR life events; Pro HR FMLA leave records tie to Pro WFM timecard absence records and Pro Payroll continuation rules. ACA 1095-C generation depends on all three.
IRS / DOL / ACA / ERISA / I-9 / USERRA evidence chains span all four domains. Worker → Pay Statement → Timecard → Accrual chain preserved end-to-end with hash signatures.
A repeatable, governed playbook with hard deliverables and signed sign-offs at each stage.
Pro HR + Pro Payroll + Pro Workforce Management + Pro Time inventoried as a coupled bundle. Custom pay components, custom timecard pay rules, custom accrual plans, custom person fields all mapped to their cross-domain dependencies.
Field-level mappings configured with cross-domain coupling preserved. Hire date in HR drives element entry start date in Payroll, timecard pay rule start date in WFM, accrual eligibility start date in Time. Mapping store enforces consistency.
Single effective-dated event log per worker built from the four UKG domains. Each event tagged with all four domain impacts. HDL load ordering generated from the event log so target Oracle Fusion HCM state reflects the same coupling.
User acceptance testing with all four domains loaded together. Synchronised effective-dating verified per worker. Pro Payroll gross-to-net reproduced against UKG. Pro Workforce Management overtime calculations reproduced. Pro Time accrual balances reproduced.
One full pay cycle in parallel UKG + Oracle Payroll covering the full coupled bundle. Worker effective-dating, payroll calculations, timecard hours and accrual usage all reconciled per worker per pay period.
All four domains cut over together at pay-period boundary. UKG tenant moves to read-only across all four. PEPM subscription cancellation issued under contract notice period before anniversary.
Six retention regimes covered end-to-end across the coupled-bundle migration.
Pro Payroll pay-period registers, YTD balances, employer/employee tax detail, W-2/W-2c/941/940 evidence (4 years). Pro Benefits ACA 1095-C month-by-month evidence and Pro HR FTE calculation evidence (3+ years).
Pro Workforce Management timecard punches, overtime calculations, exempt/non-exempt classification evidence preserved per state (FLSA 3 years + state extensions: California 8, NY 6, MA 3).
Pro Payroll retirement contribution detail (401(k), 403(b), pension, profit-sharing). Pro Benefits 401(k) plan administration evidence. Hardship distribution, loan history, Form 5500 evidence (6 years).
Pro HR I-9 form chain with reverification records. E-Verify case results (DHS retention). USERRA reemployment evidence preserved across Pro HR + Pro Workforce Management leave records.
Pro HR FMLA leave eligibility + Pro Workforce Management absence records. ADA accommodation history. State paid family leave (NY PFL, California PFL, MA PFML) evidence preserved per state.
Pro HR EEO categorisation, ethnicity, gender, veteran status, job-category mapping (EEO-1 4-year retention; VETS-4212 protected-veteran reporting).
Generic HCM migration playbooks treat HR, payroll, workforce management and time as adjacent domains. UKG Pro + Ready HR, payroll, workforce, time migration is structurally different because the four domains are tightly coupled in the UKG data model — a worker's effective-dated chain in Pro HR drives pay component eligibility in Pro Payroll, drives timecard pay rules in Pro Workforce Management (formerly UKG Dimensions), drives accrual plan eligibility in Pro Time. A change in one domain ripples through the others. The Syntra ETL ukg pro + ready hr, payroll, workforce, time migration playbook treats the four as an integrated bundle with synchronised effective-dating, coupled mapping artefacts and parallel-payroll cent-perfect reconciliation across all four domains simultaneously.
Pro HR (the core HR module in UKG Pro, the post-merger evolution of Ultimate Software UltiPro) carries the workforce master: workers, positions, jobs, grades, organisations, locations, work relationships, manager hierarchies, custom person fields, custom job fields, EEO categorisation, USERRA veteran status, ADA accommodation history, FMLA leave eligibility, I-9 / E-Verify status, signed offer letters, signed handbook acknowledgements, and the full effective-dated chain across hire / promotion / transfer / leave-of-absence / return-from-leave / termination / rehire. The Syntra ETL ukg pro + ready hr, payroll, workforce, time migration playbook converts the Pro HR domain to Oracle Fusion HCM through HDL Worker.dat + WorkRelationship.dat + Assignment.dat with full effective-dated chain preserved.
