Migrate from Workday HCM to Bullhorn ATS & CRM

Workday Workers encompass employees, contractors, and contingent workers under a single record type. Bullhorn separates external candidates (Candidates), placed contractors (Candidate with placement records), and internal staff (Employee/Contact). We split on Workday's Worker Type: regular employees migrate to Bullhorn Employee or Contact records; contingent workers and contractors migrate to Candidate records with their employment-type flag preserved. Supervisory hierarchy from Workday maps to Bullhorn's reporting structure on Employee records.

Workday Positions are organizational boxes defining a role independent of the person holding it, carrying effective-dated changes to job title, pay grade, and supervisory org. Bullhorn Jobs are requisitions or job orders representing open reqs. We map Workday Position attributes (title, job profile, pay grade, location) to Bullhorn Job fields. Multi-incumbent positions collapse into a single Job with headcount noted, because Bullhorn does not maintain a position-vs-incumbent separation.

Workday Supervisory Organizations define the manager-to-worker reporting chain and organizational hierarchy. Bullhorn Employee records have a ReportsTo field linking to another Employee record. We extract the supervisor-to-worker chain from Workday's supervisory org graph and map it to Bullhorn Employee ReportsTo. Bullhorn does not support a multi-level org chart as a native object; we document the full hierarchy as a reference table for the customer's admin to configure in Bullhorn's org structure if needed.

Workday Organizations form a hierarchical graph of cost centers, business units, and regions. Bullhorn represents organizational units as flat Departments (on Job and Placement records) or as Client Corporations (the CRM side). We flatten Workday's multi-level hierarchy into Bullhorn Department records, preserving the top-level organization and cost center as a parent reference where Bullhorn supports it. Regional and country-level org units that have no Bullhorn equivalent are mapped to custom fields on Job and Employee.

Workday Compensation entries are effective-dated records of pay changes, bonuses, and stock grants tied to a Worker. Bullhorn Candidate records carry a Bill Rate (for contractors) or a compensation block (for placed employees). We export each compensation event with its effective date, type, amount, and currency, and load the most recent effective-dated compensation as the current Bill Rate or Employee compensation in Bullhorn. The full compensation history is preserved as a structured JSON blob in a Bullhorn custom text field for audit purposes.

Workday Benefits Enrollment records contain plan elections, coverage tiers, and dependents tied to benefit plans. Bullhorn has no native benefits administration module. We map benefit plan types (medical, dental, vision, life, disability, 401k) and coverage levels to Bullhorn Candidate custom fields or a structured record block on the Employee object. Customers requiring full benefits administration post-migration should evaluate Bullhorn's HRIS add-ons or a third-party benefits platform integration.

Workday leave accruals, balances, and pending requests are tied to Worker and Plan combinations with effective-date semantics. Bullhorn does not natively manage time-off accruals. Current accrual balances and pending requests export as structured data and map to Bullhorn Candidate or Employee custom fields. Pending requests are documented as a reconciliation list for the customer's Bullhorn admin to action post-migration. Workday's accrual calculation rules do not migrate.

Workday Custom Objects extend business objects (Worker, Position, Organization) and are tenant-locked with no auto-mapping to Bullhorn. Bullhorn caps Custom Objects at 2 on ATS tier, 10 on Front Office Growth/Enterprise, each with a maximum of 55 fields across text, drop-down, checkbox, and picker types. We discover the full Workday custom object graph via WQL before migration, then rank Workday custom fields by business criticality against Bullhorn's field cap. Any Workday custom fields exceeding the Bullhorn limit are documented in a gap analysis for the customer to prioritize or route to a Bullhorn add-on.

Workday Job Profiles define qualifications, skills, and competencies associated with a Position. Bullhorn Job records have a Skills field and support custom picklists for competencies. We extract Workday profile attributes and map them to Bullhorn Skills (multi-select picklist) and custom fields on the Job object. Skills taxonomy alignment is reviewed during scoping; mismatches between Workday's skill taxonomy and Bullhorn's skill list require a mapping table or custom skill creation in Bullhorn before migration.

Worker documents (offers, contracts, performance reviews) are binary attachments stored against the Workday Worker object. We export documents as file blobs with their document category (offer letter, NDA, I-9, etc.) and attach them to the corresponding Bullhorn Candidate or Employee record via the Bullhorn REST API. Document metadata (category, upload date, author) migrates as custom fields on the attachment record. Bullhorn's attachment storage limits apply; large document libraries may require Bullhorn CRM storage add-ons.

Workday payroll summaries (gross pay, deductions, taxes, net pay) are available via payroll reporting APIs but require payroll-reader role access. Bullhorn is not a payroll platform and does not maintain payroll registers. We export current-year payroll summaries as a structured record set for audit and tax compliance purposes and deliver them as a CSV alongside the migration, not as Bullhorn records. Any historical payroll data exceeding the current tax year is excluded from standard migration scope.

Workday Job Requisitions (effective-dated reqs tied to a Position with hiring timeline, compensation range, and location) map to Bullhorn Job records. Requisition status, job title, location, and job profile migrate directly. Workday req workflow states (draft, submitted, approved, open) map to Bullhorn Job status values. Interview schedules and scorecards from Workday Recruiting do not migrate; we deliver a written inventory for the customer's Bullhorn admin to configure Bullhorn's native interview and scorecard tools.
