Overview
Moving from TalentNest to Bullhorn is a platform migration where the most complex work is translating TalentNest's stage-based workflow containers and proprietary screening instruments into Bullhorn's Candidate-JobOrder-Placement data model. TalentNest stores assessment scores as job-specific custom fields on Applications with no standardized schema; we export all of them as key-value pairs, pre-coordinate Bullhorn Custom Object creation with Bullhorn Support, and map the screening data into up to ten searchable Custom Objects on Candidate and JobOrder records. Bullhorn's Tracks feature (Enterprise tier) lets you define multiple employment-type variants per JobOrder, which handles the TalentNest scenario of jobs with different hiring processes for the same role. TalentNest's application-date-reset behavior means we must source canonical submission timestamps from the audit trail rather than the record's modified date. Email templates, SMS templates, and job board distribution settings do not migrate as functional code; we deliver a structured template inventory and job-board distribution log for your Bullhorn admin to reconfigure post-migration.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a TalentNest 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.
TalentNest
Job
Bullhorn ATS & CRM
JobOrder
1:1TalentNest Jobs map 1:1 to Bullhorn JobOrder records. Each TalentNest Job's title, description, location, and status transfer directly. Bullhorn's employmentType field on JobOrder captures the hire type (Direct Hire, Contract, etc.). For TalentNest jobs with multiple workflow variants (e.g., same role hired as W2 vs 1099), Bullhorn's Tracks feature (Enterprise) lets you configure Track I, Track II, etc. with different field visibility. We map TalentNest stage definitions to a written JobOrder configuration document so your Bullhorn admin recreates the stage sequence in Bullhorn's workflow builder.
TalentNest
Candidate
Bullhorn ATS & CRM
Candidate
1:1TalentNest Candidate profiles (contact details, resume, demographics, notes) map directly to Bullhorn Candidate records. The candidate's name, email, phone, and address fields migrate as typed fields. Resume files migrate as Bullhorn Candidate attachments linked via ContentDocumentLink. We resolve the TalentNest candidate email as the dedupe key to prevent duplicate Candidate creation if the candidate applied to multiple jobs.
TalentNest
Application
Bullhorn ATS & CRM
JobSubmission
1:1TalentNest Application junction records (linking a Candidate to a Job with status, rating, and stage history) map to Bullhorn JobSubmission. The application status maps to Bullhorn's application status field, and the stage transition history migrates as a sequence of status-change records with timestamps. We source submission timestamps from TalentNest's audit trail to avoid the application-date-reset issue.
TalentNest
Screening/Assessment Results
Bullhorn ATS & CRM
Custom Object (Candidate-linked)
1:1TalentNest stores proprietary screening scores as job-specific custom fields on Applications with no standardized schema across jobs. We export all screening fields as key-value pairs and map them into Bullhorn Custom Objects (up to 10 for Front Office Growth/Enterprise, 2 for Bullhorn ATS). Bullhorn Support must create the Custom Object definitions; we provide a field specification spreadsheet with field names, types, and Bullhorn-equivalent edit types (text, drop-down, numeric). Assessment scores that exceed the 55-field Custom Object limit are split across two Custom Objects.
TalentNest
Workflow Stages
Bullhorn ATS & CRM
JobOrder Stage Configuration (documented)
lossyTalentNest stage-based workflow automation (email triggers, SMS triggers, stage conditions) does not migrate as functional code. Bullhorn's workflow automation lives in Bullhorn Automation (Herefish) or is rebuilt by the admin in Bullhorn's workflow builder. We export the full stage definition including trigger actions, email template bodies, and automation rules as a structured configuration document. Your Bullhorn admin uses this to recreate stages in Bullhorn's JobOrder setup.
TalentNest
Users/Hiring Managers
Bullhorn ATS & CRM
User
1:1TalentNest User accounts with roles and access permissions map to Bullhorn User records. We resolve by email match. Any TalentNest User without a matching Bullhorn User goes to a reconciliation queue for your Bullhorn admin to provision before record import resumes. Hiring manager assignment on Jobs migrates as the Bullhorn User on the JobOrder record.
TalentNest
Notes and Comments
Bullhorn ATS & CRM
Note
1:1Recruiter notes attached to candidate profiles in TalentNest migrate to Bullhorn Note records linked via ContentDocumentLink to the Candidate record. Author, timestamp, and full note body are preserved. Bullhorn Note supports up to millions of characters per note, which accommodates even lengthy assessment notes from TalentNest.
TalentNest
Referrals
Bullhorn ATS & CRM
Custom Field or Custom Object (Candidate-linked)
lossyReferral source data on TalentNest Applications (available on Business and Enterprise tiers) migrates to a Bullhorn custom field on Candidate. If your TalentNest account was on Starter or Growth, referral data is absent (null) and we surface this as a tier-gap note. We flag any candidates who were referred so your Bullhorn admin can configure a referral source tracking workflow post-migration.
