Overview
Moving from Paradox to BambooHR is a platform-type migration, not a direct object copy. Paradox organizes hiring around Candidates, Jobs, and Olivia chatbot interaction logs; BambooHR organizes HR around Employees, Departments, and an ATS layer scoped for small-to-mid-market hiring. The primary migration challenge is the mismatch between Paradox's conversational screening data (Olivia Q&A logs) and BambooHR's structured application-question model. We extract screening responses as structured records, map them to BambooHR application-note fields, and flag any untranslatable screening logic for the customer's admin to rebuild in BambooHR's workflow builder. Candidate PII is audited for GDPR consent and right-to-erasure flags before inclusion in the migration set. We do not migrate Paradox automations, Olivia chatbot configurations, or scheduling logic; we deliver a written inventory of these for the customer's admin to rebuild in BambooHR's onboarding and approval workflow tools.

Object mapping
Each row shows how a Paradox 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.
Paradox
Candidate
BambooHR
Job Applicant
1:1Paradox Candidates map to BambooHR Job Applicants. We extract the candidate's name, email, phone, address, work authorization, and EEOC fields from Paradox's native export and map them to the corresponding BambooHR application field. Candidates with a Paradox hired status migrate as employees in BambooHR only if the customer's BambooHR plan includes the onboarding module and the customer requests the post-hire employee record creation. GDPR-sensitive records with right-to-erasure flags are excluded from the migration set unless explicit consent documentation is provided.
Paradox
Job
BambooHR
Job Opening
1:1Paradox Jobs (open positions with pipeline stages and hiring-team assignments) map to BambooHR Job Openings. We preserve the job title, department assignment, employment type (full-time, part-time, hourly), location, and open or closed status. BambooHR's job opening limits vary by tier (5 on Core, 25 on Pro, 50 on Elite); we verify the customer's tier accommodates the job opening count during scoping and flag any overage before migration begins.
Paradox
Event
BambooHR
Interview (calendar integration)
1:1Paradox Events (scheduled interviews, assessments, or time-bound hiring activities) map to BambooHR's interview records. We extract event type, scheduled date and time, participant assignments (interviewer names and emails), and outcome status from Paradox. Interviewer assignments resolve by email match to BambooHR Employee records. If the Paradox event has a scheduling link from Olivia, we document the link as a note for the admin to re-create in BambooHR's calendar integration.
Paradox
Screening Response
BambooHR
Application Question / Note
lossyParadox Olivia screening Q&A logs do not map to a native BambooHR object. We export each screening response as a structured record (question text, candidate answer, timestamp, stage at which asked) and import them as BambooHR Application Notes attached to the Job Applicant. For multi-step screening with conditional branching, we flatten the answered path and note the branching decision in the Note body. Any screening logic (branch conditions, skip logic, score-weighted responses) is documented as a written configuration guide for the customer's BambooHR admin to implement using BambooHR's custom application questions.
Paradox
Employee
BambooHR
Employee
1:1Paradox Employee records (workers created after a successful hire in the Paradox HRIS layer) map to BambooHR Employee records. We migrate first name, last name, email, department, job title, location, employment status, and start date. Paradox's effective-date model for employment changes (promotions, title changes, status changes) is flattened to the current state at migration time; historical change logs are stored as BambooHR Employment History notes. If Paradox is the system of record for compensation data (salary, pay rate, bonus), we flag compensation as a migration add-on scope because BambooHR stores compensation in the Elite tier's Compensation Management module.
Paradox
Group
BambooHR
Department
1:1Paradox Groups (departments, locations, cost centers) map to BambooHR Departments. We preserve the group hierarchy (parent and child units) by creating a corresponding BambooHR Department with a parent-department relationship. Nested group depth beyond three levels is flattened into top-level departments with location-based subdivisions because BambooHR's department model supports two levels of nesting by default.
Paradox
Custom Field (Candidate)
BambooHR
Custom Field (Application)
lossyParadox custom fields on Candidates are captured during pre-migration discovery and mapped to BambooHR custom application fields. Field types are converted to closest BambooHR equivalents: free-text to Text Field, multi-select to Multi-Select, date to Date, and numeric to Number. Conditional logic on Paradox custom fields (show field X only if field Y equals Z) is documented as a configuration guide for BambooHR's conditional field rules in the application builder.
Paradox
Custom Field (Job)
BambooHR
Custom Field (Job Opening)
lossyParadox custom fields on Jobs migrate to BambooHR custom fields on Job Openings. We map the field name, type, and default value. BambooHR's custom job fields are visible on the job posting and in the applicant tracking view but do not automatically surface in the employee record post-hire. Any job-field-to-employee-field propagation logic from Paradox is documented for the admin to implement in BambooHR's onboarding template.
