Overview
Moving from The Applicant Manager to BambooHR is a platform consolidation as much as a data migration. TAM is a standalone ATS that exports candidate records as a password-protected CSV plus a separate zip archive of applicant files, with no public REST API and customer-defined workflow stage names that vary by tenant. BambooHR is an HRIS with a built-in ATS module (available via the Advantage package) that imports candidates via API against job openings and natively connects hiring data to employee records, PTO, and onboarding. We handle the two-package extraction, re-associate every resume and cover letter to its candidate, and design the BambooHR stage pipeline before any records load. Workflow configurations, email templates, and onboarding form logic do not migrate; we deliver a written inventory of these for your admin to rebuild in BambooHR Hiring.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a The Applicant Manager 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.
The Applicant Manager
Position (Job Posting)
BambooHR
Job Opening
1:1TAM Positions (job title, description, department, status) map directly to BambooHR Job Openings. The TAM position status (active, closed, on hold) maps to BambooHR's Job Opening status field. We extract all active and closed positions from the TAM CSV during the initial export, preserving the original posting date and any department classification. BambooHR requires Job Openings to be created before Applicants can be attached, so positions load first in the dependency sequence.
The Applicant Manager
Applicant
BambooHR
Candidate
1:1TAM Applicant records (contact information, application date, source attribution, current workflow stage) map to BambooHR Candidate records attached to the corresponding Job Opening. We map the TAM applicant ID as a reference field and preserve the application date as the candidate's submission timestamp. Custom profile fields from TAM map to BambooHR's custom candidate fields. If the candidate email matches an existing BambooHR Employee record, we link the Candidate to the Employee for onboarding continuity.
The Applicant Manager
Workflow Stage
BambooHR
Hiring Pipeline Stage
lossyTAM's customizable workflow stages have no standard naming vocabulary—every TAM tenant defines its own stage names and sequence. We collect the complete TAM workflow configuration during discovery, then configure the BambooHR Hiring pipeline with matching stage names in the same order. The stage order is preserved so candidate progress reflects correctly after cutover. If TAM had five stages (Applied, Phone Screen, Interview, Offer, Hired), BambooHR gets five matching pipeline stages.
The Applicant Manager
Resume and Cover Letter
BambooHR
Candidate File Attachment
1:1TAM stores applicant files in a separate password-protected zip archive, not embedded in the CSV export. We download and unpack both the CSV and the file archive, then cross-reference each file by applicant ID or filename pattern to re-associate it with the correct BambooHR Candidate record. Resume and cover letter files upload as attachments to the candidate profile in BambooHR Hiring. This two-step extraction is the most manual part of the migration and adds processing time for large file volumes.
The Applicant Manager
Screening Question
BambooHR
Custom Application Question
1:1TAM supports custom application questions stored in the position configuration, with responses per applicant. We extract both the question schema (question text, answer type, required flag) and the applicant responses. Questions migrate as Custom Application Questions in BambooHR; responses attach to the corresponding Candidate record. Formatting of free-text responses is preserved; multi-select or dropdown responses map to BambooHR's equivalent answer type.
The Applicant Manager
Activity Notes and Scorecards
BambooHR
Activity History Entry
1:1Hiring team notes, scorecard ratings, and stage-change timestamps tracked per TAM applicant migrate as Activity History entries in BambooHR. We preserve the author (hiring manager or recruiter), timestamp, and content. Scorecard ratings with structured attributes migrate as formatted text notes. Formatting varies depending on how the destination BambooHR account renders activity history, and the customer's ATS package tier affects how rich the activity display is.
The Applicant Manager
Onboarding Documents
BambooHR
BambooHR Onboarding
1:1TAM includes onboarding paperwork collection with document metadata and storage references. Document metadata migrates to BambooHR Onboarding, but the destination system's onboarding module acceptance determines whether forms are fully functional post-migration. BambooHR's onboarding is tied to the BambooHR Employee record, so the candidate must have been converted to an Employee (or have a matching Employee record) for onboarding tasks to attach. We flag any forms that require manual reconfiguration in BambooHR Onboarding.
