Pre-built kronos workforce central data migration conversion for Time, Scheduling and Absence. REST API + direct-SQL extractors, multi-year punch streaming, accrual liability reconciliation, FBDI Time Card and HDL Absence emitters. Audit-ready evidence at every load.
The hard part isn't pulling JSON from the WFC REST API. It's translating Kronos's pay-rule-driven data model into Fusion's Time & Labor model without losing FLSA substantiation or breaking union pay agreements.
Kronos Workforce Central, now under UKG ownership since the 2020 Kronos + Ultimate Software merger, presents a data model built around Pay Groups, Pay Rules, Work Rules, Punches (TIMESHEETITEM), Signed Timecards, Accrual Plans, Leave Cases (FMLA/ADA/state PFL), Schedules and Labor Accounts. Oracle Fusion HCM uses a different shape — Workers tied to Pay Groups, Time Categories driving Time Repository rules, Element Entries for payroll, Absence Plans and Cases for leave, and Time Card EFFs for premium pay.
Every kronos workforce central data migration to Oracle Fusion has to bridge those gaps without breaking the audit chain that links a payroll GL journal line back to its original employee punch. Custom REST clients and one-off transformation SQL can do it — but every domain becomes a multi-week negotiation between functional, technical, compliance and union teams. Syntra ETL replaces that with pre-built crosswalks refined across dozens of Kronos WFC conversions.
The same engine handles three deployment scenarios: full WFC replacement (Time + Scheduling + Absence → Fusion Time & Labor + Absence Management), Time-only migration with Scheduling kept temporarily on WFC (common when retail or healthcare operations love the Kronos shift-bidding UI), and the consolidation pattern where Absence migrates to Fusion ahead of Time as a confidence-building first wave.
The transformations Syntra ETL ships pre-built. No custom REST scaffolding, no multi-month bespoke conversion development.
WFC Pay Rules walked, classified by payroll materiality, and routed: FLSA overtime to Time Repository rules, shift differentials to Element Entries via Time Card EFFs, union rules to Time Consumer Sets per CBA.
Multi-year punch volumes streamed via REST API + direct read-only SQL, hash-signed, partitioned Parquet output. Bound to Fusion Time Cards via FBDI with original punch-id preserved for FLSA substantiation.
Accrual balances extracted as-of effective date, YTD earn/take, carryover and cap context. HDL Absence Plan Balance load. Reconciled to the hundredth-of-an-hour for SOX accrual-liability sign-off.
Leave cases (FMLA, ADA, state PFL) with intermittent fragments preserved. Case state, certifications, eligibility carried to Fusion Absence Case — no clock restart for employees mid-leave.
WFC Labor Accounts (location + cost-center + project + work-rule) decomposed to Fusion COA segments and Time Card EFFs. Material reporting splits preserved end-to-end.
Collective Bargaining Agreement pay rules, grievance-relevant timecard edits, and union-specific premium history preserved as evidence metadata for ongoing union audit response.
A repeatable load order that respects Fusion HCM's data dependencies. Skip a step and your Time Card load fails on missing workers or missing Time Consumer Sets.
Fusion enterprise structures, ledgers, BUs, COA segments, Time Consumer Sets, Time Categories, Absence Plans, pay group definitions configured. Loaded via FSM tasks — not user-facing data, but everything downstream depends on it.
Workers (HDL Worker.dat) with pay group and labor account context, Positions, Absence Plan setup. Loaded in dependency order — workers before time cards, absence plans before balances, plans before cases.
As-of effective date balances per accrual code per worker, plus YTD earn/take, carryover and cap context. HDL Absence Plan Balance load. Reconciled before any time card or absence case loads.
Current pay-period time cards and historical punch tail loaded via FBDI Time Card Import. Pay rule outcomes recalculated and validated against WFC signed-timecard register to the cent.
FMLA, ADA, state PFL cases migrated via HDL Absence Case with state preserved. Intermittent fragments, certifications, eligibility carried. Case continuity verified — no employee mid-leave starts the 12-week clock over.
Final delta replay, parallel-pay-cycle reconciliation, sign-off pack (payroll register, accrual liability, FMLA caseload — WFC vs Fusion to the cent and hundredth-of-an-hour). Production cut to Fusion.
Reconciliation-first, audit-ready, Oracle Fusion-native — built for the unique demands of WFM data conversion.
REST API and direct read-only SQL extractors for every WFC domain. No bespoke REST scaffolding, no SQL detective work to find archived punch tables.
Pay rule to Time Category, labor account to COA, accrual code to Absence Plan, schedule template to Fusion Time Setup — refined across dozens of Kronos conversions.
FBDI and HDL payloads validated against current Fusion 26x schema locally. No 6-hour ESS jobs that fail on row 73,000 with an unhelpful Oracle error.
Row-level, sum-level, hash-level reconciliation per pay group per period. Signed evidence pack for SOX, FLSA, state wage law and union audit.
Modified-since watermark deltas through REST. Standard 1–2 pay-cycle parallel pattern supported without manual delta tracking.
