Overview
Moving from Workday HCM to Crelate is a scope-reduction migration, not a like-for-like platform swap. Workday HCM is an enterprise HRMS covering core HR, payroll, benefits, talent, absence management, and workforce planning across global jurisdictions. Crelate is an AI-powered ATS and recruiting CRM focused on candidate management, job orders, placements, and recruiting pipeline automation. The two systems share partial overlap in people records and organizational structure, but Crelate has no payroll, benefits, time-off, compensation planning, or learning management modules. We map Workers to Crelate People, Organizations to Companies, and Job Profiles to Skills and Requirements, then deliver an explicit written inventory of every Workday object with no Crelate equivalent so the customer's admin team understands exactly what is not migrating. Effective-dated history from Workday requires flattening or truncation since Crelate does not maintain temporal record semantics. Workflows, business processes, and automation rules from Workday do not migrate; we document them for admin rebuild in Crelate.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a Workday HCM object lands in Crelate, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Workday HCM
Worker
Crelate
Person
1:1Workday Workers (employees, contractors, contingent workers) map to Crelate People records. We extract the primary legal name, preferred name, contact information, and employment type. Worker's effective-dated job history (multiple job changes, promotions, transfers) requires flattening: only the current or most recent job assignment migrates as the active record in Crelate because Crelate does not maintain temporal employment history semantics. Historical job data that must be preserved is appended as a structured note block on the Person record.
Workday HCM
Organization (Cost Center, Business Unit, Region)
Crelate
Company
1:manyWorkday Organizations in a hierarchical graph (Supervisory Organizations, Cost Centers, Business Units, Regions) map to Crelate Companies. We collapse the multi-level org tree into a flat Crelate Company record, preserving the top-level and second-level org names as Company fields. If the customer requires org hierarchy visibility in Crelate, we create Crelate Companies for each Workday org node and link them via a self-referential Company relationship or a custom parent_company__c field. Cost center codes migrate as a custom text field on the Company record.
Workday HCM
Position
Crelate
Job Order
1:1Workday Positions (the organizational role boxes independent of the person holding them) map to Crelate Job Orders. Position title, working hours, and location migrate to the Job Order's title, employment type, and location fields. We exclude position-specific attributes that only make sense within Workday's position-based staffing model, such as supervisory or in-scope position relationships. Job Order status is set to match the position's active/inactive flag.
Workday HCM
Job Profile
Crelate
Skills / Requirements
lossyWorkday Job Profiles define the qualifications, skills, competencies, and experience required for a Position. We map profile attributes to Crelate Skills (as comma-separated text or Crelate's native skills taxonomy) and to the Job Order's requirements text block. Crelate does not have a structured competencies model, so profile sub-sections migrate as free-text formatted into the requirements field. Job Profiles without an active Position are not migrated as standalone records.
Workday HCM
Supervisory Organization
Crelate
Company (with hierarchy)
lossyWorkday Supervisory Organizations define manager-to-worker chains and reporting hierarchy. We extract the supervisor-worker relationship and map it to the Crelate Person record's reporting_to field by resolving the supervisor's Worker ID to the corresponding Crelate Person. If the supervisor is not a Crelate user, the reporting relationship is stored as a text field until the customer provisions the manager as a Crelate user.
Workday HCM
Compensation History
Crelate
Not supported
1:1Workday compensation entries (pay changes, bonuses, stock grants) are effective-dated and tied to a Worker. Crelate has no compensation module. We flag this object as out of scope and note it in the written migration inventory. If the customer requires placement compensation tracking, we map the most recent base salary as a static custom currency field on the Crelate Person record, with a clear field label indicating it is a snapshot rather than a history.
Workday HCM
Benefits Enrollment
Crelate
Not supported
1:1Workday Benefits Enrollment records (plan elections, coverage levels, dependents) have no Crelate equivalent. Crelate is a recruiting ATS, not an HRMS. We exclude this object from migration scope and document it in the written inventory. Organizations that need benefits data in Crelate must note that Crelate does not have a benefits schema; any such tracking requires a custom object with explicit field design.
Workday HCM
Time Off and Leave Balances
Crelate
Not supported
1:1Workday leave accruals, current balances, and pending absence requests are excluded from migration scope. Crelate has no absence management module. We document this in the written inventory with a recommendation that the customer's HR admin maintain absence tracking in a separate system or a Crelate custom object if the customer chooses to build one post-migration.
Workday HCM
Payroll Data
Crelate
Not supported
1:1Workday payroll summaries (gross pay, deductions, taxes, net pay, pay period registers) require payroll-specific API credentials and have no Crelate equivalent. Crelate stores placement fee and commission information on placements, not employee payroll. We exclude payroll data from the migration scope entirely and flag that payroll data migration requires a separate engagement with a payroll-focused data service.
