Overview
Moving from CVViZ to Bullhorn is a migration from an AI-first startup ATS to the most widely deployed recruitment cloud in the staffing industry. CVViZ organizes hiring around Jobs, Candidates, and Applications with configurable pipeline stages and an AI scoring layer; Bullhorn uses JobOrder, Candidate, and JobSubmission entities with a separate ClientCorporation and ClientContact model for staffing-agency workflows. We handle the schema translation between CVViZ's per-organization stage names and Bullhorn's jobOrderstatus and dateSubmitted values, treat CVViZ Resume files as binary attachments that must be extracted and re-attached in Bullhorn via the REST API's file endpoints, and carry CVViZ AI scores as custom numeric fields on Bullhorn Candidate records. Workflows, automation rules, and AI ranking models do not migrate as code; we deliver a written inventory for Bullhorn rebuild. Bullhorn's ATS Growth edition does not include API access, which constrains the destination tier for migrations requiring Bullhorn REST API connectivity.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a cvviz 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.
cvviz
Job
Bullhorn ATS & CRM
JobOrder
1:1CVViZ Job records (title, description, department, location, employment type) map directly to Bullhorn JobOrder. The jobOrderStatus and dateSubmitted fields in Bullhorn correspond to CVViZ's job status and created-at timestamp. CVViZ active-job limits (5-50 per tier) determine how many Jobs migrate as active; any Jobs beyond the target Bullhorn tier are imported as archived. Job board distribution settings (LinkedIn, Google for Jobs) are preserved as metadata but require re-publishing on the destination platform since Bullhorn distributes via Bullhorn Advertising and OpenWeb.
cvviz
Candidate
Bullhorn ATS & CRM
Candidate
1:1CVViZ Candidate records with name, email, phone, social profiles, employment history, and skills map 1:1 to Bullhorn Candidate. Email address is the dedupe key; Bullhorn enforces email uniqueness per Candidate record. Social profile URLs (LinkedIn, GitHub, Stack Overflow) from CVViZ migrate to Bullhorn Candidate socialNativeID or custom text fields. CVViZ's contact fields (address, timezone, preferred contact method) map to Bullhorn Candidate address, timeZone, and preferredContact fields.
cvviz
Resume
Bullhorn ATS & CRM
Candidate (file attachment)
1:1CVViZ stores parsed resume data as structured fields plus raw PDF/DOCX binary files. We extract the binary file and attach it to the Bullhorn Candidate record via the Bullhorn REST API file upload endpoints (/file/{entityType}/{entityId}) and link via contentDocumentLink. Parsed resume fields (summary, education, work experience) migrate to Bullhorn Candidate custom fields. Bullhorn does not run its own resume parser during import; the raw file lands unparsed unless the customer licenses Bullhorn AI resume summarization separately.
cvviz
Application
Bullhorn ATS & CRM
JobSubmission
1:1CVViZ Application records link a Candidate to a Job with a current pipeline stage and timestamp. These map to Bullhorn JobSubmission with the candidateID and jobOrderID lookups resolved at migration time. The CVViZ application dateSubmitted maps to Bullhorn dateSubmitted; application status maps to JobSubmission status. We preserve the candidate journey through each stage by mapping CVViZ stage timestamps to JobSubmission custom fields if the customer tracks stage history.
cvviz
Pipeline Stage
Bullhorn ATS & CRM
JobOrder (status map)
lossyCVViZ pipeline stage names are fully customizable per organization with no universal schema. We capture the complete CVViZ stage map during pre-migration schema review, then apply a named mapping to Bullhorn's jobOrderStatus values and any custom status definitions configured in the Bullhorn ATS. Stages with no Bullhorn equivalent are flagged for the customer's Bullhorn admin to configure in Bullhorn Admin > Job Order Status before the final import run. Stage probability percentages, if tracked in CVViZ, migrate to Bullhorn opportunitySuccessRate on the associated Placement entity.
