Overview

What this migration involves

Moving from Adapt to Bullhorn is a platform consolidation within the Bullhorn ecosystem. Adapt by Bullhorn (formerly Bond AdaptUX, acquired by Bullhorn in October 2019) served as a recruitment-specific ATS at a lower price tier, while Bullhorn's main platform delivers a broader recruitment CRM with native automation, larger integration marketplace (350+ partners), and more configurable data models. We resolve the critical migration challenge: Adapt has no publicly documented REST API, so we confirm API access with Adapt directly during discovery and fall back to structured CSV export where automated export is not available. Bullhorn uses a tiered custom object model (Growth/Enterprise gets 10 custom objects with 55 fields each; ATS Growth gets none) that constrains how we map Adapt's custom employee properties. We migrate Employees to Bullhorn Candidate records, Contacts to ClientContact records, Companies to ClientCorporation records, and flag any records exceeding the Bullhorn tier limit for admin resolution before production migration. Bullhorn's implementation timeline of two to six weeks is realistic for most Adapt migrations; we align our discovery, schema design, and data migration phases with Bullhorn's onboarding cadence.

Why teams make this switch

Two sides of the same decision

Leaving

Adapt logo

Adapt

What's pushing teams away

  • Frustration with limited contact and mailbox counts leads users to seek platforms with more generous data storage or unlimited contact models.
  • Low-quality lead data from the email-finding extension causes users to question data accuracy and switch to dedicated sales intelligence tools.
  • Reinstalling the software on a new computer is cumbersome, with users reporting that email tracking activation fails repeatedly and support is unhelpful.
  • The platform's support responsiveness is cited as a pain point, with users feeling abandoned when technical issues persist across reinstalls.

Choosing

Bullhorn ATS & CRM logo

Bullhorn ATS & CRM

What's pulling them in

  • Agencies choose Bullhorn because it combines ATS and CRM in one platform, eliminating the need to switch between separate tools for candidate management and client relationship tracking.
  • The resume parser extracts contact details, work history, and skills into structured, searchable candidate profiles automatically without manual data entry, reportedly driving 24% more placements per recruiter.
  • Bullhorn's placement and split-billing model natively supports contract staffing workflows, handling start/end dates, overtime rules, and multi-party pay/charge rates in a single record.
  • The platform offers extensive third-party integrations through its Recruitment Cloud Marketplace, connecting with back-office, onboarding, and payroll systems used by staffing agencies.
  • 72% of Bullhorn customers are teams with fewer than 10 users, and Bullhorn's implementation team handles setup and data migration for small agencies going live within weeks.

Object mapping

How Adapt objects map to Bullhorn ATS & CRM

Each row shows how a Adapt object lands in Bullhorn ATS & CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.

Typical mapping — final map is confirmed during the sample migration step.

Adapt

Employee

maps to

Bullhorn ATS & CRM

Candidate

1:1
Fully supported

Adapt Employees map to Bullhorn Candidate records. The employee's name, email, phone, job title, department, and hire date map to Bullhorn Candidate's name, email, phone, skills, category, and dateAdded fields. We resolve the hire date to candidateDateAvailable and use a custom field adapt_original_hire_date__c to preserve the full employment start date separately from the Bullhorn record creation timestamp. Custom employee properties from Adapt (e.g., emergency contact, benefit elections) map to Bullhorn Custom Object instances attached to the Candidate.

Adapt

Contact

maps to

Bullhorn ATS & CRM

ClientContact

1:1
Fully supported

Adapt Contact records map to Bullhorn ClientContact. The contact's name, email, phone, company association, and custom fields migrate 1:1 to Bullhorn ClientContact fields. The Adapt browser extension's enrichment metadata (email-find history, confidence scores) migrates as custom fields on the ClientContact record to preserve the data's provenance. We flag any contact records exceeding the target Bullhorn edition's contact storage limit before production migration.