Every load produces signed timestamped evidence: WFC source register, Fusion target register, hash signatures, sample-record traces. Audit signs off directly.
Kronos workforce central data migration is the process of moving punches (TIMESHEETITEM), signed timecards, schedules, accrual balances (PTO, sick, vacation, comp time), leave cases (FMLA, ADA, state PFL), pay rule and work rule configurations, and Workforce Analytics reporting context from your WFC tenant into Oracle Fusion HCM Time & Labor, Absence Management and Payroll. The technical heart is two-fold: streaming structured data through the WFC REST API with rate-limit awareness, and bulk-reading historical punch volumes via direct read-only SQL against the WFC TKCS schema. Syntra ETL handles both with pre-built extractors, governed crosswalks for WFC Pay Codes to Fusion Element Entries, and Oracle-validated HDL Worker / FBDI Time Card / HDL Absence Plan Balance output.
The terms get used interchangeably, but the distinction is useful: migration is the end-to-end project (extract + transform + load + reconcile + cutover), while conversion is the transformation layer specifically. Syntra ETL's kronos workforce central data migration conversion engine ships pre-built rules for pay-rule to Fusion Time Category mapping, labor-account translation to Fusion COA, accrual-code to Fusion Absence Plan binding, schedule template translation and leave-case continuity preservation. These are rules that on a consultant-led project would otherwise eat 3–4 months of bespoke REST client and SQL development.
Punch volumes are the single biggest data domain in any kronos workforce central data migration — hundreds of millions of rows for a multi-thousand-employee deployment with 7+ years of FLSA + state wage law retention. The WFC database (TKCS schema, TIMESHEETITEM, EMPLOYEE, ACCRUALBALANCE tables) holds the granular detail. Syntra ETL streams current-period punches through the REST API in parallel (typically 60 calls/min per tenant) and uses direct read-only SQL with rowversion watermarks for historical tail extraction. Output staged as Parquet partitioned by fiscal year and pay group, hash-signed and indexed by punch-id, satisfying FLSA 3-year, state wage law up to 7-year, and IRS 4-year retention with signed access logs.
Yes. WFC pay rules and work rules are the equivalent of an EBS time-policy engine — they drive FLSA overtime, shift differential, meal-break deduction, holiday premium, on-call premium and union-specific calculations. Syntra ETL's Kronos converter walks every active Pay Rule, Work Rule, Holiday Rule, Combination Rule and Wage Profile in the source WFC tenant, identifies which rules drive material payroll outcomes, and proposes Fusion Time & Labor routing: FLSA overtime rules collapse into Fusion Time Categories with Time Repository rules, shift differentials route to Fusion Element Entries via Time Card EFFs, and union contract rules route to Time Consumer Sets per Collective Bargaining Agreement.
Syntra ETL emits Fusion-native load formats for every WFC data domain: HCM Data Loader (HDL) for Worker.dat (employees with pay group and labor account context), Position.dat, AbsencePlanBalance.dat (accrual balances), AbsenceCase.dat (FMLA/ADA cases); FBDI Time Card Import for punch history and signed timecards; FBDI Element Entry for pay-impacting absence and premium pay; and REST API payloads for incremental delta loads during parallel-run and post-cutover. Every payload is validated against the current Oracle Fusion 26x release schema before submission, so validation errors surface locally — not in a 6-hour HCM ESS job that fails on row 73,000.
Every employee, punch and accrual balance extracted from WFC is hashed at the source (Worker hash + punch hashes + accrual hashes). Every record loaded into Fusion is re-hashed post-load. The reconciliation engine compares counts (Workers, punches, accruals, leave cases), sum totals (worked hours, OT hours, accrual liability per code per pay group), and hash signatures per pay group 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: WFC payroll register vs Fusion payroll register to the cent, accrual liability vs accrual liability to the hundredth-of-an-hour, FMLA case count vs count. SOX and union audit sign off directly.
Yes. After the initial bulk load, Syntra ETL captures WFC deltas via the REST API's modified-since watermark on each domain (punches, timecards, accruals, leave cases) and replays them into Fusion through REST APIs. This supports the standard parallel-run pattern: WFC continues taking punches for 1–2 pay cycles while Fusion is validated to the cent. Once HR, payroll and union sign off, new punches cut to Fusion and the WFC tenant moves to read-only archive mode. Critical for the Kronos Private Cloud Dec 2025 deadline: parallel-run windows must close before EOL or the cloud tenant disappears mid-parallel.
FLSA requires 3-year retention of payroll records and 2 years of supporting timecard data, with auditable trace from payroll register back to original punches. State wage laws extend that to 7 years in California, New York and several others. FMLA requires 3-year retention of leave records. Syntra ETL's kronos workforce central data migration preserves the full chain: Fusion payroll GL line → Element Entry → Time Card → original punch, with every hop signed and timestamped. Whether the punch history lands in Fusion or in the long-term Kronos archive, the read-access log is captured for DOL Wage & Hour audit evidence. No reconstruction needed when investigators arrive.
