Overview

What this migration involves

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.

Why teams make this switch

Two sides of the same decision

Leaving

Workday HCM logo

Workday HCM

What's pushing teams away

  • Implementation complexity and multi-year commitments mean organizations are effectively locked in — switching costs are high and migration projects routinely run over budget and timeline.
  • Steep learning curve and rigid out-of-box workflows frustrate power users and recruiters who need more configurability than the UI exposes.
  • Premium pricing ($100–$300/user/month) combined with hidden implementation costs makes Workday prohibitively expensive for mid-market organizations with simple HR needs.
  • Frequent unplanned downtime and maintenance windows disrupt payroll and HR operations, with some organizations reporting regular service interruptions.
  • Limited customization for highly specialized or legacy HR workflows forces organizations to work around the system rather than with it.

Choosing

BambooHR logo

BambooHR

What's pulling them in

  • Lowest friction entry point for SMBs moving off spreadsheets — intuitive interface means most teams are functional within days, not weeks.
  • Consolidation value: BambooHR merges ATS, onboarding, HR records, time-off, and payroll into a single pane of glass that employees never need to leave.
  • Volume discounts applied automatically by headcount, so pricing scales predictably as the company grows without renewal negotiations.
  • BambooHR reports most customers go live in four to six weeks, making it a realistic commitment for under-resourced HR teams.
  • Award-winning Support Heroes cited frequently in reviews — responsive human support after implementation is a differentiator.

Object mapping

How Workday HCM objects map to BambooHR

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

maps to

BambooHR

Employee

1:1
Fully supported

Workday 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

maps to

BambooHR

Job Info (title + department)

1:many
Fully supported

Workday 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

maps to

BambooHR

Reporting Structure

1:1
Fully supported

Workday 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)

maps to

BambooHR

Departments

lossy
Fully supported

Workday 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

maps to

BambooHR

Employee Files (custom field block)

1:1
Mapping required

Workday 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

maps to

BambooHR

Benefits (plan mapping)

lossy
Mapping required

Workday 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

maps to

BambooHR

Time Off

1:1
Mapping required

Workday 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

maps to

BambooHR

Jobs (job description)

1:1
Mapping required

Workday 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

maps to

BambooHR

Custom Fields

lossy
Mapping required

Workday 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)

maps to

BambooHR

Employee Files

1:1
Fully supported

Workday 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

maps to

BambooHR

Flagged as excluded

1:1
Mapping required

Workday 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.

Pair-specific challenges

  • Position-based to job-based model requires upfront design

    Workday Positions represent staffing slots that can be filled, vacant, or held by multiple workers over time. BambooHR has no Position object; the job title, department, and manager attach directly to each Employee record. If a Workday position is held by more than one employee (same job, same org, different incumbents), we create one BambooHR Employee per incumbent and use the position's title and department for both. Vacant positions have no migration equivalent. We resolve the position-to-employee mapping during scoping and flag any position with no incumbent before migration begins. Skipping this step results in missing employee records or orphaned job assignments.

  • Effective-dated history collapses to current state in BambooHR

    Workday stores every historical change to a Worker record (title changes, compensation revisions, org reassignments) as a separate effective-dated row, preserving the full point-in-time record. BambooHR's Employee record holds only the current value; historical changes are not stored as separate records. We sequence all effective-dated records chronologically during export and write the final effective value as the BambooHR current state. Historical events are preserved as a Compensation History document or structured Employee File attachment. If the customer requires point-in-time reporting, we recommend a data warehouse or a BambooHR-reported export strategy post-migration.

  • Workday Custom Objects require explicit field-level discovery

    Workday Custom Objects are tenant-defined and are not visible in standard API documentation. We discover the full custom object graph via Workday WQL queries before migration. Every Custom Object field must be individually mapped to a BambooHR custom field or flagged as unsupported. BambooHR supports a limited set of custom field types (text, number, date, dropdown, checkbox) and does not support multi-select picklists, rich text, or cross-object lookups. Any Workday Custom Object field that exceeds BambooHR's type support is documented as a gap and handled as an Employee File attachment or a manual process.

  • Payroll data access requires explicit role provisioning

    Workday payroll registers, tax withholdings, and direct deposit records are gated by the Payroll system role and related security groups. Standard HRIS reader roles may not have payroll data access. Before scoping payroll migration, we verify the API credentials have payroll-reader access or we request the customer provision a payroll-reader role. Without this, payroll summaries are excluded from the migration scope entirely. If the customer plans to use BambooHR's integrated payroll (ADP, Gusto, Paychex), the payroll data migration scope depends on the partner integration's data import capabilities.

  • Document attachment volume may exceed BambooHR storage limits

    Workday tenants with multi-year histories accumulate large volumes of Worker documents (contracts, performance reviews, I-9s, benefits elections) stored as binary attachments. BambooHR's storage limits depend on the plan tier. We estimate total document attachment volume during discovery and confirm the destination BambooHR tenant has adequate storage before beginning document migration. If storage is constrained, we prioritize active employee documents and flag terminated employee documents for post-migration manual upload or a phased approach.

Migration approach

Six steps for a successful Workday HCM to BambooHR data migration

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

Migrations under 500 employees with no Custom Objects land between three and five weeks. Migrations with Custom Objects, multi-level supervisory hierarchies, multi-year compensation histories, or large document attachment volumes move to eight to twelve weeks because of WQL schema discovery, Custom Object field-level mapping, effective-date sequencing, and document extraction overhead. The primary timeline driver is the discovery and schema design phase, not the data migration itself.