Adapt

Company

maps to

Bullhorn ATS & CRM

ClientCorporation

1:1
Fully supported

Adapt Company records map to Bullhorn ClientCorporation. Company name, domain, industry, address, and phone migrate directly. The Adapt company's billing address and annual revenue properties map to Bullhorn ClientCorporation billingAddress and annualRevenue fields. Custom company properties require field-level transformation during migration; we map text, date, number, and picklist types to their Bullhorn equivalents and flag any multi-select picklist values that exceed Bullhorn's allowed value list length.

Adapt

Department

maps to

Bullhorn ATS & CRM

Category

1:1
Fully supported

Adapt Departments map to Bullhorn Category records. Bullhorn Category objects serve as the taxonomy for classifying Candidates (by skill set), JobOrders (by department), and Placements. We preserve the Adapt department hierarchy (parent and child departments) as a Category tree structure. If Adapt uses a flat department list, we create a single-level Category hierarchy in Bullhorn.

Adapt

Custom Employee Properties

maps to

Bullhorn ATS & CRM

Custom Object (Candidate-attached)

lossy
Mapping required

Adapt custom employee properties map to Bullhorn Custom Object instances attached to the Candidate record. Bullhorn Growth and Enterprise editions support up to 10 Custom Objects with 55 fields each per entity (Candidate, ClientContact, ClientCorporation). Bullhorn ATS edition supports 2 Custom Objects; ATS Growth supports none. We audit the Adapt custom property count during discovery and map to the appropriate Bullhorn edition's Custom Object limits. If the customer's Adapt plan uses more custom properties than the target Bullhorn edition supports, we flag the overflow fields for admin resolution before production migration.

Adapt

PTO Balance

maps to

Bullhorn ATS & CRM

Custom Object (Candidate-attached) or Note

1:1
Fully supported

Adapt PTO balances (current balance and accrual history) migrate to Bullhorn as a Candidate-attached Custom Object with accrual date, accrual type, and balance amount fields. Bullhorn's standard ATS objects do not have a native PTO accrual model, so we use a Custom Object to replicate the accrual structure. If the target Bullhorn edition does not support Custom Objects, we migrate the current balance snapshot as a Note on the Candidate record with a structured text format.

Adapt

Compensation History

maps to

Bullhorn ATS & CRM

Custom Object (Candidate-attached) or Custom Fields

1:1
Mapping required

Adapt salary and compensation records migrate as a Custom Object attached to the Candidate with effective date, compensation type (salary, bonus, commission), amount, and currency fields. Bullhorn does not have a native compensation history object, so the Custom Object approach preserves the full compensation timeline. For customers on Bullhorn editions without Custom Object support, we migrate the most recent compensation record as custom fields on the Candidate and flag the historical records for manual entry.

Adapt

Job/Position

maps to

Bullhorn ATS & CRM

JobOrder

1:1
Fully supported

Adapt job title and position records map to Bullhorn JobOrder. Job title, description, department, employment type (full-time, contract), and pay rate migrate to Bullhorn JobOrder's title, description, categories, employmentType, and payRate fields. The Adapt job's status (open, filled, closed) maps to Bullhorn JobOrder status. We preserve the Adapt job's custom fields on the JobOrder or in a Custom Object depending on the Bullhorn edition tier.

Adapt

Owner

maps to

Bullhorn ATS & CRM

User

1:1
Fully supported

Adapt Owners map to Bullhorn User records by email match. We extract every distinct Adapt Owner referenced on Employee, Contact, Company, and Job records and match against the Bullhorn destination's User table. Any Adapt Owner without a matching Bullhorn User goes to a reconciliation queue for the customer's admin to provision before record import resumes. OwnerId references on Bullhorn records are required for JobOrder, Candidate, and ClientCorporation.

Adapt

Notes and Attachments

maps to

Bullhorn ATS & CRM

Note and ContentDocument

1:1
Fully supported

Adapt notes and file attachments migrate to Bullhorn Note records (for text notes) and ContentDocument records (for file attachments) linked via ContentDocumentLink to the parent Candidate, ClientContact, ClientCorporation, or JobOrder. We preserve the note body as rich text and map file attachments to Bullhorn's Document records with the original filename and MIME type retained.

