Enterprise migrations routinely run months behind schedule. Yours doesn't have to.
This guide is for VPs of IT, data architects, and migration leads at companies moving data from PeopleSoft to Workday — whether you're scoping, planning, or mid-program.
PeopleSoft stores HR data in effective-dated rows across PS_JOB (job data), PS_PERSONAL_DATA (personal info), PS_ADDRESSES (addresses), and PS_COMPENSATION (pay) tables. Workday uses a fundamentally different worker-centric model with business process-driven events. Settle translates PeopleSoft's row-level effective dating to Workday's event-based worker history automatically.

How Settle automates your PeopleSoft to Workday migration
Settle profiles PeopleSoft's effective-dated tables and reconstructs the event timeline for Workday — converting PS_JOB rows into Workday staffing events (hires, transfers, promotions, terminations) with correct sequencing.
Department trees are mapped to Workday supervisory organizations with reporting line validation and setID-to-org scope translation.
Compensation data across PS_COMPENSATION rate codes is mapped to Workday compensation plans and earnings codes — with pay calculation validation against PeopleSoft's payroll results.
Settle catalogs all PeopleCode customizations, component interfaces, and application engine programs — generating a dependency report for Workday rebuild planning.

Common challenges migrating from PeopleSoft to Workday
Effective-dated rows to Workday events
PeopleSoft stores every change as a new effective-dated row with a sequence number. A single employee's job history might have 50+ rows in PS_JOB spanning years of promotions, transfers, pay changes, and organizational moves. Each row must be analyzed and converted to the appropriate Workday business process event — hire, job change, compensation change, transfer, or termination.

PeopleSoft uses department trees with setIDs and effective-dated org structures. Workday uses supervisory organizations with a different hierarchy model. The org structure mapping affects reporting lines, security, and business process routing — and PeopleSoft's tree-based model doesn't translate directly to Workday's supervisory org pattern.
Explore related migrations →Compensation and benefits complexity
PeopleSoft's compensation uses rate codes, compensation packages, and salary grades with effective-dated changes. Benefits use plan types, benefit programs, and event rules. Workday uses compensation plans, compensation packages, and benefit elections with different structural patterns. The mapping must preserve pay accuracy for the first Workday payroll run.
Explore related migrations →PeopleCode customizations
Most PeopleSoft installations have extensive PeopleCode customizations — record-level PeopleCode, component PeopleCode, application packages, and application engine programs. These contain business logic that must be documented for Workday rebuild. Settle catalogs all custom objects and their field dependencies.

The cost of manual PeopleSoft to Workday migration
PeopleSoft to Workday is the second-largest HCM migration corridor after SAP HR-to-Workday. Companies migrate because PeopleSoft's on-premise architecture is aging, Oracle's support and development investment has shifted to Oracle Cloud HCM, and Workday offers a modern cloud-native platform with superior employee experience and analytics. This migration is common among higher education institutions, government agencies, and mid-to-large enterprises that adopted PeopleSoft in the 2000s.
PeopleSoft uses an effective-dated row model — every change to an employee record creates a new row with effective date and sequence number in tables like PS_JOB, PS_COMPENSATION, and PS_PERSONAL_DATA. Workday uses a worker record with event-driven business processes. The structural translation from PeopleSoft's row-per-change model to Workday's event-based model is the core technical challenge. PeopleCode customizations, component interfaces, and application engine programs contain business logic that must be documented for Workday rebuild.
These migrations are typically managed by HR consulting firms over 12–18 months. PeopleSoft's effective-dated complexity, extensive customization at most organizations, and the volume of historical data make the conversion workstream particularly demanding.
Consulting-led delivery for migrations in this class typically runs $1.5M+. Settle prices it fixed and scoped — read the full cost breakdown.