Pro Payroll (the payroll engine in UKG Pro) carries gross-to-net calculation, multi-state tax engine, supplemental wage tax treatment, garnishment processing with court-order substantiation, retirement-plan contribution processing (401(k), 403(b), pension, profit-sharing), HSA / FSA / commuter benefit processing, ACH direct deposit, IRS EFTPS tax deposit, state-tax-authority deposit, SUTA per state, local tax per jurisdiction, employer-side payroll taxes, W-2 / W-2c / W-3 / 941 / 940 / state SUTA returns / state withholding returns generation. The Syntra ETL ukg pro + ready hr, payroll, workforce, time migration converts the Pro Payroll domain through HDL ElementEntry.dat + BalanceInitialization.dat with cent-perfect parallel-payroll reconciliation as the go-live gate.
Pro Workforce Management — formerly UKG Dimensions / Kronos Workforce Dimensions — is the modern workforce management product covering timecards, punches, edits, approvals, schedules, accrual plans, FMLA leave tracking, USERRA reemployment evidence, exempt/non-exempt classification evidence, meal-and-rest-break records (where state law requires — California, NY, MA and others), tip-credit calculations, minimum-wage compliance evidence and the full FLSA wage-and-hour evidence base. The Syntra ETL ukg pro + ready hr, payroll, workforce, time migration converts the Pro WFM domain to Oracle Time and Labor through OIC integration patterns plus HDL Absence.dat for accrual balances. FLSA + state-wage-law evidence preserved end-to-end with hash-signed punch chain.
UKG Pro Time refers to the legacy time-and-attendance product (formerly UltiPro Time) that some UKG Pro customers still run, separately from the modern UKG Pro Workforce Management (formerly UKG Dimensions) product. Customers on legacy Pro Time have a simpler timecard surface with the older WFM endpoints; customers on modern UKG Pro Workforce Management have the more advanced REST API and additional schedule-optimisation features. The Syntra ETL ukg pro + ready hr, payroll, workforce, time migration playbook supports both — legacy Pro Time via the older WFM endpoints, modern Pro Workforce Management via the newer REST surface. Both route to Oracle Time and Labor on the Fusion side, with FLSA evidence preservation regardless of which UKG WFM variant the customer runs.
Synchronised effective-dating is the most consequential challenge in a UKG Pro + Ready HR, payroll, workforce, time migration. A worker's hire date in Pro HR has to match the corresponding earnings-element-eligibility start date in Pro Payroll, the timecard-pay-rule-eligibility start date in Pro Workforce Management, and the accrual-plan-eligibility start date in Pro Time. The Syntra ETL playbook treats the four domains as a coupled bundle with a single effective-dated event log per worker — every hire / promotion / transfer / leave / return-from-leave / termination / rehire event applies atomically across all four domains on the Oracle Fusion HCM target side via HDL load ordering. The Payroll Director and the HR Systems lead co-sign the synchronised effective-date integrity verification before parallel-payroll begins.
UKG Ready combines Core HR, Payroll, Time and Scheduling on a single SaaS platform — the four domains are even more tightly coupled than in UKG Pro because they share a single tenant architecture. The Syntra ETL ukg pro + ready hr, payroll, workforce, time migration playbook handles UKG Ready through the Ready REST API with a unified extraction job that pulls all four domains in coordinated dependency order, then routes to Oracle Fusion HCM via HDL with the same synchronised effective-dating discipline as Pro. SMB Ready migrations typically complete faster than Pro migrations (8–12 weeks vs 12–18 weeks) because the customisation surface is tighter — but the reconciliation rigour is identical.