Adapt

Activity History (calls, emails, meetings)

maps to

Bullhorn ATS & CRM

Task, Event, EmailMessage

1:1
Fully supported

Adapt engagement history (call logs, email records, meeting records) migrates to Bullhorn as Task records (calls with TaskSubtype=Call), Event records (meetings with start and end times), and EmailMessage records (emails linked to an Activity Task). The activity timestamp preserves the original Adapt date so the Bullhorn Activity timeline remains in chronological order. If Adapt stores engagement metadata as custom properties rather than native activity records, we map them to Bullhorn custom fields on the Candidate or ClientContact.

Adapt

User Permissions and Roles

maps to

Bullhorn ATS & CRM

Bullhorn Admin User Setup

lossy
Fully supported

Adapt user roles and permissions do not migrate directly to Bullhorn's user permission model. Bullhorn uses a role-based access control (RBAC) system with Admin, Standard, and Limited user types. We deliver a written role and permission mapping document that describes each Adapt user's current permissions and a Bullhorn role equivalent. The customer's Bullhorn admin rebuilds the permission structure post-migration based on the documented mapping.

Pair-specific challenges

  • Adapt's API access is unconfirmed and may require CSV fallback

    The Adapt platform does not have a publicly documented REST API in current research. Bullhorn's documented REST API supports Custom Object CRUD via the /meta endpoint, Bulk API 2.0 for large record volumes, and standard CRUD for Candidate, ClientContact, ClientCorporation, JobOrder, and related entities. We verify API access directly with Adapt during discovery. If Adapt's API is inaccessible or rate-limited below migration requirements, we fall back to structured CSV export and CSV-based Bullhorn import, which limits field coverage and requires manual post-migration validation. We flag this uncertainty in the discovery phase and scope accordingly.

  • Bullhorn Custom Object tier limits constrain custom property mapping

    Bullhorn editions impose strict Custom Object limits: ATS Growth supports zero custom objects, ATS supports 2 custom objects (55 fields each), and Growth/Enterprise supports 10 custom objects (55 fields each). Adapt's custom employee properties may exceed these limits depending on the customer's Adapt tier and usage. We audit the Adapt custom property count during discovery and map to the target Bullhorn edition's limits. Fields that cannot fit within the edition's Custom Object budget are flagged for the customer's admin to prioritize, consolidate into multi-value fields, or defer to post-migration manual entry.

  • PTO and compensation data have no native Bullhorn object

    Bullhorn's standard ATS objects do not include native PTO accrual tracking or compensation history fields. Adapt stores these as standard data types, but Bullhorn requires a Custom Object to replicate the structure. If the customer's Bullhorn edition does not support Custom Objects (ATS Growth), we can only migrate current PTO balance and most recent compensation as snapshot values on the Candidate record. Full accrual history and compensation timeline require either a Custom Object upgrade or manual post-migration entry. We identify this gap during scoping and present the upgrade path or truncation option before migration begins.

  • Adapt-originated enrichment metadata has no standard Bullhorn field

    Adapt's browser extension stores contact enrichment data including email-find history, confidence scores, and data source flags as custom fields on Contact records. Bullhorn's standard ClientContact object does not have equivalent enrichment metadata fields. We migrate these values to Bullhorn Custom Objects attached to ClientContact when the edition supports it. Bullhorn ATS Growth customers (zero Custom Objects) lose enrichment metadata unless it fits within Bullhorn's standard ClientContact custom field budget of 500 fields. We audit the enrichment field count during discovery and present a mapping strategy for each edition tier.

  • Saved searches and custom list views do not migrate

    Adapt saved searches and custom list views are user-specific configuration data that does not migrate to Bullhorn. Bullhorn's own saved search migration documentation shows that even Bullhorn-to-Bullhorn migrations require manual recreation of saved searches in the new Candidate List experience. We document every Adapt saved search and custom list view as part of the migration inventory and deliver a written reference list for the customer's admin to recreate in Bullhorn. Address fields, advanced credential searches, and file attachment filters in Adapt saved searches map to Bullhorn field equivalents where they exist; unsupported fields are flagged for manual filter adjustment.

