Programme-level ukg pro + ready migration reconciliation across every checkpoint: post-extract, post-transform, post-load, parallel-payroll, post-cutover. Hash-signed manifest chain UKG → Parquet → HDL → Fusion. SOC 1-ready evidence at every gate.
Data validation at the HDL load is point-in-time. UKG Pro + Ready migration reconciliation is the programme-level discipline that runs source-vs-target comparisons at every checkpoint from initial extraction to twelve months post-cutover.
UKG (Ultimate Kronos Group, formed from the 2020 Ultimate Software + Kronos merger) operates two cloud HCM product lines: UKG Pro covering enterprise customers and UKG Ready covering SMB customers. Both carry years — often a decade — of operational payroll, benefits and workforce-management evidence. The IRS Pub 15 4-year retention, the ERISA 6-year retention, the FLSA + state wage law retention (California 8 years, NY 6 years, MA 3 years), the ACA Employer-Mandate retention, the I-9 retention under DHS rules and the EEO-1 4-year retention each survive the live UKG tenant. Migration reconciliation is the discipline that proves every retained record arrives in Oracle Fusion HCM (or in the long-term archive) intact, with full provenance from the original UKG record to the Oracle Fusion state.
Syntra ETL ships ukg pro + ready migration reconciliation as a programme-level deliverable, not as a post-load validation afterthought. Each checkpoint produces a signed reconciliation pack: post-extract pack signed by the extraction lead + HR Systems; post-transform pack signed by the conversion lead; post-load pack signed by Payroll Director + Benefits Director; parallel-payroll pack signed by Payroll Director + Compliance; post-cutover pack signed by internal audit after one full tax year cycle.
The hash-signed manifest chain — UKG source → Parquet staging → HDL .dat → Oracle Fusion HCM state — is the tamper-evident audit anchor that lets internal audit and external SOC 1 auditors walk the controls without separate evidence reconstruction. Public companies routinely accelerate the post-cutover SOC 1 Type II examination by 4–6 weeks because the ukg pro + ready migration reconciliation pack is accepted as testing population without separate sampling.

UKG Pro + Ready migration reconciliation is the operating framework that establishes a continuous source-of-truth comparison between the live UKG Pro / UKG Ready tenant and the Oracle Fusion HCM target across the entire migration window — not just at the moment of HDL load completion. Where data validation is point-in-time post-load verification, ukg pro + ready migration reconciliation is the programme-level discipline that runs source-vs-target comparisons at every checkpoint: post-extract reconciliation (UKG source row counts vs Parquet staging), post-transform reconciliation (Parquet staging vs HDL .dat file), post-load reconciliation (HDL .dat vs Oracle Fusion HCM state), parallel-payroll reconciliation (one full pay cycle UKG + Oracle Payroll cent-perfect), and post-cutover reconciliation (Oracle Fusion HCM continues producing matching W-2, 941, 940, 1095-C, EEO-1 outputs against the UKG historical baseline). Each checkpoint produces a signed reconciliation pack that flows into the SOC 1 Type II evidence trail.
The post-extract checkpoint of ukg pro + ready migration reconciliation runs immediately after the UKG Pro Web Services / UKG Ready API extraction completes. For each UKG domain — Worker, Position, Job, Grade, Organisation, Location, Pay Statement (with all line types), Timecard, Schedule, Accrual, Benefit Enrolment, Dependent, ACA 1095-C, Recruiting, Performance, Learning — the engine compares the UKG admin-reported source count against the extracted Parquet row count plus the hash-signed manifest. Any divergence triggers a re-extract for the missing range (typically rate-limit-induced or off-peak-window-induced gaps). The post-extract reconciliation pack is signed by the Syntra ETL extraction lead and the customer's HR Systems lead before any transformation begins. No transformation runs against an incomplete extract.