TalentNest
Talent CRM Database
Bullhorn ATS & CRM
Candidate (pool)
1:manyTalentNest's Talent CRM (Growth and above) stores candidate profiles outside of active job applications. We export all CRM candidate records and map them as Candidate records in Bullhorn. Candidates with no active application in TalentNest land in Bullhorn as Candidate records without a JobSubmission; we flag these as CRM-pool records so your Bullhorn admin can configure them as a talent pool or source list.
TalentNest
Email/SMS Templates
Bullhorn ATS & CRM
Email Template Documentation (documented)
lossyTalentNest email and SMS templates tied to workflow stages export as template body and metadata records. Since template IDs are proprietary to TalentNest, they cannot be re-imported into Bullhorn. We deliver a template inventory document listing every TalentNest template with its body, trigger conditions, and stage association so your Bullhorn admin creates equivalent Bullhorn email templates and SMS templates in Bullhorn Automation or Bullhorn's native template builder.
TalentNest
Job Board Distribution Settings
Bullhorn ATS & CRM
Job Distribution Log (documented)
lossyTalentNest's 30+ board distribution configuration per Job is exported as a distribution list property. Bullhorn's native job distribution covers Indeed, LinkedIn, and major aggregators but does not natively replicate all 30+ TalentNest boards. We provide a job-board distribution log mapping each TalentNest board to its Bullhorn-equivalent or third-party integration (if available), and your Bullhorn admin configures distribution per JobOrder post-migration.
TalentNest
Custom Fields
Bullhorn ATS & CRM
Custom Fields
1:1TalentNest pre-screen and demographic custom fields on Applications export with field types, labels, and answer options. We map each to a Bullhorn custom field on JobSubmission or Candidate, using the appropriate Bullhorn field type (text, drop-down, numeric, checkbox). Bullhorn field character limits vary (some capped at 100 characters, others at millions); we analyze your TalentNest data to ensure no truncation occurs during import.

Migration approach
Discovery and TalentNest data audit
We audit your TalentNest account across plan tier, active jobs, candidate volume, application history, screening instrument count per job, workflow stage definitions, user count, and CRM pool size. We also identify tier-gated features present in your account (job board distribution, referral tracking, Talent CRM) versus those absent (Starter/Growth accounts). The discovery output is a written migration scope specifying record counts per object, Custom Object field counts per job, and any TalentNest features that will not appear in the export due to tier limitations.
Bullhorn Custom Object pre-configuration
We create a Custom Object Setup Sheet for Bullhorn Support based on the TalentNest screening schema audit. This spreadsheet specifies each Custom Object's fields, types, hints, and edit types. We submit the ticket to Bullhorn Support on your behalf and coordinate the 24-48 hour fulfillment window. Bullhorn Support creates the Custom Object definitions in your Bullhorn environment. Once confirmed, we validate the schema via a REST API meta call before any data import begins.
Sandbox migration and mapping validation
We run a full migration into a Bullhorn Sandbox using production-like data volume. Bullhorn field character limits (some capped at 100 characters, others supporting millions) are validated against TalentNest source data lengths. We test the Custom Object import, confirm that assessment key-value pairs land in the correct Bullhorn fields, and reconcile record counts (Candidates in, JobOrders in, JobSubmissions in, Notes in) against the TalentNest export. Your Bullhorn admin spot-checks 25-50 records before production migration is approved.
Owner reconciliation and Bullhorn User provisioning
We extract every distinct TalentNest User referenced on Jobs, Candidates, Applications, and Notes and match by email against Bullhorn User records in the destination environment. Any TalentNest User without a matching Bullhorn User goes to a reconciliation queue. Your Bullhorn admin provisions missing Users (and optionally sets them to Inactive if the original TalentNest user is no longer active) before record migration proceeds.
Production migration in dependency order
We run production migration in record-dependency order: JobOrders (from TalentNest Jobs), Candidate records (with resume attachments), Bullhorn User validation, JobSubmissions (with application status and stage history sourced from TalentNest audit trail for submission dates), Notes and Comments, Screening/Assessment data (into pre-configured Custom Objects), referral data (into custom Candidate fields), and CRM pool candidates (candidates with no active JobSubmission). Each phase emits a row-count reconciliation report. Application date reconciliation (original submission vs touch date) is applied at the JobSubmission phase.
Template inventory delivery and admin handoff
We deliver the TalentNest email/SMS template inventory, job board distribution log, workflow stage configuration document, and automation trigger map. Your Bullhorn admin uses these to recreate email templates in Bullhorn, configure job distribution per JobOrder, and rebuild stage-triggered workflows in Bullhorn Automation. We support a one-week hypercare window for reconciliation issues. We do not rebuild TalentNest workflows, templates, or automations inside the migration scope; these require your Bullhorn admin or a Bullhorn implementation partner.
