    The engagement

    An Ireland-based enterprise was moving its HR and payroll operation off Oracle PeopleSoft onto Oracle Fusion HCM Cloud. The program ran on a joint governance and execution model, and Syntra ETL provided the automated migration engine that did the heavy lifting — extraction, transformation and load.

    🧭

    Mastek — program lead

    Overall program management: planning, reporting, risk and dependency management, executive communications, and the primary interface to the end customer.

    🧩

    Excelencia — delivery partner

    Technical architecture and end-to-end delivery execution — data migration, integrations and technical sign-off — aligned to Mastek’s program plan.

    ⚙️

    Syntra ETL — migration engine

    The platform behind extraction from PeopleSoft, HDL transformation and load into Oracle Fusion, with reconciliation and delta runs built in.

    Why the Syntra ETL platform

    🤖

    Automated PeopleSoft extraction

    A PeopleSoft Application Engine program (with PeopleCode enhancements) orchestrates extraction from core tables — no manual data pulls, with run-control safety checks to prevent parallel runs.

    🔁

    Full, Change & delta runs

    Full and Change (delta) modes using a last-run timestamp, plus effective-dated logic for current employee records, so re-extracts pick up only what changed.

    📄

    HDL-compliant output

    Extraction and transformation produce Oracle HCM Data Loader (HDL) files (CSV/TXT) that conform to Oracle Fusion Cloud specifications.

    🇮🇪

    Compliance-first transformation

    Transformation focuses on the fields that matter for Irish Revenue reporting and PRSI (Pay Related Social Insurance), bridging PeopleSoft data to the Fusion model.

    Reconciliation built in

    Record-count comparison between source and target, data-type and null checks, and an exception log — every cycle.

    ⏱️

    Accelerated, low-risk cutover

    Automation of extraction and HDL transformation cuts manual effort and error, across iterative migration cycles before production cutover.

    How it was delivered

    A three-phase approach, each phase producing measurable, auditable deliverables:

    1

    Phase 1 — Preparation & extraction

    Define scope and extraction parameters, configure PeopleSoft run controls, extract from core tables into staging, and run initial data verification.

    2

    Phase 2 — Transformation & loading

    Map PeopleSoft fields to the Oracle Fusion data model, apply HDL transformation rules, generate output files, and load into the staging/target environment.

    3

    Phase 3 — Validation & governance

    Validate integrity and statutory compliance, monitor error logs, document validation rules and exceptions, and manage post-migration data governance.

    Built for Irish statutory compliance

    Payroll and HR data for an Irish employer carries specific obligations. The migration was designed around them from extraction onward — not bolted on at the end.

    Irish Revenue
    Tax and reporting fields mapped and validated for Irish Revenue payroll reporting.
    PRSI
    Pay Related Social Insurance data carried through extraction, mapping and HDL transformation.
    GDPR & audit
    Documented validation rules, exception logs and resolutions for data-privacy compliance and audit readiness.

    Frequently asked questions

    Who delivered this PeopleSoft to Oracle Fusion migration?

    It was delivered on a joint model: Mastek as program-management lead and primary customer interface, Excelencia as technical and delivery partner, with the Syntra ETL platform as the automated migration engine. The end customer — an Ireland-based enterprise — retained business ownership and final acceptance.

    Which Oracle Fusion HCM modules were in scope?

    Core HR (demographics, job, position, organizational assignments), Absence (leave balances, accruals, events, approvals), and Payroll (earnings, deductions, taxes, plus terminated and retiree history).

    How is data loaded into Oracle Fusion HCM?

    Via the Oracle HCM Data Loader (HDL). Syntra extracts from PeopleSoft and transforms the data into HDL-compliant files that conform to Oracle Fusion Cloud specifications.

    How is Irish statutory compliance handled?

    Irish Revenue reporting fields and PRSI (Pay Related Social Insurance) data are mapped and validated through the pipeline, and validation rules and exceptions are documented for GDPR and audit readiness.

    How much historical payroll data was migrated?

    Up to six years of historical payroll records, including terminated-employee and retiree information, to meet statutory and business-continuity needs.
