Overview
Moving from Workday HCM to BambooHR is a structural migration from a position-based, effective-dated enterprise HRMS to a job-based, employee-centric SMB HRIS. Workday models organizational staffing as Positions (vacancy slots independent of the person filling them) with supervisory hierarchies and effective-dated compensation and job-data changes. BambooHR uses a simpler job-based model where the Employee record holds the current job title, department, and manager without an intermediate Position object. We resolve that model gap during scoping, split multi-incumbent positions into individual employee records with their correct hire-date context, and preserve historical compensation and benefits enrollment data in BambooHR's Employee Files and custom field blocks. We do not migrate Workday Payroll Registers, Advanced Compensation Plans, or Absence Management configurations; these are flagged for the customer's HRIS admin to configure post-migration or to evaluate BambooHR's integrated payroll partner ecosystem.

Object mapping
Each row shows how a Workday HCM object lands in BambooHR, 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
BambooHR
Employee
1:1Workday Workers (employees, contractors, contingent workers) map to BambooHR Employees. The Workday Worker record contains personal data, employment terms, supervisory organization, job profile, and compensation all in one object; we split these into BambooHR's Employee profile fields (personal info), Job Info tab (title, department, manager, hire date), and Compensation block (pay rate, frequency). The Workday hire_date becomes BambooHR's hire date. Terminated workers map with their termination_date preserved.
Workday HCM
Position
BambooHR
Job Info (title + department)
1:manyWorkday Positions represent organizational staffing slots that may be filled, vacant, or held by multiple workers over time. BambooHR has no Position object; job title, department, and manager attach directly to the Employee record. We handle the split by mapping the primary incumbent's Position title and supervisory organization to the Employee's Job Info block. For positions held by multiple workers (same job, same org), we create one BambooHR Employee record per incumbent. Vacant positions do not have a migration equivalent in BambooHR and are flagged as excluded from scope.
Workday HCM
Supervisory Organization
BambooHR
Reporting Structure
1:1Workday Supervisory Organizations define the manager-to-worker reporting chain and can nest multiple levels deep. BambooHR represents hierarchy through the manager field on each Employee record. We extract the full supervisory org tree from Workday via the Organizations WQL query, map each manager's Worker ID to the corresponding BambooHR Employee manager_id lookup, and set the top-level manager's manager_id to null. Matrix reporting relationships (dotted-line) are noted as unsupported in BambooHR and excluded from scope.
Workday HCM
Organizations (Cost Centers, Business Units, Regions)
BambooHR
Departments
lossyWorkday Organizations form a hierarchical graph (cost centers, business units, regions) that maps to BambooHR's flat department list. We extract the full org hierarchy and flatten it into BambooHR departments, preserving department names and, where supported, the top-level parent organization. Sub-department nesting beyond two levels is collapsed into the closest BambooHR-supported hierarchy. The customer selects a naming convention during scoping.
Workday HCM
Compensation History
BambooHR
Employee Files (custom field block)
1:1Workday compensation entries (pay changes, bonuses, stock grants) carry effective dates and are effective-dated compensation entries tied to a Worker. BambooHR stores only the current pay rate in the Compensation block. We export each compensation event with its effective date, type (base salary, bonus, equity), amount, currency, and change reason, then map these to a structured Employee File attachment named 'Compensation History.pdf' or a custom field set if the customer prefers tabular data. We sequence compensation events chronologically during export so retroactive adjustments land in the correct order.
Workday HCM
Benefits Enrollment
BambooHR
Benefits (plan mapping)
lossyWorkday benefit elections (health, dental, vision, life, 401k) store plan names, coverage tiers, and dependent relationships with enrollment dates. BambooHR's Benefits module supports health, dental, vision, life, and supplemental plans with coverage levels (employee, employee+spouse, family). We map Workday benefit plan types to BambooHR plan categories, and Workday coverage levels to BambooHR coverage options. Where BambooHR does not support a specific benefit type (e.g., FSA, HSA, commuter benefits), we document the gap and recommend a manual enrollment review post-migration.
Workday HCM
Time Off and Leave Balances
BambooHR
Time Off
1:1Workday leave accruals, balances, and pending requests are tied to Worker and Plan combinations with accrual rates, carryover rules, and pending approvals. BambooHR Time Off supports accrual-based and unlimited plans with configurable policies. We export current accrual balances per Worker per Plan and import them as BambooHR time-off balances. Pending requests are recreated as BambooHR pending requests with the original request dates and hours. BambooHR's plan types (Annual, Accrual, etc.) are mapped from Workday plan configurations during scoping.
Workday HCM
Job Profiles and Skills
BambooHR
Jobs (job description)
1:1Workday Job Profiles define qualifications, skills, and competencies associated with a Position. BambooHR's Jobs module holds job title, department, employment status, and an optional job description. We extract Workday profile attributes (required skills, education, experience) and append them as structured text to the BambooHR job description field. Competency ratings and skills taxonomies that cannot fit in the job description are noted as unsupported and documented for manual follow-up.
