Overview
Moving from Happy Hire to BambooHR is a transition from a purpose-built ATS into a unified HRIS that combines hiring, onboarding, employee records, time-off, and performance management in one platform. The structural shift is the core challenge: Happy Hire stores Candidates and Applications as separate objects tied to Job postings, while BambooHR expects new hires to exist as Employee records that can optionally carry ATS metadata from a linked job opening. We resolve this by converting Happy Hire Candidates into BambooHR Employee records and linking each to a BambooHR Job Requisition, preserving the application stage, scorecard outputs, and source attribution as custom fields on the Employee record. Because Happy Hire has no documented public API, we extract via structured CSV export or direct database access where available, clean and type-validate the data, then import through BambooHR's API with field-level mapping. Workflows, onboarding checklists, and scorecard templates do not migrate as code; we deliver a written inventory of every automation and workflow for the customer's admin to rebuild in BambooHR.

Object mapping
Each row shows how a Happy Hire 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.
Happy Hire
Candidate
BambooHR
Employee
1:1Happy Hire Candidate records map to BambooHR Employee records. The conversion includes first name, last name, email, phone, address, resume file URL, source attribution, and current application status. We preserve the original Happy Hire candidate ID and any sourcing channel (referral, job board, direct) as custom fields on the Employee record. Candidates with no active Application become Employee records with a custom hire_source__c field set to the original source value; candidates with an active Application link to the corresponding BambooHR Job Requisition.
Happy Hire
Application
BambooHR
Job Application / Custom Field
1:1Happy Hire Applications carry stage (applied, screening, interview, offer, hired, rejected), timestamps for each stage transition, and reviewer assignments. Since BambooHR does not have a standalone Application object separate from Employee, we embed the application history as a custom text field application_history__c on the Employee record, storing stage name, transition date, and reviewing user in JSON-serialized format. Active applications still in progress at migration time are flagged with a migration_status__c custom field set to pending_hire.
Happy Hire
Job
BambooHR
Job Requisition
1:1Happy Hire Jobs map to BambooHR Job Requisitions with job title, description, location, department, and employment status. Active and closed jobs migrate with their posting metadata. We check the job count against the destination BambooHR plan tier (5, 25, or 50 openings) and flag any over-limit jobs before migration so the customer can close or archive postings in Happy Hire before cutover. Custom job fields from Happy Hire map to BambooHR custom fields on the Job Requisition object.
Happy Hire
User
BambooHR
Employee (BambooHR Admin access)
1:1Happy Hire User accounts (name, email, role: Admin, Recruiter, Hiring Manager) map to BambooHR Employee records with access levels assigned to match Happy Hire role permissions. We preserve the role assignment in a custom field happyhire_role__c and note the recommended BambooHR access level for each user. Note: BambooHR does not have a separate non-employee user model; contractors or external recruiters who were Happy Hire Users must be created as Employee records or managed through BambooHR's external sharing settings.
Happy Hire
Employee Record
BambooHR
Employee (existing post-hire record)
1:1Happy Hire post-hire Employee records (start date, department, employment status, title) map to BambooHR Employee records using the same schema as the Candidate conversion. Custom employee properties from Happy Hire map to BambooHR custom fields on Employee, though Information field types and section headers must be noted as API-incompatible and flagged for manual re-entry post-migration.
Happy Hire
Onboarding Task
BambooHR
Onboarding Checklist
lossyHappy Hire onboarding workflows with named checklists and task assignments migrate as onboarding templates in BambooHR. We export task names, assignees, and completion statuses. BambooHR's onboarding checklist uses a task-level structure where each item has a name and optional assignee; nested subtasks in Happy Hire may flatten to top-level checklist items. We document the nesting structure in the migration notes for the customer's admin to reassemble in BambooHR's checklist builder.
Happy Hire
Interview Scorecard
BambooHR
Custom Field (Employee record)
lossyHappy Hire Interview Scorecard templates and completed evaluations are exported as structured data. Completed scorecard ratings and evaluator notes are stored as a custom text field scorecard_history__c on the associated Employee record, with evaluator name, interview stage, rating values, and free-text comments serialized. The scorecard template structure itself is documented separately as a configuration note for the customer's admin to rebuild in BambooHR's custom form builder or as a PDF attachment to the Employee record.
