Purpose-built ETL platform for the kronos workforce central to oracle fusion migration — Time, Scheduling, Absence. REST API + direct-SQL extractors, multi-year punch history, accrual liability reconciliation. 40–60% faster than consultant-led programmes. Built around the Kronos Private Cloud Dec 2025 and on-prem Mar 2027 sunset dates.
Most WFC to Fusion projects don't slip on the API extract. They slip on pay-rule translation, punch-history volume, accrual reconciliation and the deadline pressure of the Kronos EOL.
Kronos Workforce Central is a legacy WFM suite. UKG (the Ultimate Kronos Group formed by the 2020 Kronos + Ultimate Software merger) has set firm end-of-life dates: Kronos Private Cloud December 2025, on-prem WFC March 2027. After those dates there is no roadmap, no compliance updates for state wage laws, no new releases. The kronos workforce central to oracle fusion migration is no longer optional for customers who picked Oracle as their HCM strategic direction.
Customers carry a long tail of WFC customization: hundreds of pay rules driving FLSA overtime, shift differential, meal-break deduction and holiday premium calculations; dozens of work rules tied to union contracts and collective bargaining agreements; intricate accrual configurations with carryover caps, eligibility tiers and FMLA fragment tracking; Workforce Analytics reports that operations and HR have come to depend on. Consultant-led migrations spend the first three months just cataloguing what exists.
Syntra ETL inverts the sequence. Pre-built Kronos extractors against WFC REST APIs and direct read-only SQL mean week-one extraction. A discovery engine that crawls the Pay Rule catalog, Work Rule registry, Accrual Plan configuration, Workforce Analytics library and Function Access Profiles produces a complete customization inventory in days. The kronos workforce central to oracle fusion migration conversation that traditionally consumes a quarter now happens in week two with hard evidence on the table.
And how the Syntra ETL platform addresses each one — before they consume your timeline.
WFC Pay Rules don't translate 1:1 to Fusion Time Categories. Discovery crawls every Pay Rule, Work Rule, Holiday Rule and Combination Rule, classifies by business purpose, produces a Fusion equivalent design. 25–40% typically retired.
Hundreds of millions of punch rows for 7+ years of FLSA retention. REST API for current data, direct read-only SQL with rowversion watermarks for historical tail. Streamed in parallel, hash-signed Parquet output.
$5M+ accrual liability common. Extract balances, YTD earn/take, carryover and caps per accrual code. Fusion Absence Plan Balance load. Reconciled to the hundredth-of-an-hour for SOX sign-off.
FMLA, ADA and state PFL leave cases with intermittent fragments and certifications. Case-state preserved through cutover so employees mid-leave don't restart the 12-week clock.
Kronos Private Cloud Dec 2025, on-prem Mar 2027. Project plan reverse-engineered from your specific EOL date with parallel-cutover gating, not a generic 12-month waterfall.
WFC Workforce Analytics doesn't carry over. Inventory, classification, Fusion OTBI / BI Publisher rebuild plan. 35–55% of reports retired during the cleanup as duplicates or low-value.
A repeatable, governed workflow built for WFC's particular complexity. Typical full-scope timeline: 10–14 weeks.
Discovery engine catalogs every Pay Rule, Work Rule, Holiday Rule, Combination Rule, Accrual Plan, Schedule Template, Workforce Analytics report and Function Access Profile in the WFC tenant via REST API plus direct SQL. Output: complete customization inventory, punch-volume estimate, accrual liability snapshot, sized assessment with risk register.
Pay group and labor account crosswalks, pay-rule to Fusion Time Category routing, work-rule to Time Consumer Set design, accrual plan to Fusion Absence Plan mapping, schedule template translation. Reviewed and signed off by HR, payroll, operations and union representatives where applicable.
WFC REST extractors and direct-SQL extractors pull employees, punches, timecards, schedules, leave cases, accrual balances, audit history. Output staged as Parquet partitioned by fiscal year and pay group with hash-signed manifests. Punch volumes streamed in parallel respecting API rate limits.
Crosswalks applied, pay rules collapsed to Fusion Time Categories, FBDI Time Card and HDL Absence Plan Balance payloads generated, validated against Fusion 26x Time & Labor and Absence templates. Errors surfaced locally with row-level diagnostics.
HDL and FBDI submitted to Fusion ESS, monitored to completion, reconciled at row, sum and hash level. In parallel, critical OTBI and BI Publisher reports rebuilt and validated against WFC Workforce Analytics equivalents. Pay rule and absence plan configuration validated end-to-end.
1–2 pay cycles in parallel (WFC + Fusion), deltas captured and replayed, reconciled to the cent, sign-off pack issued. WFC tenant moves to read-only archive mode; new punches and absence requests flow to Fusion only. Kronos infra retirement begins.
No more bespoke REST clients or SQL scaffolding. Just configure scope, run, reconcile.
Punches (TIMESHEETITEM), signed timecards, edits, comments, approvals pulled via REST API for current periods and direct read-only SQL for historical tail. Full audit trail for FLSA substantiation.
Published and unpublished schedules, shift templates, open shifts, swap requests, coverage gaps, fatigue rules via Workforce Scheduler API. Re-asserted to Fusion Time & Labor for forward-looking schedule continuity.
Active balances per accrual code, YTD earnings/takings, carryover and cap context. Emitted as Fusion HCM Absence Plan Balance HDL load. Reconciled to the hundredth-of-an-hour.
FMLA, ADA, state PFL leave cases with intermittent fragments, certifications, eligibility from Workforce Absence Manager. Case state preserved through cutover, no clock restart for employees mid-leave.
Active and terminated employees, pay groups, labor account assignments, manager hierarchy, function access profiles. Aligned to Fusion HCM Worker model via HDL.