Workday HCM
Custom Objects
BambooHR
Custom Fields
lossyWorkday Custom Objects extend the delivered schema and are tied to business objects like Worker or Position. BambooHR supports custom fields on Employee and a limited set of other objects. We discover every Workday Custom Object via WQL schema queries before migration, then create equivalent BambooHR custom fields (text, number, date, dropdown, checkbox) during the destination schema build. Any Custom Object field that cannot map to a supported BambooHR field type is flagged with the customer for a manual alternative (Employee File attachment or external record).
Workday HCM
Documents (Worker Attachments)
BambooHR
Employee Files
1:1Workday Worker documents (offers, contracts, performance reviews, I-9s) are stored as binary attachments with document category metadata. BambooHR Employee Files support file uploads per employee with category tagging. We export each document as a binary blob, map the Workday document category to a BambooHR file category (Offer Letter, Employment Contract, Performance Review, Onboarding), and upload to the corresponding BambooHR Employee Files section. Large document stores require storage estimation before migration to confirm the destination tenant has adequate capacity.
Workday HCM
Payroll Data
BambooHR
Flagged as excluded
1:1Workday payroll registers (gross pay, deductions, taxes, net pay, direct deposit) are gated by the Payroll system role and exported via payroll-specific APIs. BambooHR does not include native payroll at its Core tier and uses integrations with ADP, Gusto, or Paychex for payroll processing. We scope payroll summary export as a structured record block only if the customer has payroll-reader API access and a destination payroll integration already configured. Otherwise, payroll data is excluded from migration scope and flagged as a pre-requisite for post-migration setup.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
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
BambooHR gotchas
Undocumented API rate limits can trigger 503 errors
Per-employee pricing model requires active record count verification
API credentials must be sent on every request to avoid extra round trips
Custom field schema varies per account and requires manual inventory
Document and attachment exports are not covered by standard report exports
Pair-specific challenges
Migration approach
Discovery and scope definition
We audit the source Workday tenant across modules in scope (Core HCM, Compensation, Benefits, Time Off, Documents), custom object inventory via WQL schema queries, supervisory org depth, effective-dated record volume, and document attachment count. We pair this with a BambooHR plan assessment: Core ($6/employee/month) covers employee database, time off, and document storage; Advantage adds performance management and analytics. The discovery output is a written migration scope, a Custom Object field inventory, and a position-to-employee mapping design. We verify payroll-reader API access during this phase.
Schema build and position split design
We design the destination BambooHR schema: Employee custom fields (created per discovered Workday Custom Object), department list (derived from Workday Organizations), job records (derived from Workday Job Profiles), and time-off plan configurations. We define the position-to-employee split rule: for each Workday Position with one incumbent, we create one BambooHR Employee with the Position's title and department; for positions with multiple incumbents, we create one Employee per incumbent; for vacant positions, we document as excluded. BambooHR custom fields are created before any employee data import. Schema build is validated in a BambooHR demo or sandbox environment before production migration.
Sandbox migration and reconciliation
We run a full migration into the production BambooHR tenant using a representative data set (active employees, 3 months of history, sample documents). The customer's HRIS admin reconciles record counts (Employees in, Departments in, Time Off balances in), spot-checks 25-50 random employee records against the Workday source, and reviews custom field values for accuracy. Any mapping corrections (field type mismatches, dropdown value gaps, document category errors) are addressed here before the full production migration. This step also validates that BambooHR storage capacity covers the document volume.
Effective-dated record sequencing and compensation export
We export all effective-dated Workday records (Workers, Compensation, Benefits) sorted by effective date in ascending order. For each Worker, the latest effective-dated row becomes the BambooHR current state. All prior effective-dated rows are written to a Compensation History structured document per employee. We validate that retroactive compensation changes do not overwrite later effective values during the chronological export. The compensation export includes pay rate, frequency, currency, bonus amounts, equity grants, and change reason. The customer reviews the Compensation History format before finalizing.
Production migration in dependency order
We run production migration in record-dependency order: Departments and Jobs (foundational), Employees (with Job Info resolved), Time Off balances (linked to Employee), Benefits enrollments (linked to Employee), Custom Object fields (linked to Employee), Document attachments (linked to Employee Files). Each phase emits a row-count reconciliation report before the next phase begins. Owner and manager lookups are resolved via Workday supervisor references mapped to BambooHR manager fields. Any Workday Worker without a resolved BambooHR manager reference is placed in a reconciliation queue for the customer's HRIS admin to resolve before record finalization.
Cutover, validation, and workflow rebuild handoff
We freeze Workday writes during cutover, run a final delta migration of any records modified during the migration window, then set BambooHR as the system of record. We deliver a written Workflow and Business Task inventory document to the customer's HRIS admin: Workday business tasks, approval chains, and absence management configurations are not migrated as code. We provide a recommended BambooHR替代配置指南 for each business process. We support a one-week hypercare window for reconciliation issues. We do not configure BambooHR payroll integrations, benefits broker connections, or time-tracking device integrations as part of the standard migration scope; these are separate setup engagements.
