Overview

What this migration involves

Moving from Occupop to BambooHR is a platform-category shift from a dedicated ATS to an HRIS that bundles recruiting as a standard module. Occupop's data model is organized around Jobs and Candidates in pipeline stages; BambooHR's ATS organizes hiring around Job Openings and Job Applications attached to Employee records. We resolve this structural difference during scoping by mapping Occupop Jobs to BambooHR Job Openings (which require the ATS module at the appropriate tier), mapping Candidates to Applications, and resolving the stage-to-status mapping. Occupop's AI screening scores and board-distribution history do not have native equivalents in BambooHR; we preserve them as structured data attached to the application record. Custom fields from Occupop Candidate records map to BambooHR's Employee custom fields, subject to BambooHR's per-record field ceiling. We exclude offer letters, employment contracts, and onboarding workflow state, which Occupop hands to Cezanne HR post-acquisition and which are not accessible via the ATS export API.

Why teams make this switch

Two sides of the same decision

Leaving

Occupop logo

Occupop

What's pushing teams away

  • Advanced reporting and deep analytics lag behind enterprise HCM platforms, frustrating People teams that need custom dashboards or cross-pipeline trend analysis.
  • Occupop's feature set narrows as hiring needs scale beyond mid-market volume, pushing fast-growing companies toward platforms like Greenhouse, Lever, or Workday ATS.
  • Integration catalogue is smaller than competitors — teams with established HRIS, payroll, or background-check tools may face manual re-entry or custom integration work.
  • The acquisition by Cezanne HR (March 2025) introduces uncertainty about roadmap direction, pricing continuity, and long-term product independence, prompting some customers to evaluate alternatives proactively.

Choosing

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 Occupop objects map to BambooHR

Each row shows how a Occupop 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.

Occupop

Job

maps to

BambooHR

Job Opening

1:1
Fully supported

Occupop Jobs map directly to BambooHR Job Openings, which require the ATS module to be enabled on the customer's BambooHR tier (5 openings on Core, 25 on Pro, 50 on Elite). We export Job title, description, department, location, and status (active/closed). The BambooHR Job Opening is created first so that subsequent Candidate-to-Application mapping can reference it as the parent. The original Occupop Job ID is preserved in a custom field on the Job Opening for audit traceability.

Occupop

Candidate

maps to

BambooHR

Job Application

1:1
Fully supported

Occupop Candidates map to BambooHR Job Applications, which are linked to both a Job Opening and an Employee record. When the Candidate has no corresponding Employee in BambooHR yet (common for early-stage applicants), we create a minimal Employee record as a placeholder so that the Application has a valid parent. The Candidate's name, email, phone, and stage history migrate to the Application. If the BambooHR tier does not include the ATS module, Applications cannot be created; we flag this at scoping and confirm the customer's tier selection before migration.

Occupop

Workflow Stage

maps to

BambooHR

Application Status

lossy
Fully supported

Occupop Workflow Stages (Applied, Screening, Interview, Offer, etc.) per Job map to BambooHR Application Status values. We build a stage-name mapping table during scoping, preserving the stage order from Occupop. Not all Occupop stage types have BambooHR equivalents; where no match exists we map to the nearest BambooHR status (e.g., Offer stage maps to Hired, or a custom Rejected status for pipeline stages beyond the standard). The mapping is applied consistently across all Jobs at import time.

Occupop

User

maps to

BambooHR

Employee

1:1
Fully supported

Occupop Users (Hiring Managers, Recruiters, Admins) map to BambooHR Employee records. We export name, email, and role assignment. Role mapping is configuration-only in BambooHR; permissions live in BambooHR's permission system rather than named recruiter/hiring-manager roles. We map Occupop Admin to BambooHR Full Admin permission and Occupop Hiring Manager/Recruiter to BambooHR Standard User with recruiting-specific access granted via the ATS module permissions. Users who are purely ATS users with no corresponding employee record in the HRIS get a placeholder Employee record with the ATS permission flag set.

Occupop

CV and Attachment

maps to

BambooHR

File Attachment

1:1
Fully supported

Occupop CV file references and attachments map to BambooHR File Attachments linked to the Employee record or Job Application. We export raw CV files alongside the record mapping and deliver them as a file package. BambooHR's file attachment API supports PDF, DOC, and DOCX; we convert any non-standard format during export and flag any files that cannot be converted. The original file name is preserved in the BambooHR attachment record.

Occupop

Interview Feedback and Notes

maps to

BambooHR

Note

1:1
Mapping required

Occupop interview notes, scorecard responses, and written feedback per Candidate per stage migrate to BambooHR Notes linked to the Application or Employee record. We preserve the stage context by including the stage name in the Note title. Score values from scorecards migrate as structured text within the Note body; they do not populate a native numeric field in BambooHR since BambooHR does not have a native interview-scorecard object.