Migration approach

Six steps for a successful Adapt to Bullhorn ATS & CRM data migration

  1. Discovery and API access verification

    We audit the Adapt environment across all tiers, extracting record counts for Employees, Contacts, Companies, Departments, Jobs, custom properties, PTO balances, compensation records, notes, and attachments. We verify API access with Adapt directly during discovery: if the API is accessible, we use it for automated export; if not, we prepare a structured CSV export workflow. We also audit the target Bullhorn edition's Custom Object limits and match Adapt's custom property count against the tier budget. The discovery output is a written migration scope document including record counts, API access confirmation, Custom Object overflow plan, and Bullhorn edition recommendation.

  2. Bullhorn schema design and Custom Object configuration

    We design the Bullhorn destination schema in a Sandbox environment. This includes provisioning Custom Objects (up to the edition limit of 2 or 10), custom fields on Candidate, ClientContact, and ClientCorporation, Category records for department mapping, JobOrder record types, and Bullhorn field mappings for each Adapt source field. Bullhorn Custom Objects must be requested through Bullhorn Support with a completed Custom Object Setup Spreadsheet; we prepare this spreadsheet with the Adapt-sourced field definitions during this phase. Schema is validated in Sandbox before production deployment.

  3. Owner and User provisioning reconciliation

    We extract every distinct Adapt Owner referenced on Employee, Contact, Company, and Job records and match by email against the Bullhorn destination's User table. Any Adapt Owner without a matching Bullhorn User goes to a reconciliation queue for the customer's Bullhorn admin to provision before record import resumes. OwnerId references are required on Bullhorn JobOrder, Candidate, and ClientCorporation records, so this step must complete before production migration begins. We provide a User provisioning template with the required fields (firstName, lastName, email, userType) for each missing Owner.

  4. Sandbox migration and reconciliation

    We run a full migration into a Bullhorn Sandbox using production-like data volume. The customer's Bullhorn admin reconciles record counts (Candidates in, ClientContacts in, ClientCorporations in, JobOrders in, Custom Object instances in), spot-checks 25-50 random records against the Adapt source, and validates that custom property values, PTO balances, compensation history, and enrichment metadata landed correctly in Bullhorn. Any field mapping corrections, Custom Object overflow handling, or data type mismatches are resolved in the Sandbox before production migration begins.

  5. Production migration in dependency order

    We run production migration in record-dependency order: Categories (department hierarchy first), ClientCorporation (from Adapt Companies), ClientContact (with ClientCorporationId resolved), Candidate (with CategoryId and OwnerId resolved), JobOrder (with ClientCorporationId, CategoryId, and OwnerId resolved), PTO and compensation Custom Objects (attached to Candidate by CandidateId), notes and attachments (via ContentDocument and ContentDocumentLink), and engagement history (Tasks, Events, EmailMessages via Bulk API where available). Each phase emits a row-count reconciliation report before the next phase begins.

  6. Cutover, validation, and automation rebuild handoff

    We freeze Adapt writes during cutover, run a final delta migration of any records modified during the migration window, then enable Bullhorn as the system of record. We deliver a written inventory of Adapt saved searches, custom list views, and user role configurations requiring manual rebuild in Bullhorn. We do not migrate Bullhorn Workflows, Sequences, or Automations as code; these are scoped separately with a Bullhorn partner or the customer's internal admin. We support a one-week hypercare window where we resolve any record count discrepancies, field mapping errors, or Custom Object configuration issues raised during the first week of Bullhorn production use.

Most Adapt migrations land between two and four weeks for accounts under 5,000 Employees and 10,000 Contacts when Adapt's API is accessible. Migrations requiring CSV fallback export (API unconfirmed), large compensation histories, or Bullhorn ATS Growth edition (Custom Object limit of zero) move to six to ten weeks because of manual export coordination, field-level transformation, and Bullhorn Custom Object schema configuration per edition tier. Bullhorn's own implementation documentation notes two-week go-live for small agencies and two to six weeks for larger agencies; we align our data migration phases with that cadence.
