Overview
Moving from Darwinbox to Recruit CRM is a scoped migration from a full-lifecycle enterprise HCM suite to a recruitment-focused ATS and CRM. Darwinbox covers the complete employee lifecycle from hire to retire with modules for recruitment, onboarding, attendance, leave, payroll, and performance. Recruit CRM is built for recruitment agencies and in-house talent teams, centred on Candidates, Jobs, Clients, and Engagements. The HCM modules with no ATS equivalent (payroll, attendance punch logs, leave balances, performance reviews, engagement recognition) do not migrate as structured records; we flag them in a written inventory for manual handling or downstream HRIS integration. We resolve the Darwinbox Candidate-to-Recruit CRM Candidate mapping, preserve interview stage history, and document the workflow and automation rebuild scope that Recruit CRM's admin team will need to recreate.
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 Darwinbox object lands in Recruit CRM & ATS, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Darwinbox
Employee (Recruitment Module)
Recruit CRM & ATS
Candidate
1:1Darwinbox employee records created through the recruitment funnel map to Recruit CRM Candidate records. We extract candidate name, email, phone, current stage in the hiring pipeline, source channel, and any custom fields attached to the employee record in Darwinbox's recruitment module. The candidate's application-stage history (applied, screening, interview, offer, hired, rejected) migrates as a custom stage-history field or note in Recruit CRM since Recruit CRM tracks current stage but may not preserve a full multi-stage timestamp log without custom configuration.
Darwinbox
Job Posting (Recruitment Module)
Recruit CRM & ATS
Job
1:1Darwinbox job postings map to Recruit CRM Job records. The job title, description, location, employment type, department, and status (open, closed, on hold) migrate directly. Job board distribution settings and posting URLs from Darwinbox are documented as a text field in Recruit CRM since the destination job board integrations are configured separately in Recruit CRM's settings.
Darwinbox
Organisation / Client (Recruitment Module)
Recruit CRM & ATS
Client
1:1Darwinbox organisations created as hiring clients in the recruitment module map to Recruit CRM Client records. Client name, industry, location, primary contact name, and contact email migrate. If the Darwinbox tenant does not use the separate client management module and only stores client information inside job postings, we extract client details from the job records and create standalone Client records in Recruit CRM.
Darwinbox
Employee (Core HR)
Recruit CRM & ATS
Contact
1:1Darwinbox employee records that are not sourced through the recruitment funnel (existing employees being managed in core HR) can be created as Contacts in Recruit CRM if the customer's use case involves managing relationships with placed candidates or internal talent pool contacts. We map employee name, department, title, and email. This is a lookup mapping where the customer's Recruit CRM admin decides whether a Contact record is needed for each employee type.
Darwinbox
Custom Fields (Recruitment Module)
Recruit CRM & ATS
Custom Fields
lossyDarwinbox tenant-specific custom fields in the recruitment module (text, number, date, boolean, or predefined-list types) are not documented in the public API schema and must be introspected from the live Darwinbox tenant before migration. We extract the field registry during discovery and map each custom field to a Recruit CRM custom field of the matching type. Recruit CRM's API supports custom field search with filter types including equals, text, longtext, number, and date. The customer admin configures the Recruit CRM custom field schema before migration day.
Darwinbox
Engagement: Interview Notes and Feedback
Recruit CRM & ATS
Activity / Note
1:1Darwinbox interview schedules, interviewer feedback, and rating data stored as part of the recruitment workflow map to Recruit CRM Activity records or Notes attached to the Candidate. We extract interview date, interviewer name, feedback text, and any scoring values. Darwinbox interview stage transitions are preserved as activity timestamps with a custom field for stage status.
Darwinbox
User / Role
Recruit CRM & ATS
User
1:1Darwinbox user accounts with roles (admin, recruiter, hiring manager, employee) map to Recruit CRM User records. We extract user name, email, and role type and map them to Recruit CRM's user and permission model. Users without a matching Recruit CRM account are placed in a reconciliation queue for the customer's admin to provision before record import.
Darwinbox
Org Structure / Department
Recruit CRM & ATS
Department (custom field or tag)
lossyDarwinbox hierarchical org units and department assignments attached to employees do not have a direct Recruit CRM equivalent. We extract the org structure and map department names to a custom field or tag on the Candidate or Job record in Recruit CRM. The customer admin decides during scoping whether department data attaches to Candidates, Jobs, or both.
Darwinbox
Attendance Records
Recruit CRM & ATS
Not migrated
1:1Darwinbox attendance punch logs, shift policies, and attendance compliance data are HCM records with no equivalent in Recruit CRM's recruitment and placement data model. We do not migrate attendance data. If the customer requires attendance tracking post-migration, we recommend a dedicated attendance or HRIS integration configured separately in Recruit CRM or a complementary tool.