Happy Hire
Job Board Posting
BambooHR
Custom Field (Job Requisition)
1:1Happy Hire tracks which external job boards a job was posted to and the posting URL where available. This metadata migrates as a custom text field job_board_postings__c on the BambooHR Job Requisition, storing an array of board name and URL pairs. Board-level analytics (posting performance, applicant volume per board) do not migrate because BambooHR's ATS does not natively track board-level analytics; we document the original board URLs for the customer's reference.
Happy Hire
Candidate File Attachment
BambooHR
ContentDocument (Employee record)
1:1Resume files and attachments stored against Happy Hire Candidate records are exported as files and linked to the corresponding BambooHR Employee record via ContentDocument and ContentDocumentLink. File type, original filename, and upload date are preserved in the ContentVersion metadata. We flag any file attachments that exceed BambooHR's file size limits for manual upload during the post-migration review period.
Happy Hire
Custom Fields (all objects)
BambooHR
Custom Fields
lossyHappy Hire custom fields across Candidate, Application, Job, and Employee objects are mapped to BambooHR custom fields on the equivalent destination object. BambooHR supports text, number, date, dropdown, checkbox, and URL custom field types. Fields of type Information, Section Header, or Multiple-Select List cannot pass via BambooHR API; these are flagged during the data audit with a field-level impact note, and the customer decides whether to re-enter these values manually post-migration or convert to a supported field type.

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.
Happy Hire gotchas
Catalog category mismatch — not an HRMS
Per-use billing means no recurring data to migrate at scale
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 export scope audit
We request sample CSV exports from Happy Hire across all supported objects: Candidates, Applications, Jobs, Users, Employee Records, Onboarding Tasks, and Interview Scorecards. We audit the export scope for column coverage, binary attachment availability (resumes, scorecard PDFs), and full field names for every custom field. We also identify whether a direct database export is available as an alternative or supplement to CSV, which may provide richer data for application stage histories and scorecard outputs. The discovery output is a written export scope report listing every object, field, record count, and any data that cannot be extracted from Happy Hire.
BambooHR destination audit and plan tier check
We audit the customer's target BambooHR plan tier against the migration scope: job opening count (5/25/50 limit), existing custom field count, and ATS feature requirements. We document which Happy Hire custom fields map to BambooHR-supported field types (text, number, date, dropdown, checkbox, URL) and which cannot be passed via API (Information, Section Header, Multi-Select List). We also audit the existing BambooHR employee schema if a destination account already exists, to avoid field name conflicts during custom field creation.
Schema design and custom field creation
We design the destination schema in BambooHR. This includes creating custom fields on Employee (candidate history, source attribution, application stage) and Job Requisition (job board posting metadata, Happy Hire job ID). We deploy custom fields via the BambooHR API before any record import. We also configure the BambooHR Jobs module with the customer's department and location structure to match Happy Hire's org hierarchy. The schema is validated against a small sample import (10 records) before full migration begins.
Data cleaning and field mapping
We transform Happy Hire exports to match the BambooHR schema. This includes type conversion (date formats, phone number formatting), dedupe on email address (Employee dedupe key in BambooHR), and encoding the full application history and scorecard data as custom field values. Any Happy Hire custom fields that cannot map to a supported BambooHR field type are flagged with sample values for the customer to decide: convert to a supported type, drop, or re-enter manually. Owner assignment (Hiring Manager, Recruiter) maps to the BambooHR Employee record of the corresponding user.
Production migration in dependency order
We run the migration in this sequence: (1) BambooHR Job Requisitions from Happy Hire Jobs, (2) BambooHR Employee records from Happy Hire Candidates and Employee Records, (3) Application history and scorecard data embedded as custom fields on each Employee, (4) User access level mapping with Happy Hire role preserved as a custom field, (5) Onboarding task and checklist metadata as a configuration document for the customer's admin to rebuild in BambooHR's checklist builder. Each phase emits a row-count reconciliation report before the next phase begins. File attachments (resumes, scorecard PDFs) upload via BambooHR's file API in a parallel pass after Employee records are created.
Cutover, validation, and automation rebuild handoff
We freeze writes in Happy Hire during cutover and run a final delta migration for any records modified during the migration window. We validate record counts in BambooHR against the Happy Hire source, spot-check 25-50 Employee records for data accuracy (name, email, start date, application history field), and deliver the onboarding template and scorecard template documents to the customer's admin team for rebuild. We do not rebuild Happy Hire onboarding workflows as BambooHR onboarding checklists inside the migration scope; that is a separate configuration task for the customer's HR admin. We support a one-week hypercare window for reconciliation issues raised during initial BambooHR use.
