Overview

What this migration involves

CATS is an applicant tracking system built around recruiting workflows, while BambooHR is a full HRIS that spans employee onboarding through performance management and payroll. Migrating between them means moving from an ATS data model to an HRIS data model: candidate records from CATS map to BambooHR Applicants and new-hire Employee records, Job Orders map to BambooHR Jobs, and CATS pipeline stages map to BambooHR Status values. CATS has no public real-time API for bulk export; we work around this by automating the built-in CSV export, parsing the resulting file, and pushing data into BambooHR via its REST API with batch chunking. Workflows, custom automation rules, and reporting snapshots do not migrate as code or data. We deliver a written workflow inventory so your admin rebuilds routing rules in BambooHR's automation layer.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

AI proposes the map; you confirm before any record moves.

Relationships preserved

Parent–child, lookups, and ownership stay linked.

Full activity history

Calls, emails, meetings — with original timestamps.

Attachments & notes

Documents, uploads, and inline notes move with the record.

Why teams make this switch

Two sides of the same decision

Leaving

CATS

What's pushing teams away

  • Aging interface — reviewers describe the platform as 'klunky' and note the last major UI upgrade was years ago with no public roadmap for refresh.
  • Reporting limitations — although reports have improved, the platform is 'semi-customizable' with limited templates, pushing data-heavy teams toward BI exports.
  • Email sync reliability — multiple reviewers report email sync works 'about 50% of the time', creating gaps in candidate communication history.
  • Scalability ceiling — the platform is widely flagged as unsuitable for large enterprises or high-volume recruiting teams; performance and workflow efficiency degrade at scale.
  • Inconsistent support experiences — a minority of reviewers report defensive responses or limited assistance on certain issues, contrasting with the generally positive support reputation.

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 CATS objects map to BambooHR

Each row shows how a CATS 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.

CATS

Candidate

maps to

BambooHR

Applicant and Employee

1:many
Fully supported

CATS Candidate records split into two BambooHR objects: the applicant record (for candidates still in the hiring pipeline) and the Employee record (for candidates who reached Hired status). We extract hire_date from the CATS candidate status change timestamp and use it as the BambooHR Employee hire_date field. Contact information (name, email, phone, address) migrates directly. Source attribution, tags, and custom fields transfer as applicant metadata. Candidates with Rejected status are preserved as archived Applicants with disposition notes from CATS' last pipeline stage.

CATS

Job Order

maps to

BambooHR

Job

1:1
Fully supported

CATS Job Orders map directly to BambooHR Jobs. The CATS job title, description, department, and location fields align with BambooHR Job fields. We map CATS pipeline stages to BambooHR job Status values (Open, Closed, On Hold, Draft). If CATS has multiple job pipelines, we use the CATS pipeline name as a BambooHR Job custom field rather than creating multiple job boards, since BambooHR uses a single job listing structure per department.

CATS

Pipeline Stage

maps to

BambooHR

Job Status

lossy
Fully supported

CATS pipeline stages (New, Screening, Interview, Offer, Hired, Rejected, and any custom stages) map to BambooHR job Status values. Each CATS stage gets a status assignment during migration. If BambooHR's default status set does not include a CATS stage name, we document it as a custom status requirement for the customer's admin to add in BambooHR settings before the job import runs.

CATS

Activity (calls, emails, notes, interviews)

maps to

BambooHR

Application Note and Event

1:1
Fully supported

CATS Activities linked to Candidates migrate to BambooHR Application Notes. Interview events with timestamps, interviewer names, and ratings migrate as Application Event records if BambooHR's ATS module supports them, or as structured Application Notes with a type flag. Activity timestamps preserve the original CATS creation date. Owner attribution migrates by resolving the CATS user email to the BambooHR Employee record of the recruiter or hiring manager.

CATS

Custom Field (Candidate and Job Order)

maps to

BambooHR

Custom Field

lossy
Fully supported

CATS custom fields on Candidates and Job Orders migrate to BambooHR custom fields on the corresponding object. Text, number, date, and dropdown field types map directly. Checkbox fields map to BambooHR's Yes/No field type. Multi-select dropdown in CATS maps to a text field in BambooHR with comma-separated values unless a multi-select configuration exists in the destination. We export the full custom field schema from CATS during discovery and create the matching fields in BambooHR before importing any data.