Paradox
Attachment (Candidate)
BambooHR
Employee File / Application Attachment
1:1Paradox candidate attachments (resumes, cover letters, portfolio files) are exported as binary files and re-uploaded to BambooHR as Employee Files (for post-hire records) or Application Attachments (for job applicants). File type, original filename, and upload timestamp are preserved. Any attachments stored outside Paradox's document layer (for example, in a linked S3 bucket or third-party storage referenced by Paradox) require a separate export step coordinated with the customer's IT team.
Paradox
Offer
BambooHR
Job Offer (BambooHR ATS)
1:1Paradox Offer records (compensation details, status, approval workflow data) map to BambooHR Job Offers in the ATS module. Compensation amount, offer status (pending, accepted, declined, withdrawn), and offer letter attachment migrate. Approval routing from Paradox (multi-step offer approvals) does not transfer as workflow configuration; we document the approval chain as a written step sequence for the customer's BambooHR admin to implement using BambooHR's approval workflow builder.
Paradox
Schedule
BambooHR
Availability / Calendar Note
1:1Paradox Schedule records (candidate availability windows and Olivia-scheduled calendar links) are exported as structured availability records and mapped to Interview records in BambooHR. Live calendar-linked scheduling links (Paradox's Calendar Sync feature) are documented as reconnection tasks for the customer's admin post-migration because BambooHR uses its own scheduling integration with Google Calendar and Outlook that requires re-authentication and re-configuration.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Paradox gotchas
Limited native bulk export forces reliance on ATS passthrough
GDPR candidate consent transfers require explicit handling
Implementation timeline delays migration start
Custom fields vary by customer and require discovery scoping
BambooHR gotchas
Undocumented API rate limits can trigger 503 errors
Per-employee pricing model requires active record count verification
API credentials must be sent on every request to avoid extra round trips
Custom field schema varies per account and requires manual inventory
Document and attachment exports are not covered by standard report exports
Pair-specific challenges
Migration approach
Discovery and export-path confirmation
We audit the Paradox instance for custom field schemas on Candidates and Jobs, active job count, candidate volume, screening response structure, employee records (if Paradox is the HRIS), group hierarchy depth, and attachment storage location. We simultaneously confirm the export path: if a live ATS connector (Workday, Greenhouse, or Lever) exists, we use it; if not, we request Paradox's native JSON export. We also verify GDPR consent status for all candidate records and identify any right-to-erasure or withdrawn-consent flags that require exclusion.
Schema design and custom field inventory
We design the destination BambooHR schema: custom application fields (mapped from Paradox Candidate custom fields), custom job fields (mapped from Paradox Job custom fields), department structure (from Paradox Groups), and employee fields (from Paradox Employees). For any Paradox screening logic (branching, skip conditions, score weighting), we produce a written configuration guide for BambooHR's application builder. For Paradox offer approval chains, we produce a written approval workflow document. All schema design is validated against the customer's BambooHR tier limits before migration begins.
Sandbox migration and reconciliation
We run a full migration into a BambooHR sandbox environment using production-like data volume. The customer's HR lead reconciles record counts (Candidates in, Applicants in, Jobs in, Employees in), spot-checks 25-50 random records against the Paradox source for field accuracy, and reviews the attached screening response notes for completeness. Any mapping corrections are made at this stage. If GDPR consent verification reveals a significant number of excluded records, we adjust the migration scope and update the pricing before production migration begins.
GDPR consent audit and record filtering
We apply the consent audit to the full candidate set. Records with right-to-erasure flags are excluded and logged. Records with withdrawn consent have interaction logs removed but base profile data migrates. We produce a consent audit log as part of the migration deliverable, which the customer retains for regulatory documentation. This step runs in parallel with sandbox reconciliation to avoid adding timeline length.
Production migration in dependency order
We run production migration in record-dependency order: Departments (from Paradox Groups), Job Openings (from Paradox Jobs, with department assignments resolved), Job Applicants (from Paradox Candidates, with GDPR flags applied and screening responses attached as notes), Interview records (from Paradox Events, with interviewer emails resolved to BambooHR Employee records), Employee records (from Paradox Employees, with department and title resolved), and Attachments (uploaded as Employee Files or Application Attachments). Each phase emits a row-count reconciliation report before the next phase begins.
Cutover, validation, and automation rebuild handoff
We freeze Paradox writes during cutover, run a final delta migration of any records modified during the migration window, then enable BambooHR as the system of record. We deliver the screening configuration guide, offer approval workflow document, and scheduling reconnection checklist to the customer's BambooHR admin team. We support a one-week hypercare window for reconciliation issues. We do not rebuild Paradox automations or Olivia chatbot configurations inside the migration scope; those are separate engagements or admin-level rebuilds.
