Overview
Moving from Gem to BambooHR is a category-crossing migration: Gem is a recruiting CRM centered on candidate sourcing, outreach sequences, and ATS pipeline management, while BambooHR is an HRIS built around the employee lifecycle from hire through offboarding. The primary migration vector is hired candidates becoming BambooHR Employees, with their contact information, work history, and applicable custom fields preserved. Gem Sequences, Projects, and engagement cadences do not migrate because BambooHR has no equivalent recruiting outreach model. We export Gem candidate records via its Admin Compliance settings, apply the hired-candidate filter, and import into BambooHR Employees. Unhired candidates in the talent pool are documented in a written handoff inventory for customers to manage manually post-migration or in a separate recruiting tool. Gem's LinkedIn handle deduplication logic is resolved during scoping to prevent duplicate candidate-to-employee records at import.
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 Gem 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.
Gem
Candidate (Hired)
BambooHR
Employee
1:1Gem Candidates with a hired status (determined by pipeline stage or a custom hired flag) map to BambooHR Employee records. We extract name, email, phone, LinkedIn URL, address, and any custom fields attached to the candidate. The Employee API endpoint is used for the primary import with employeeFields for standard attributes and the custom field API for non-standard values. Hired status is validated during extraction to avoid importing candidates still in the recruiting pipeline.
Gem
Candidate: Work History
BambooHR
Employee: Employment History
1:manyGem stores work history as structured sub-records on the Candidate object (company name, job title, start date, end date, description). BambooHR Employee records hold employment history in a dedicated section. We flatten work history into BambooHR's employment records, mapping the most recent position to the Employee's job title and hire date, and preserving additional positions as historical employment entries. Start and end dates transfer directly; descriptions map to a freeform notes field.
Gem
Candidate: Education
BambooHR
Employee: Education
1:manyGem stores education records (institution, degree, field of study, graduation date) on Candidate profiles. BambooHR supports education as an employee sub-section. We map institution name, degree, and graduation year directly; field of study maps to a freeform or custom field depending on the customer's BambooHR field configuration.
Gem
Candidate: Custom Fields
BambooHR
Employee: Custom Fields
lossyGem custom fields on Candidates (single-select, multi-select, date, freeform) map to BambooHR Employee custom fields. Field-type validation applies: BambooHR dropdown lists require exact value matches on import. We pre-create custom fields in BambooHR during schema design, validate that Gem values conform to BambooHR picklist options, and flag mismatches for customer review before migration. Freeform text fields map to BambooHR text fields without validation constraints. Multi-select fields in Gem map to multiple single-select custom fields in BambooHR if the destination does not support multi-select.
Gem
Candidate: Source
BambooHR
Employee: Application Source
1:1Gem tracks candidate sourcing channel (referral, LinkedIn, job board, inbound, etc.) as a field on the Candidate record. We map this to a BambooHR custom text field (e.g., originalSource__c) since BambooHR does not have a native candidate source field on Employee records. The customer configures whether this field appears on onboarding forms or employee profiles.
Gem
Candidate: LinkedIn Profile
BambooHR
Employee: LinkedIn URL
1:1Gem's linkedinHandle field contains the candidate's LinkedIn profile URL or handle. We map this to BambooHR's LinkedIn URL custom field or a text field configured during schema design. Gem's LinkedIn handle deduplication (returning a 400 error on duplicate linked_in_handle during create) is handled by querying existing candidates first and using update logic when a match is found; this does not apply in the BambooHR import direction but is noted for dual-system customers who maintain Gem as a read-only archive.
Gem
Project (Hired Employee Link)
BambooHR
Employee: Department / Job Opening
1:1Gem Projects group candidates by requisition or sourcing initiative. For hired candidates, we map the linked Project to the BambooHR Employee's department assignment and job opening reference. If the Project has a requisition identifier, we create a corresponding Job Opening in BambooHR and link the Employee to it. Projects without a hired candidate outcome are documented in the written handoff inventory rather than imported.