CATS

User / Hiring Team

maps to

BambooHR

Employee

1:1
Fully supported

CATS user accounts (name, email, role, department) map to BambooHR Employee records for active recruiters. We use email as the dedupe key. Inactive CATS users who have no applicant or activity attribution migrate as inactive BambooHR Employees or are excluded based on scope during discovery. Owner IDs on Candidate and Job Order records are resolved to Employee IDs in BambooHR during the import phase.

CATS

Department

maps to

BambooHR

Department

1:1
Fully supported

CATS Departments export as a flat list and map directly to BambooHR Departments. Department is a required reference for Job Orders in CATS, so we import Departments before Jobs to satisfy the foreign key. If CATS has nested department structures, we flatten them into BambooHR's single-level department model and add a parent_department custom field if hierarchical context is required.

CATS

Tag / Label

maps to

BambooHR

Tag

1:1
Fully supported

CATS free-text and pre-defined tags on Candidates migrate as Tags on the corresponding BambooHR Applicant. Tags export as comma-separated values from CATS and split into individual Tag records in BambooHR. If the customer's recruiting team uses tags for source tracking (LinkedIn, Referral, Job Board), we map them to BambooHR's Applicant Source field instead and preserve the original tag string in a custom field for audit.

CATS

Attachment (resume, cover letter)

maps to

BambooHR

Employee File

1:1
Fully supported

CATS file attachments on Candidates migrate as Employee Files in BambooHR. We pull the file binary via CATS export or API, preserve the original filename and MIME type, and upload to BambooHR linked to the corresponding Applicant or Employee record. Resume files map to BambooHR's designated resume field where available, or to a custom file field. Multiple attachments per candidate migrate as separate file records.

CATS

Source

maps to

BambooHR

Applicant Source

1:1
Fully supported

CATS Candidate Source field (LinkedIn, Referral, Job Board, etc.) maps directly to BambooHR's Applicant Source field on the Job Application. If CATS uses a source taxonomy that does not match BambooHR's built-in options, we document the mismatch and either map to the closest BambooHR default or add the source value as a custom field on the Application object.

Pair-specific challenges

  • CATS has no real-time bulk API

    CATS provides a built-in export tool that generates XLS or CSV files for Candidates and Job Orders, but there is no documented public REST API with bulk endpoints for automated record extraction. We work around this by triggering the export via CATS' interface, downloading the generated file programmatically, parsing the structure, and pushing records into BambooHR's REST API. If the customer has API access enabled on their CATS instance, we use direct API pulls where available, but batch export remains the most reliable path for full-record migration. Timeline extends by one to two weeks if CATS export generation requires manual intervention per batch.

  • CATS workflows do not migrate to BambooHR

    CATS workflow rules define record routing, email triggers, and status-change automations that are application configuration, not data. These do not export from CATS and have no direct equivalent in BambooHR's automation model. We document every active CATS workflow during discovery with its trigger conditions, actions, and recipients, and deliver a written workflow inventory so the customer's admin can rebuild routing rules in BambooHR's notification and onboarding automation layer. Without this step, candidate routing stops at cutover and HR admins lose automated status-change emails.

  • BambooHR's ATS is lighter than CATS' pipeline feature set

    BambooHR's applicant tracking covers the job posting, application, and hiring pipeline but does not match CATS' configurable pipeline stage depth. Multi-stage CATS pipelines with conditional routing, automated stage-to-owner assignment, and stage-specific email templates require rebuilding in BambooHR's more limited automation model. We flag every CATS pipeline stage with automation dependency during discovery and include it in the workflow handoff document. Teams with fewer than five pipeline stages and simple routing rules find BambooHR's standard status-based flow sufficient.