The Applicant Manager
User and Hiring Manager
BambooHR
BambooHR Employee
1:1TAM user accounts tied to applicant assignments and workflow actions map to BambooHR Employee records. We match by email address and preserve assignment ownership so that the hiring manager responsible for each TAM applicant is linked to the corresponding BambooHR Candidate. TAM users without matching BambooHR Employee records go to a reconciliation queue for the customer's admin to provision before the migration batch completes.
The Applicant Manager
Position Department
BambooHR
BambooHR Department
1:1TAM positions carry a department classification. We extract department names from the TAM CSV and map them to existing BambooHR Department records, or flag missing departments for the customer to create before position migration. Department assignment on Job Openings in BambooHR references the HRIS department list, so this lookup must be satisfied at migration time.
The Applicant Manager
Applicant Source
BambooHR
Candidate Source
1:1TAM tracks applicant source (Indeed, LinkedIn, Referral, etc.) in the applicant record. Source attribution migrates as the Candidate Source field in BambooHR Hiring. We map the TAM source label directly, with a reconciliation pass if the customer's BambooHR account uses a different source vocabulary. Source data is preserved for reporting on hiring channel effectiveness.

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.
The Applicant Manager gotchas
Feature-based per-month pricing compounds with team size
No publicly documented REST API
Custom workflow stages lack standardized naming
Resume and cover letter files are stored separately from the CSV export
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 package collection
We audit the TAM instance during a scoped discovery session, extracting the complete workflow stage configuration, active and closed position list, user and hiring manager roster, and any custom application question schemas. We then coordinate with the customer to obtain both the password-protected Standard Applicant Data CSV and the password-protected applicant file zip archive. We verify the file counts match (number of applicants in CSV vs. number of files in zip) and flag any discrepancies. We also confirm the customer's BambooHR subscription tier and whether the Advantage package for Hiring is active, as ATS functionality is gated by this entitlement.
BambooHR pipeline and schema configuration
We design the BambooHR Hiring pipeline before any records load. This includes creating pipeline stages that match the TAM workflow stage names in the same order, configuring the Job Opening departments to match TAM's department vocabulary, and setting up custom candidate fields for any TAM custom profile fields that do not have a direct BambooHR equivalent. The BambooHR admin grants API key access, and we validate connectivity. Schema configuration happens in the customer's live BambooHR environment or a sandbox if the customer prefers validation before production.
File extraction and re-association
We unpack the TAM file zip archive in a secure staging environment, building a filename-to-applicant-ID cross-reference using the TAM CSV. For each file, we identify the applicant it belongs to by matching filename patterns or applicant ID embedded in the filename. We produce a manifest mapping each applicant to their resume, cover letter, and any other attachments. This manifest drives the file upload step during the candidate migration phase. Large file volumes require batched processing to avoid timeout issues during the BambooHR file attachment API calls.
Sandbox migration and reconciliation
We run a full migration into the customer's BambooHR environment (or a sandbox if preferred) with production-like data volumes. The customer's HR administrator reconciles record counts (positions in, applicants in, attachments matched), spot-checks 25-50 candidate records against the TAM source for accuracy, and verifies that workflow stages display in the correct order. Any stage mapping corrections, custom field additions, or department mismatches are resolved here before the production migration begins. We do not proceed to production until the sandbox migration passes reconciliation sign-off.
Production migration in dependency order
We run production migration in record-dependency order: first BambooHR Departments (if new), then Job Openings (from TAM Positions), then Candidate records (with stage assigned, department linked, and source attribution), then file attachments (resumes and cover letters matched via the file manifest), then Activity History entries. Each phase emits a row-count reconciliation report before the next phase begins. The TAM instance is placed in read-only mode during the final migration window to capture any delta records created between discovery and cutover.
Cutover, validation, and onboarding handoff
We freeze TAM writes during cutover, run a final delta migration of any records modified during the migration window, then confirm BambooHR as the active hiring system. We deliver a written inventory of TAM workflow configurations and onboarding form templates requiring rebuild in BambooHR, with step-by-step configuration guidance for each. We support a one-week hypercare window where we resolve any reconciliation issues raised by the recruiting team. We do not rebuild TAM workflow stages or onboarding task sequences inside the migration scope; these are rebuilt by the customer's BambooHR admin or an implementation partner as a separate engagement.