cvviz
Talent Pool
Bullhorn ATS & CRM
Candidate (passive tag)
1:1CVViZ Talent Pool entries are passive candidates not tied to a specific active job requisition. We migrate these as Bullhorn Candidate records with a custom passiveTag__c flag set to true, preserving the original source attribution (LinkedIn, GitHub, Stack Overflow, referral) in candidateSource or a custom field. Passive candidates do not have an associated JobSubmission in Bullhorn; they land in the Bullhorn Talent Pool equivalent via Bullhorn's candidate search and talent management features.
cvviz
Candidate Scoring / Ranking
Bullhorn ATS & CRM
Candidate (custom numeric field)
1:1CVViZ AI candidate scores are calculated from its proprietary NLP model against the job description and historical hiring data. We carry the score value as a custom numeric field cvvizAIScore__c on the Bullhorn Candidate record. Bullhorn will not recalculate or update this score; it serves as a one-time snapshot from CVViZ. We recommend documenting the score distribution and setting expectations that Bullhorn AI will generate its own candidate-job fit scores through its own model. The original CVViZ score becomes informational only.
cvviz
Pre-Screening Questions
Bullhorn ATS & CRM
JobSubmission (custom fields)
1:1CVViZ stores job-specific pre-screening questions and candidate responses as key-value pairs on the Application. We map these to Bullhorn JobSubmission custom fields (using the Bullhorn REST API to create custom fields on the JobSubmission entity) or to custom fields on the JobOrder if the questions are job-level. Questions with no Bullhorn equivalent are flagged in the scoping report with a recommended custom field type. Responses migrate as string values with the question text stored as the field label.
cvviz
Job Board Distribution
Bullhorn ATS & CRM
JobOrder (metadata)
lossyCVViZ job board distribution settings (LinkedIn, Google for Jobs, Indeed, and other boards) are stored as job metadata in CVViZ. We preserve the distribution configuration as a custom text field jobBoardDistribution__c on Bullhorn JobOrder. The actual job postings do not transfer as live links; they must be re-created and published in Bullhorn via Bullhorn Advertising or the individual job board's Bullhorn-integrated connector. We flag all job boards requiring re-activation after migration.
cvviz
User / Team Member
Bullhorn ATS & CRM
User
1:1CVViZ Users map to Bullhorn User records by email address. We resolve each CVViZ Owner (recruiter, hiring manager, admin) referenced on Jobs, Candidates, and Applications and match by email against the Bullhorn destination org's User table. Any CVViZ Owner without a matching Bullhorn User goes to a reconciliation queue for the customer's Bullhorn admin to provision. Custom role permissions from CVViZ are documented in the scoping deliverable; Bullhorn's role-based access is configured separately in Bullhorn Admin > Users & Permissions.
cvviz
Custom Fields
Bullhorn ATS & CRM
Custom Fields
1:1CVViZ custom fields on Jobs and Candidates (excluding AI scores and pre-screening questions) migrate to Bullhorn custom fields on the equivalent entity. We pre-create Bullhorn custom fields via the Bullhorn REST API before migration, matching CVViZ field names to Bullhorn custom field API names with the appropriate Bullhorn data type (string, integer, float, boolean, date, enum). Bullhorn Admin Field Mappings (field-level control on Add/Edit pages) are configured separately by the customer's Bullhorn admin post-migration.
cvviz
Client / Organization
Bullhorn ATS & CRM
ClientCorporation
1:1CVViZ does not have a separate client/corporation entity, but Bullhorn's staffing workflow requires ClientCorporation records for agency clients. We create Bullhorn ClientCorporation records from CVViZ organization-level data if present, or from the company's own employer-of-record profile if the customer is an agency. If the customer is a direct employer using CVViZ without client accounts, we configure ClientCorporation as the employer's company record to enable Bullhorn's placement and billing workflow.
cvviz
Automation Rules
Bullhorn ATS & CRM
Bullhorn Automation (documented, not migrated)
lossyCVViZ automation rules (email triggers, notifications, stage transitions) are platform-specific and do not map cleanly to Bullhorn Automation. Bullhorn Automation uses event subscriptions and webhook steps to trigger actions on record changes, but the trigger logic, conditions, and action sets are structurally different. We document each CVViZ automation rule with its trigger, conditions, and actions in a written handoff inventory. Bullhorn's admin rebuilds these in Bullhorn Automation or via Bullhorn's workflow configuration tools post-migration.