  • Attachment file size limits in BambooHR API

    BambooHR's API imposes limits on individual file upload size. Large resume files (PDFs over 10 MB) and bulk attachment uploads may require chunked upload handling or manual re-upload for individual records. We assess the attachment file size distribution during discovery. If more than 10 percent of CATS attachments exceed BambooHR's upload limit, we document the affected records and recommend either compressing files before upload or using BambooHR's file hosting separately with links stored in the custom fields.

  • Per-seat to per-employee pricing shift requires CATS seat audit post-migration

    CATS bills per active user seat. BambooHR bills per employee. After cutover, the customer must audit their CATS user roster and reduce seats to avoid paying for unused CATS licenses during any overlap period. We export the full CATS user list during migration scoping and flag any user without activity attribution in the past 90 days as a candidate for deactivation. Reducing CATS seats requires separate account management steps outside the migration scope and may have billing cycle implications depending on CATS contract terms.

Migration approach

Six steps for a successful CATS to BambooHR data migration

  1. Discovery and export assessment

    We audit the CATS instance for candidate volume, job order count, custom field schema, active pipeline stages, attachment file count and size distribution, and user roster. We assess whether the CATS instance has API access enabled and test the batch export tool's output format. We pair this with a BambooHR account audit to confirm ATS module availability, existing custom field configuration, and department structure. The discovery output is a written migration scope with record counts per object, a custom field mapping table, and an export method recommendation (API pull vs batch CSV).

  2. Custom field schema creation in BambooHR

    Before any data moves, we create the matching custom field schema in BambooHR. We create custom fields on Applicant and Employee objects for every CATS custom field that has no direct BambooHR equivalent. We add a CATS candidate ID custom field to preserve the source record reference. We configure job Status values to match the CATS pipeline stages, adding any non-standard stage names as custom status options in BambooHR settings. This step requires BambooHR admin credentials and runs in a staging window before production migration begins.

  3. CATS data export and parse

    We trigger the CATS batch export for Candidates and Job Orders, download the generated file, and parse it into a normalized intermediate format. We extract attachments separately via the CATS API or file export tool. We run a record count validation against the CATS UI totals and flag any discrepancy. If the export requires manual generation per batch (common in older CATS instances), we coordinate with the customer's CATS admin to run exports in sequence. The parsed output is a set of CSV files ready for BambooHR API ingestion.

  4. Owner and department reconciliation

    We extract every distinct CATS user referenced as an owner on Candidate, Activity, and Job Order records and match by email against the BambooHR Employee table. Any CATS user without a matching BambooHR Employee record goes to a reconciliation queue for the customer to provision before the import resumes. We also validate that all CATS Departments have a corresponding BambooHR Department; missing departments are created before Job Orders are imported so that the department reference is satisfied on insert.

  5. Production import in dependency order

    We run production import in record-dependency order: Departments first, then Employees (for active recruiters), then Jobs (with status mapped), then Applicants (with hire_date set for Hired candidates and source attribution preserved), then Application Notes and Events (with ActivityDate set to the original CATS timestamp), then Employee Files (attachments with original filenames preserved). Each phase emits a row-count reconciliation report before the next phase begins. We use BambooHR's REST API with batch endpoints and rate-limit handling for bulk inserts.

  6. Cutover, validation, and workflow handoff

    We freeze CATS writes during cutover, run a final delta migration of any records modified during the migration window, then mark BambooHR as the system of record. We validate a random sample of 25-50 applicant and employee records against the CATS source data and provide the customer with a full reconciliation report. We deliver the workflow inventory document to the customer's BambooHR admin team. We support a one-week hypercare window for reconciliation issues. We do not rebuild CATS workflows in BambooHR as part of the migration scope.

Most migrations land between four and six weeks for accounts with fewer than 5,000 candidate records, fewer than 500 job orders, and a straightforward custom field schema. Migrations with large attachment volumes (more than 10,000 resume files), complex multi-stage pipelines, or manual batch export requirements extend to eight to twelve weeks because of file re-upload time and pipeline stage reconciliation. BambooHR's own implementation documentation cites four to six weeks for initial setup, which aligns with our migration window when data is the primary scope.
