Migration route

Workday to Oracle HCM Cloud Data Migration

Migrate workers, assignments, compensation from Workday HCM to Oracle Fusion HCM Cloud using a controlled process for extraction, mapping, transformation, validation, loading and reconciliation.

Typical data scope

Scope is agreed in discovery. On this route it usually covers:

Source-to-target mapping

A mapping workbook carries every field in scope from its Workday source through its transformation rule to the Oracle HCM Cloud 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.

How Oracle HCM Cloud accepts the data

Load order is part of the design, not an implementation detail.

1. 1HDL — HCM Data LoaderThe primary bulk mechanism. Pipe-delimited .dat files, one per business object, zipped and loaded through the Import and Load Data process.
2. 2Business object dependency orderJobs, grades, locations and departments, then positions, then person and assignment, then salary and payroll. HDL rejects a child object whose parent has not loaded.
3. 3GUIDs and source keysObjects are matched on source keys carried in the .dat file. Getting the source key strategy right is what makes a second load an update rather than a duplicate.
4. 4Effective dating is explicitEvery dated object carries its effective start and end. Overlaps and gaps are rejected, so date sequencing is validated before load.
5. 5Load, then review the process logImport and Load Data reports per-object success and failure with reason codes; failures are categorised, corrected in transformation and reloaded.
6. 6Payroll balances as a separate passBalance initialisation runs after core worker data, against the payroll definitions already in place.

Migration cycles

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.

1. 1Mock / PPR 1First full extract, transform, load, reconcile and exception analysis. Expect the largest correction list here.
2. 2Mock / PPR 2Corrections applied, re-extract, re-run. Intended to closely replicate the production migration.
3. 3Production cutoverFinal extract, data freeze, load, reconciliation, business validation and sign-off.