Occupop

AI Screening Score

maps to

BambooHR

Custom Field or Note

lossy
Fully supported

Occupop AI screening scores (0-100 values computed from CV-to-JD matching) do not have a native equivalent in BambooHR. We handle this by either creating a BambooHR Employee custom field of numeric type (if the customer's BambooHR plan supports custom fields and the field ceiling has not been reached) or by attaching a structured Note to the Application record containing the score value, rank within the candidate pool, and scoring rationale. The customer chooses the strategy at scoping. We flag that BambooHR's API has a documented per-record field ceiling that may limit the number of custom numeric fields on the Employee object.

Occupop

Custom Fields (Candidate)

maps to

BambooHR

Custom Fields (Employee)

1:1
Fully supported

Occupop's per-tenant custom key-value pairs on Candidate records map to BambooHR Employee custom fields. We inspect the source tenant's custom field definitions during scoping, build a field map, and apply it at import time. Field type mapping is direct for string, number, and date types. Occupop multi-select or tag-style custom fields map to BambooHR multiselect custom fields. We flag any custom fields that exceed the BambooHR API field ceiling (approximately 400 fields per Employee record) and fall back to storing them as structured JSON in a single text field or as attached notes for those records.

Occupop

Job Board Distribution History

maps to

BambooHR

Note (Post-Migration Reference)

1:1
Fully supported

Occupop tracks which job boards a Job was distributed to (Indeed, LinkedIn, Reed, Glassdoor, niche boards) and the posting date. BambooHR has no native board-distribution tracking field. We export this as a structured list per Job and attach it as a Note to the Job Opening. We deliver a board-distribution summary sheet post-migration listing each Job, its original distribution channels, and dates so that the customer's recruiting team can manually re-create postings in BambooHR's job board distribution UI or via each board's native posting tool.

Occupop

Offer and Onboarding Records

maps to

BambooHR

None

1:1
Not supported

Offer letters, employment contracts, and onboarding workflow state are not accessible via Occupop's ATS export. Post-acquisition these records live in Cezanne HR's broader suite, not in Occupop's ATS data model. We explicitly exclude offer and onboarding records from migration scope and direct the customer to export them from Cezanne HR directly before initiating the migration. If the customer does not have Cezanne HR access, we recommend they contact Occupop support to retrieve offer and onboarding data before the migration window closes.

Pair-specific challenges

  • BambooHR ATS module tier constrains migration scope

    BambooHR's ATS functionality (Job Openings and Job Applications) is bundled into the HRIS subscription but gated by job-opening limits per tier: 5 on Core ($10/employee/month), 25 on Pro ($17), and 50 on Elite ($25). Occupop customers with more than 50 active Jobs at migration time cannot migrate all Jobs to a single BambooHR account without requesting a custom enterprise tier. We confirm the customer's BambooHR tier during discovery and map the Job count to the appropriate tier. If the customer's pipeline volume exceeds the tier limit, we surface this as a tier-upgrade recommendation before migration begins and scope the Job migration to the tier's limit with the remainder flagged for manual archival or re-creation.

  • BambooHR API field ceiling limits custom field density

    BambooHR's API has a documented per-record field ceiling (approximately 400 fields per Employee record read via API) that engineers encounter when pulling full employee records or performing bulk imports. Occupop tenants with extensive custom field definitions (some define 30-50+ custom Candidate fields) risk hitting this ceiling during migration. We count the total distinct custom fields during discovery and, where the combined Employee plus Application custom field count approaches the ceiling, we consolidate non-critical fields into a single structured JSON text field and document the breakdown for the customer. This is a known BambooHR API constraint, not a migration tooling limitation.

  • Occupop post-Cezanne acquisition data access may change

    Occupop was acquired by Cezanne HR in March 2025. Contract terms, data residency, support SLAs, and API access policies may change during the acquisition integration period. We verify the customer's current contract status, renewal date, and any Cezanne HR umbrella agreements that now apply during discovery. Migration scoping must account for potential re-consent requirements under updated terms of service. We also verify that the Occupop API export endpoint remains accessible and has not been migrated to Cezanne HR's infrastructure, which could introduce new authentication requirements or rate limits before migration begins.

  • AI screening scores and board distribution have no native destination fields

    Occupop's AI screening scores (numeric 0-100 per Candidate) and board-distribution history (list of job boards per Job) have no direct equivalent fields in BambooHR's ATS module or Employee record. We preserve both as structured data attached to the Application record or as Notes on the Job Opening, but the customer should understand that BambooHR's native UI will not display these values in the standard candidate pipeline view. The customer chooses between structured Note storage and custom field storage (if the BambooHR plan and API field ceiling permit) at scoping.

Migration approach

Six steps for a successful Occupop to BambooHR data migration

  1. Discovery and tier confirmation

    We audit the source Occupop tenant across active and closed Jobs, total Candidates, User accounts with role assignments, custom field definitions, Workflow stage configurations, CV file count and format distribution, and AI screening score availability. We pair this with a BambooHR tier review: Core ($10/employee/month, 5 Job Openings) covers most migrations with fewer than 5 active hiring pipelines; Pro ($17) covers up to 25 openings; Elite ($25) covers up to 50. We confirm the customer's BambooHR tier, verify that the ATS module is enabled, and identify any tier-upgrade requirements before scoping proceeds.

