Migration route
PeopleSoft→WorkdayMigrate workers, job data, compensation from Oracle PeopleSoft to Workday HCM using a controlled process for extraction, mapping, transformation, validation, loading and reconciliation.
PeopleSoft to Workday is a cross-vendor HCM replacement between two systems that both model history properly — and model it differently. PeopleSoft keeps effective-dated, effective-sequenced rows; Workday reconstructs history through dated events processed by business processes.
That difference is the migration. The work is not moving fields, it is replaying a PeopleSoft history as a sequence of Workday events that produce the same end state.
Scope is agreed in discovery. On this route it usually covers:
Domain in scope for a typical PeopleSoft to Workday programme.

One controlled pipeline, run as repeatable cycles.
What the source platform makes available, and the constraints that shape the extraction design.
A mapping workbook carries every field in scope from its PeopleSoft source through its transformation rule to the Workday target object and field. It is reviewed and approved with the business before the production migration, and applied identically in every cycle so a decision made once is not re-made under cutover pressure.
The differences between PeopleSoft and Workday that create most of the work.
A PeopleSoft JOB row is a fact. In Workday the equivalent is a staged event — a hire, a transfer, a job change — with its own effective date and business process. The migration converts rows into an ordered event stream.
Concurrent jobs are separate PeopleSoft rows and must be expressed in Workday's own model for multiple positions rather than collapsed onto one worker.
Departments, jobs and locations scoped by SetID can mean different things in different business units, and flattening them merges structure that should stay separate.
Workday's organisational model is not a department tree. The PeopleSoft structure is re-expressed as supervisory organisations before any worker can be staged.
A load that ignores the configured process either fails validation or leaves events awaiting approval, which looks like missing data.
Load order is part of the design, not an implementation detail.
Treating a Workday load like an ERP insert is the single most common cause of a failed first cycle. Events, effective dating and the business process framework decide what a load actually does.
Mandatory fields, referential integrity, format checks, business-rule validation and duplicate detection run on the prepared data, so problems surface as reportable exceptions rather than as failed loads in Workday.
Source counts, transformed counts, rejected records and target counts, with control totals where the data supports them. Every discrepancy is categorised so the migration is approved on evidence rather than assertion.
The pipeline is run end to end more than once before anything touches production. A typical structure is a first rehearsal that surfaces the bulk of mapping and data-quality corrections, a second that applies them and demonstrates production readiness, and the production cutover itself. How many cycles a programme needs depends on data quality and scope, which is established during discovery.
Out-of-order events produce a worker whose current state is right and whose history is nonsense.
Bolt-ons hold data the business depends on and appear in no standard object list.
Accrual balances are employee-visible on day one and are reconciled explicitly.