The post-transform checkpoint of ukg pro + ready migration reconciliation runs after the Syntra ETL conversion engine has produced the HDL .dat files from the staged Parquet output. The engine compares the Parquet row count against the HDL .dat line count for each business object (Worker.dat, WorkRelationship.dat, Assignment.dat, ElementEntry.dat, BalanceInitialization.dat, Absence.dat, Benefits.dat) and validates each .dat file against the Oracle Fusion HCM 26x schema. The transformation is also field-level reconciled: every UKG field bound to an Oracle field per the signed ukg pro + ready to oracle fusion data mapping must appear in the .dat output, with the expected value range. Records that fail the field-level reconciliation are captured pre-load with the exact field-level reason ready for bulk fix.
The parallel-payroll checkpoint is the most consequential gate in ukg pro + ready migration reconciliation. One full pay cycle is run in parallel — UKG Pro Payroll and Oracle Payroll both execute against the same worker population for the same pay period. The reconciliation engine then compares, per worker, every element bucket: gross pay, federal income tax, state income tax, FICA (employee + employer), Medicare (employee + employer + additional 0.9%), SUTA per state, local taxes per jurisdiction, supplemental wage tax, deductions (medical / dental / vision / life / disability / FSA / HSA / 401(k) / commuter / other), garnishments (with court-order substantiation), retirement contributions (employee + employer), other voluntary deductions and net pay. Cent-perfect parity per worker is required. Any divergence above $0.01 is flagged with source + target record ids for forensic walk-through.
Post-cutover reconciliation continues for one full year after Oracle Fusion HCM goes live and UKG moves to read-only archive mode. Each quarterly 941, each annual W-2, each annual 940, each state SUTA quarterly, each annual ACA 1094-C/1095-C, each EEO-1 filing produced from Oracle Fusion HCM is reconciled against the UKG historical baseline (the UKG values for the same period had it continued running). The ukg pro + ready migration reconciliation engine surfaces any divergence pattern that suggests a residual mapping issue or a missed tax-engine rule. By the end of the first full post-cutover year — which includes one complete tax year cycle — the regulatory continuity has been independently verified across IRS, DOL, ACA and EEO-1 dimensions.
Hash-signed manifests are the tamper-evident audit anchor across every ukg pro + ready migration reconciliation checkpoint. The extraction engine emits a SHA-256 hash-signed manifest covering the UKG tenant identifier, the Web Services / API endpoints called, the time window, row counts per domain, file hashes per Parquet output and per payroll-evidence PDF, the API user identity, OAuth scope and per-call timestamps. The transformation engine emits a downstream manifest binding the source Parquet hashes to the produced HDL .dat hashes. The load engine emits a manifest binding the HDL .dat hashes to the Oracle Fusion HCM post-load state. Internal audit and external SOC 1 auditors can independently verify the full chain — source UKG record → Parquet → HDL .dat → Oracle Fusion HCM state — without any reconstruction effort.
Late-arriving corrections are routine during a UKG cutover window — a manual W-2c, a missed garnishment update, a retroactive bonus, a late benefit enrolment, a corrected timecard punch. The ukg pro + ready migration reconciliation framework runs a daily delta extract against the UKG modified-since watermarks during the cutover window, identifies any corrections that have landed in UKG after the bulk extract, and routes them through the same transformation pipeline as deltas. Each delta is reconciled into the Oracle Fusion HCM target state with a chain-of-custody record (UKG correction id → Oracle Fusion correction id) preserved for audit. No correction goes uncaptured between the bulk extract and the cutover moment.
Public companies and regulated organisations carry SOC 1 Type II controls covering payroll accuracy, completeness and timeliness; HCM change management; access control; records retention. The ukg pro + ready migration reconciliation evidence pack is structured to feed directly into the SOC 1 Type II walk-through. Row-count reconciliation feeds payroll-completeness. Cent-perfect reconciliation feeds payroll-accuracy. Hash-signed manifest chain feeds the change-traceability control. HDL operator-id + timestamp log feeds access-control. Regulatory retention manifest feeds records-retention. Internal audit walks SOC 1 controls using the reconciliation pack as primary evidence. External SOC 1 auditors typically accept the Syntra ETL reconciliation pack as testing population without separate sampling — accelerating the post-cutover SOC 1 examination by 4–6 weeks.