  2. Schema design and field mapping

    We design the field mapping table during a dedicated mapping session. Occupop Candidate fields map to BambooHR Employee custom fields where native equivalents do not exist; Occupop Job fields map to BambooHR Job Opening fields; Occupop stage names map to BambooHR Application Status values via a name-matching table. AI screening scores and board-distribution history are flagged for structured-note or custom-field storage based on the customer's BambooHR plan. Custom field type mapping handles Occupop string, numeric, date, and multi-select types against BambooHR's supported custom field types. The mapping table is validated against a sample of 20-50 records from the source before full export begins.

  3. CV and attachment export

    We export all CV files from Occupop as a file package with filename mapping back to the source Candidate record ID. We verify file format compatibility with BambooHR's supported types (PDF, DOC, DOCX) and convert any unsupported formats (ODT, TXT, RTF) to PDF during export. The file package is delivered alongside the record CSV for bulk attachment during import. This step runs in parallel with the record export to reduce total migration time.

  4. Sandbox or pilot migration

    We run a pilot migration into the customer's BambooHR account using a subset of 50-100 records (10-20 Jobs and their associated Candidates) to validate the field mapping, verify Job Opening and Application creation, confirm permission and role mapping, and check CV attachment success. The customer's HR admin spot-checks 20-25 records against the source Occupop tenant and signs off the mapping before the full migration begins. Any field mapping corrections, stage name adjustments, or custom field type changes happen here.

  5. Full production migration in dependency order

    We run the full migration in record-dependency order: Job Openings first (as the parent for Applications), then Employees and Users (as the recipient for ATS User records), then Job Applications (with Job Opening and Employee references resolved), then Interview Notes and Feedback, then CV file attachments. AI screening scores land as custom fields or structured Notes depending on the chosen strategy. Board-distribution history is exported as a separate structured reference file attached to each Job Opening Note. Each phase emits a row-count reconciliation report before the next phase begins. We use BambooHR's API with rate-limit handling and exponential backoff for all inserts.

  6. Cutover, validation, and Cezanne HR data handoff

    We freeze Occupop writes during cutover, run a final delta migration of any records modified during the migration window, then confirm BambooHR as the system of record for all migrated data. We deliver the board-distribution reference sheet, the custom field consolidation summary (if any fields were stored as JSON due to API field ceiling), and the stage mapping legend. We exclude offer letters and onboarding records from the deliverable and remind the customer to retrieve these from Cezanne HR directly. We support a five-business-day post-cutover window for reconciliation issues raised by the recruiting team.

Strengths

  • Unlimited user seats regardless of plan, eliminating per-seat cost surprises for growing hiring teams.
  • AI screening scores and ranks candidates against job descriptions, reducing manual CV triage for high-volume roles.
  • 1-click multi-channel job posting consolidates distribution to Indeed, LinkedIn, Glassdoor, and niche boards in a single action.
  • Clean, centralized dashboard surfaces every step of each open role's pipeline without switching views.
  • 2-week free trial with no credit card lowers evaluation friction for SMB buyers.

Weaknesses

  • Reporting and analytics lack the depth needed by People teams accustomed to custom BI dashboards or cross-pipeline trend views.
  • Smaller integration catalogue than enterprise competitors; customers on niche HRIS or background-check tools may need custom workarounds.
  • Advanced features (custom workflows, advanced analytics, some API capabilities) are gated behind higher tiers or future roadmap items.
  • Post-acquisition roadmap uncertainty may concern customers who need long-term product stability guarantees.

Strengths

  • Single platform consolidating ATS, onboarding, HR records, payroll, and time-off reduces system sprawl for SMBs.
  • Fast implementation — BambooHR reports four to six weeks from kickoff to go-live for most customers.
  • Per-employee pricing with automatic volume discounts makes cost predictable as headcount grows.
  • Strong customer support reputation (Support Heroes) cited consistently across G2, Capterra, and direct testimonials.
  • Well-documented API with UTF-8 encoding, clear field types, and HTTPS-only access.

Weaknesses

  • Mobile application is significantly limited compared to the desktop experience, frustrating remote and field workers.
  • Companies above 150–200 employees frequently outgrow the platform's feature depth and customization surface.
  • Limited advanced reporting and analytics compared to enterprise HR platforms — custom report building is the ceiling.
  • PTO and profile customization are pain points — non-standard accrual policies and complex org structures require workarounds.
  • Document management and attachment handling lack the granularity of dedicated document-centric HR systems.

Most migrations land between three and five weeks for accounts under 2,000 total Candidates and 100 active Jobs with no complex custom field schemas. Migrations with extensive custom field definitions (30+ fields), high-volume candidate pools (over 5,000 records), AI score preservation as structured data, or multiple Workflow stage configurations move to eight to twelve weeks because of field-mapping design, CV format conversion, and stage-to-status reconciliation work. The BambooHR ATS module tier confirmation adds one to two days to discovery before migration scoping begins.