Gem
Sequence (Hired Candidates)
BambooHR
Not Migrated
1:1Gem Sequences define automated outreach cadences with multi-step messaging flows. BambooHR has no equivalent feature for recruiting sequences. Sequences do not migrate and are explicitly excluded from scope. We deliver a written inventory of active Sequences with their step definitions, A/B test configurations, and outreach timing for the customer's admin to document or rebuild in a dedicated sales engagement tool if needed.
Gem
Engagement: Emails (Hired Candidate)
BambooHR
Employee: Notes
1:manyGem stores email engagement history against Candidate records. For hired candidates, we map relevant email summaries (offer letters, onboarding confirmations, recruiter communications) to BambooHR Employee Notes. Full email body content transfers as note body text; timestamp and sender preserved. Marketing and recruiting outreach emails are not migrated unless specifically scoped as relevant to the employment relationship. Gem's activity history access depends on the Admin Compliance export scope.
Gem
User (Recruiter)
BambooHR
BambooHR Administrator or User
1:1Gem Users (recruiters and hiring managers) do not map to BambooHR Employees if they are not also employees of the company. We extract the user list and match by email against the BambooHR employee directory. Users without a matching BambooHR Employee record are flagged for the customer to provision separately. Gem user roles and permissions must be reconfigured in BambooHR's access control settings post-migration.

Migration approach
Discovery and scope definition
We audit the Gem workspace for candidate count by pipeline stage, active Sequences, active Projects, custom field definitions (name, type, reportability), and user accounts. We identify hired candidates via pipeline stage or a custom hired flag, extract work history and education sub-records, and inventory custom fields. We pair this with a BambooHR field audit to identify existing employee fields and custom field slots. The discovery output is a written migration scope that scopes Sequences out of scope by default and identifies whether the talent pool export is in scope or excluded.
Schema design and field-type validation
We design the BambooHR employee schema by mapping each Gem Candidate custom field to a typed BambooHR employee field. Single-select and multi-select fields in Gem map to BambooHR picklist fields only after we validate that Gem values match BambooHR picklist options. We pre-create any missing custom fields in BambooHR via the API, configure field visibility, and confirm with the customer's BambooHR admin before migration. Department and supervisor mapping uses BambooHR's standard org structure fields.
Candidate extraction and hired-candidate filtering
We export candidate records from Gem using Admin Compliance settings, applying the hired-candidate filter at extraction time. Work history and education sub-records are extracted as separate related-record sets. We build a candidate-to-employee transform that maps the primary contact fields (name, email, phone, address), sets the BambooHR hire date, and preserves the Gem candidate ID as a custom field for audit trail. The extraction emits a record-count report by status (hired, offer extended, active pipeline, talent pool) for customer review.
Sandbox import and reconciliation
We run a trial import into a BambooHR test environment using representative record volume. The customer's HR lead spot-checks 20-30 imported employee profiles against the Gem source, verifies work history accuracy, and confirms custom field values rendered correctly. Any field-type mismatches (drop-down values not matching, date formats) are corrected in the schema design phase before production import begins. This step validates that BambooHR picklist options are complete for all incoming custom field values.
Production migration and dependency order
We run production import in a single pass: Employee records with embedded work history and education sub-records via the BambooHR Employee API. Custom fields are set via the custom field API endpoint after base employee records are created. The Gem candidate ID is stored in a BambooHR custom field for reconciliation. Each import phase emits a row-count reconciliation report. Any records rejected due to picklist mismatches are captured in an exception report for the customer to resolve in BambooHR admin before a retry pass.
Cutover, validation, and sequence handoff
We freeze Gem write access for the migration window, run a final delta import of any candidate records updated since initial extraction, and deliver the written sequence and project inventory to the customer's HR admin. We support a three-day hypercare window where we resolve import exceptions and answer reconciliation questions. We do not rebuild Gem Sequences as BambooHR workflows; that work is documented separately and handled by the customer's admin team or a BambooHR implementation partner.