Migration approach
Discovery and Bullhorn edition verification
We audit the source CVViZ account for record counts (Jobs, Candidates, Applications, Talent Pool entries), resume library size, pipeline stage definitions, active job count relative to the CVViZ pricing tier, custom fields on Jobs and Candidates, automation rules, and integration configuration. We simultaneously verify the destination Bullhorn edition to confirm API access is enabled (not ATS Growth), assess existing Bullhorn schema against the CVViZ data model, and identify any ClientCorporation setup required for staffing-agency workflows. The discovery output is a written migration scope with a Bullhorn edition recommendation and a pre-migration Bullhorn admin checklist.
Schema alignment and stage mapping design
We design the destination Bullhorn schema before any data moves. This includes mapping CVViZ pipeline stages to Bullhorn jobOrderStatus values or custom Bullhorn status definitions, creating Bullhorn custom fields (using the Bullhorn REST API custom entity fields endpoints) to capture CVViZ AI scores, pre-screening question responses, and Talent Pool tags, and designing the ClientCorporation setup for agency clients. We configure any required Bullhorn Record Types and Sales Processes if the customer is using Bullhorn Opportunity management for direct-hire workflows. Bullhorn Field Mappings for custom field display are noted for the customer's Bullhorn admin to configure post-migration.
Sandbox migration and reconciliation
We run a full migration into a Bullhorn Sandbox or staging org using a representative data volume sample. The customer reconciles record counts (Candidates in, Jobs in, JobSubmissions in, Resume files attached), spot-checks 25-50 random Candidate records against the CVViZ source (checking resume attachment presence, AI score value, stage history, and custom field values), and validates that the Bullhorn stage mapping produces the expected status assignments. Mapping corrections, missing custom fields, and Bullhorn status configuration gaps are resolved here before production migration begins.
Binary resume extraction and batch preparation
We extract raw resume files from CVViZ in batches of 500, preserving the Candidate-to-Resume linkage via the CVViZ application ID. We chunk the resume library to manage Bullhorn API upload limits and prepare a file-to-candidate mapping manifest. Simultaneously, we extract structured Candidate fields, Application records, and Job records into CSV/JSON batches for the Bullhorn Bulk API or REST API import. All CVViZ pipeline stage names are replaced with their Bullhorn status equivalents in this phase using the pre-agreed stage mapping table.
Production migration in dependency order
We run production migration in record-dependency order: ClientCorporation records (for agency clients), JobOrder records (from CVViZ Jobs), Candidate records (with custom fields and Talent Pool tags), JobSubmission records (with candidateID and jobOrderID lookups resolved), User reconciliation (matching CVViZ Owners to Bullhorn Users by email), resume file attachments (via Bullhorn REST API file upload endpoints with rate-limit handling), and custom object data last. Each phase emits a row-count reconciliation report before the next phase begins. Bullhorn API calls are logged for audit and retry handling.
Cutover, validation, and automation rebuild handoff
We freeze CVViZ 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 the automation inventory document listing every CVViZ automation rule with trigger conditions and recommended Bullhorn Automation equivalents. We support a one-week hypercare window where we resolve reconciliation issues raised by the recruitment team. We do not rebuild CVViZ automation rules in Bullhorn Automation inside the migration scope; that work is handled by the customer's Bullhorn admin or a Bullhorn-certified partner using the delivered inventory.