Every Pay Rule, Work Rule, Holiday Rule, Combination Rule, Wage Profile exported via Admin APIs — feeds the discovery-classification-rebuild loop without manual screenshots.
A typical Kronos Workforce Central to Oracle Fusion migration covering Time, Scheduling, Absence and 7+ years of punch and accrual history runs 10–14 weeks with Syntra ETL versus 7–11 months on consultant-led programmes. The acceleration comes from pre-built WFC API extractors (REST, plus direct SQL fallback for archived punch tables), governed crosswalks between WFC Pay Codes and Fusion HCM Element Entries, and a parallel-cutover playbook that respects the Kronos Private Cloud December 2025 EOL deadline. Customers staying on-prem with the March 2027 sunset still on the horizon usually run a 12-week project rather than the 14-week cloud-tenant retirement variant, but the kronos workforce central to oracle fusion migration playbook is identical.
Kronos Workforce Central is a legacy WFM suite — UKG (the Ultimate Kronos Group formed by the 2020 merger) has published end-of-life dates: Kronos Private Cloud December 2025, on-prem WFC March 2027. After those dates there is no Kronos product roadmap, no new releases and no compliance updates for state wage laws. The kronos workforce central to oracle fusion migration consolidates Time, Scheduling and Absence onto the same platform handling HR, Payroll and GL, kills a separate WFM subscription, removes a duplicated employee master, and lets you retire the dedicated Kronos infrastructure and database licences. Oracle Fusion Time & Labor now matches WFC on pay rule complexity, schedule generation, accrual processing and FLSA overtime, with embedded analytics that WFC requires Workforce Analytics for.
Syntra ETL supports the full WFC footprint. Workforce Timekeeper: punches (in/out, transfer, comment), edits, signed timecards, pay rules, work rules, holiday rules, comments and approvals. Workforce Scheduler: shift templates, schedules (published + unpublished), open shifts, swap requests, coverage gaps, fatigue rules. Workforce Absence Manager: leave cases (FMLA, ADA, state PFL), accruals (PTO, sick, vacation, comp time), eligibility, certifications, intermittent leave fragments. Workforce Activities, Attestation, Forecast Manager and Analytics are also extracted. All sourced via the WFC REST API where available, with direct read-only SQL against the WFC database for archived punch and accrual history that exceeds API retention windows.
Punch history is the largest data volume in any Kronos Workforce Central migration — hundreds of millions of punch rows are routine for a multi-thousand-employee deployment with 7+ years of FLSA retention. The WFC database (TKCS schema, primary tables TIMESHEETITEM, EMPLOYEE, ACCRUALBALANCE) holds the granular punch detail; the REST API surfaces it but with rate limits. Syntra ETL streams punches in parallel via API for current periods and uses direct read-only SQL with rowversion watermarks for historical tail extraction, partitions output as Parquet by fiscal year and pay group, and routes to either Fusion Time & Labor (current period replay) or to the long-term Kronos archive (FLSA 3-year, state wage law up to 7-year, IRS 4-year).
Pay rules and work rules don't translate 1:1 — WFC uses a proprietary rule language (the Pay Rule Editor with Function Access Profiles, Pay Code Distributions, Combination Rules and Wage Profiles), and Fusion Time & Labor uses a different model built around Time Categories, Time Consumer Sets and Time Repository rules. Syntra ETL inventories every active Pay Rule, Work Rule, Holiday Rule and Combination Rule in the source WFC tenant, classifies each by business purpose (FLSA overtime threshold, shift differential, holiday premium, meal-break deduction, on-call premium), and produces a Fusion Time & Labor equivalent design with full traceability. Customers typically find 25–40% of WFC pay rules are redundant under Fusion's native rule engine and get retired.
Workforce Analytics (built on Cognos for older WFC releases, Tableau-style dashboards for newer) doesn't carry over to Fusion. The Syntra ETL discovery engine inventories every Workforce Analytics report, dashboard and Genie view in production use, classifies by business value (labor variance, overtime heatmap, FMLA caseload, accrual liability, FLSA exception report), and proposes Fusion replacements: OTBI dashboards for ad-hoc WFM analytics, BI Publisher for pixel-perfect operational reports like FLSA audit packs and accrual liability reconciliation, and Workforce Compensation analytics for labor-cost ties to GL. Approximately 35–55% of legacy WFC reports are duplicates or low-value and get retired. Critical reports are rebuilt in Fusion before cutover.
Accrual balances (PTO, sick, vacation, comp time, jury duty, bereavement) carry significant liability — a mid-size deployment can have $5M+ on the books in earned-but-unused balances. Syntra ETL extracts every active employee's accrual balance per accrual code as of a defined effective date, plus the year-to-date earnings and takings, plus the carryover and accrual-cap context, and emits a Fusion HCM Absence Plan Balance load with full traceability. Reconciliation matches WFC accrual liability to Fusion accrual liability per accrual code, per pay group, to the hundredth-of-an-hour. The signed evidence pack goes to finance for SOX accrual-liability sign-off — no manual GL adjustments at cutover.
No. Syntra ETL's WFC extractors run as a read-only API client with scoped access to the REST endpoints, and any direct database access uses a read-only SQL login against a read replica where available. Extracts are throttled to respect WFC API rate limits (typically 60 calls/min per tenant) and the largest extracts (multi-year punch history) are scheduled to run during off-peak windows. No changes are required to the WFC tenant configuration, no Kronos admin downtime is needed, and live punching, scheduling, and absence tracking continues uninterrupted through the project — including through the cutover weekend when WFC moves to read-only mode and Fusion Time & Labor takes the first punch.