Darwinbox
Leave Balances
Recruit CRM & ATS
Not migrated
1:1Darwinbox leave types, accrual rules, and current leave balances are HCM records that do not map to Recruit CRM's ATS and CRM schema. We do not migrate leave balances. If the customer manages contractor or temp placement leave data in Recruit CRM, we can discuss a custom mapping as a separate scope item.
Darwinbox
Payroll / Compensation History
Recruit CRM & ATS
Not migrated
1:1Darwinbox payroll runs, compensation history with effective-dated salary rows, deductions, and tax codes are HCM records that do not have a place in Recruit CRM's candidate and placement data model. Compensation expectations stated by candidates (expected salary in Darwinbox) can be mapped to a custom field on the Candidate record in Recruit CRM as a lookup mapping, but historical payroll data does not migrate.
Darwinbox
Performance Reviews
Recruit CRM & ATS
Not migrated
1:1Darwinbox performance review cycles, ratings, goals, and manager feedback are HCM records that do not have an equivalent in Recruit CRM's ATS and CRM. We do not migrate performance data. If the customer uses Recruit CRM for talent advisory or executive search and wants to track candidate assessments post-placement, we can discuss a custom assessments custom field as a separate configuration item.

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.
Darwinbox gotchas
API access is privileged and request-only
Custom fields are tenant-specific and not in public schema
Attendance records require shift-policy alignment
Effective-dated compensation rows need careful sequencing
Document blobs are not accessible via public API
Recruit CRM & ATS gotchas
API rate limits are license-scaled and can throttle bulk migration
Custom field schemas vary per organization and require field-level mapping
Files and email attachments require separate extraction and re-upload
Email sequences and automation logic do not transfer between platforms
Pair-specific challenges
Migration approach
API access coordination and discovery
We initiate the Darwinbox API access request by coordinating with the customer's Darwinbox account owner and the [email protected] team. While access is pending, we extract tenant metadata via any available CSV exports, document the active recruitment modules in use (candidate pipeline stages, job posting types, custom fields visible in the UI), and build a preliminary object map. Discovery output is a written migration scope document listing every Darwinbox object we can migrate, every object with no Recruit CRM equivalent, and the data volume estimate for each migratable object.
Recruit CRM custom field configuration
We work with the customer's Recruit CRM admin to pre-create the custom field schema that mirrors the Darwinbox tenant's custom fields. Recruit CRM's API supports custom field creation with named filter types (equals, text, longtext, number, date). The admin creates these fields on the Candidate, Job, and Client objects before migration day. We validate the field list against the Darwinbox field registry during discovery and flag any Darwinbox field types that have no Recruit CRM equivalent for the customer to decide on a workaround (text field fallback, note attachment, or exclusion).
Data extraction and transformation
We extract data from Darwinbox in dependency order: Job records first (since client and candidate records depend on them), then Client records, then Candidate records with full pipeline stage history and custom field values, then Activity records (interview notes, feedback, communications) linked to the correct parent Candidate. We transform Darwinbox stage names to Recruit CRM stage values, map custom fields by name and type, and flag any records with missing required fields (for example, candidates without an email address) for the customer's review before loading.
Sandbox migration and reconciliation
We run a full migration into Recruit CRM's sandbox or a parallel test environment using production-like data volume. The customer's recruitment lead reconciles record counts (Candidates in, Jobs in, Clients in, Activities in), spot-checks 20-30 random candidate records against the Darwinbox source, and verifies that stage history, custom field values, and client assignments are correct. Any mapping corrections happen in this phase. We do not proceed to production migration without signed-off reconciliation from the customer's admin.
Production migration and cutover
We run production migration in record-dependency order: Jobs, Clients, Candidates, Activities. Each phase emits a row-count reconciliation report before the next phase begins. We freeze Darwinbox recruitment data writes during the cutover window, run a final delta migration of any records modified during the migration window, then enable Recruit CRM as the system of record for candidate tracking. User accounts are validated against the Recruit CRM user list and any missing users are provisioned by the admin before candidate records are assigned.
Handoff and workflow inventory delivery
We deliver the migration handoff package to the customer's Recruit CRM admin. The package includes the record-count reconciliation report, the Darwinbox workflow and approval chain inventory (for manual rebuild in Recruit CRM's workflow builder), the document export checklist (for manual handling of resumes and files not accessible via API), and the HCM module inventory noting what could not migrate. We support a five-day hypercare window where we resolve any data issues raised by the recruitment team. We do not rebuild Darwinbox workflows as Recruit CRM workflows inside the migration scope; that is a separate configuration engagement.