Workday HCM
Custom Objects
Crelate
Custom Fields on Person or Company
1:1Workday Custom Objects extend the delivered Worker and Position schema with tenant-specific fields. Crelate supports custom fields (Text, Number, Money, Date, and other types) on Person and Company records. We discover every Workday Custom Object via WQL API or tenant report schema before migration, map each custom field to a Crelate custom field of equivalent type, and pre-create the destination fields before data load. Custom Objects with complex multi-level relationships that cannot be represented as flat fields on a Crelate record are documented as requiring post-migration admin review.
Workday HCM
Documents (attachments)
Crelate
File attachments on Person
1:1Workday Worker documents (offer letters, contracts, performance reviews) attach as binary blobs to the Worker record. Crelate supports file attachments on Person records. We export each document with its original filename, MIME type, and document category, then attach it to the corresponding Crelate Person record. Document category labels migrate as a Crelate custom field (document_type__c) for filtering. Large document archives exceeding 1 GB total require pre-scoping for export and upload timing.
Workday HCM
Candidate Application (Workday Recruiting)
Crelate
Candidate and Job Order pipeline
1:1If the customer uses Workday Recruiting, candidate applications and requisitions map to Crelate Candidates and Job Orders. Application status (applied, screening, interview, offer, hired, rejected) maps to the corresponding Crelate pipeline stage. Workday requisition approval chains do not migrate; we document them for the customer's admin to rebuild in Crelate's workflow automation.

Workday HCM gotchas
Effective-dated data requires sequential loading
Custom Objects are tenant-locked and require schema discovery
No public Workday API rate limit documentation
Historical payroll data export requires payroll-specific permissions
Crelate gotchas
120 req/min API rate limit throttles bulk migrations
20 custom field per-entity cap forces data model decisions
15,000-record export ceiling on single operations
Sequences and automation workflows do not migrate
API key is a querystring parameter, not a header
Pair-specific challenges
Migration approach
Discovery and scope definition
We audit the Workday tenant across modules in use (Core HR, Recruiting, Payroll, Benefits, Absence, Talent, Learning), count Worker records by type (employee, contractor, contingent), and run WQL queries to discover all Custom Objects and their field definitions. We pair this with a Crelate tenant review to confirm available custom field quotas and existing Job Order, Company, and Person record counts. The discovery output is a written migration scope that explicitly lists every Workday object being migrated, every object being excluded (payroll, benefits, time off, learning), and the reason for each exclusion. The customer signs off on scope before extraction begins.
Schema design and field mapping
We design the Crelate schema to receive the Workday data. This includes pre-creating custom Person fields for any Workday Custom Object attributes that map to Crelate fields, pre-creating Company records for each Workday Organization in the hierarchy, and configuring Job Orders to match the active Workday Position structure. We map Workday field types to Crelate field types, flagging any type mismatches (Workday multi-select picklist, for example, requires either a multi-select or comma-separated text field in Crelate). Schema design is validated in Crelate's test environment before production migration.
Sandbox migration and reconciliation
We run a full migration into Crelate's sandbox or a test environment using production-equivalent data volume. The customer's recruiting lead and HR admin reconcile record counts, spot-check 25-50 Worker-to-Person mappings against the Workday source, and verify that organizational hierarchy flattened into Companies reflects the actual reporting structure. Any field mapping corrections, custom field additions, or scope adjustments happen in this phase. No production data moves until sandbox sign-off is received.
Effective-dated history treatment
We apply the flattening rule to all effective-dated Workday records. For each Worker, we extract the most recent job assignment, compensation record, and organizational assignment by effective date, store these as current-state fields in Crelate, and append a formatted history block as a note attachment. The history block contains role titles, org assignments, and compensation values with their original effective dates in a readable table. The customer chooses whether historical records spanning more than one year are included or whether only the most recent 12-18 months migrate.
Production migration in dependency order
We run production migration in record-dependency order: Companies (from Workday Organizations, established first so that Person records have a Company lookup), Persons (from Workers, with flattened job data and history note), Job Orders (from Positions), Skills (from Job Profile attributes mapped to Crelate's skills taxonomy), and file attachments (Documents attached to each Person). Custom Object fields are loaded last as part of the Person migration batch. Each phase emits a row-count reconciliation report before the next phase begins.
Cutover, validation, and automation handoff
We freeze Workday write access during the cutover window, run a final delta migration of any records modified during the window, then designate Crelate as the system of record for recruiting data. We deliver the Business Process inventory document and the excluded-objects inventory (payroll, benefits, time off, learning) to the customer's admin team. We support a one-week hypercare window for reconciliation issues. We do not rebuild Workday Business Processes as Crelate recruiting automations inside the migration scope; that is documented for admin rebuild or a separate automation engagement.
