Overview
Omni HR is an all-in-one HRIS built for the employee lifecycle — from recruitment through payroll — with multi-country compliance across 190+ countries. Recruit CRM is a candidate-centric recruitment and applicant tracking platform designed for staffing and executive search agencies, not internal HR teams. The fundamental mismatch is structural: Omni HR organizes data around Employees and their employment lifecycle, while Recruit CRM organizes around Candidates, Clients, and Job orders in a recruiter-centric pipeline. We resolve that schema gap during scoping by separating candidate records (sourced from Omni HR's Candidate and Onboarding objects) from employee records (sourced from Omni HR's Employee and Payroll objects) and mapping each to its equivalent Recruit CRM entity. Omni HR's 60 req/min API rate limit and lack of bulk export endpoints govern export throughput, so large datasets with multi-year histories extend migration windows measurably. Country-specific statutory fields (CPF, MPF, EPF) require explicit mapping to Recruit CRM's equivalent payroll or compliance fields, and we flag this during discovery rather than applying blind field-for-field mapping that would corrupt compliance data at the destination.

Object mapping
Each row shows how a Omni HR 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.
Omni HR
Employee
Recruit CRM & ATS
Candidate
1:1Omni HR Employee records map to Recruit CRM Candidate records. We map first name, last name, email, phone, location, employment status, and department. The Candidate record in Recruit CRM will carry the original employee status as a tag or custom field so the migration history is auditable. Manager assignments from Omni HR do not map to a native Recruit CRM field (no org chart object), so we flag these for manual re-entry or documentation.
Omni HR
Candidate (Recruitment)
Recruit CRM & ATS
Candidate
1:1Omni HR Candidate records are the cleaner migration source for Recruit CRM since both platforms treat candidates as first-class entities. We map candidate name, contact details, application stage, pipeline status, and any custom recruitment fields. Stage names from Omni HR are reconciled against Recruit CRM's pipeline stage values during scoping, with non-matching stages created as new pipeline stages in Recruit CRM before migration begins.
Omni HR
Company
Recruit CRM & ATS
Client
1:1Omni HR Company records (if used as part of recruitment or client tracking) map to Recruit CRM Client. The company name, address, and contact details migrate as Client fields. If Omni HR has no client-company records (typical for an internal HRIS), we skip this object and the customer starts Recruit CRM with an empty Client list to populate as they use the platform for new business.
Omni HR
Onboarding
Recruit CRM & ATS
Candidate (with task tracking)
1:manyOmni HR Onboarding task lists, document collection status, and checklist progress map to Candidate records in Recruit CRM with task-oriented custom fields or notes. E-signature metadata does not transfer. Completed onboarding tasks are recorded as Candidate status updates; the original onboarding checklist is preserved as a text summary attached to the Candidate record. Active pending onboarding tasks are flagged for manual follow-up at the destination.
Omni HR
Time Off
Recruit CRM & ATS
Not migrated (out of scope)
lossyRecruit CRM is a recruitment and applicant tracking platform, not a leave management system. Omni HR Time Off records — leave requests, accrual balances, and approval history — have no equivalent in Recruit CRM's object model. We do not migrate Time Off data. If the customer needs leave history preserved, we recommend exporting Omni HR Time Off records as a CSV archive and storing it outside Recruit CRM for compliance or audit purposes.
Omni HR
Payroll Runs
Recruit CRM & ATS
Not migrated (limited mapping)
lossyOmni HR payroll runs and statutory deduction records (CPF, MPF, EPF, and similar country-specific fields) have no native equivalent in Recruit CRM, which is not a payroll platform. Country-specific statutory fields require explicit mapping by the customer's HR team before any payroll-adjacent data is loaded. We export payroll history as a structured CSV with a country-awareness layer applied during export, and we flag which records require compliance review before import into any payroll-capable destination system.
Omni HR
Performance Reviews
Recruit CRM & ATS
Not migrated
lossyOmni HR Performance Review records — review cycles, ratings, and feedback text — have no equivalent object in Recruit CRM. Review history migrates as a Candidate note or a separate archived document if the review was tied to a specific employee who is also a candidate in the system. Rating scales and review cycle configuration are not transferable.
Omni HR
Document
Recruit CRM & ATS
Candidate attachment
1:1Employee documents (contracts, IDs, offer letters) stored as file attachments in Omni HR export as file content with filenames. We re-attach these to the corresponding Candidate record in Recruit CRM. File-to-Candidate linkage is re-established during import by matching the employee name and document type against the candidate record. Any e-signature metadata associated with a document does not transfer.
Omni HR
Expense
Recruit CRM & ATS
Not migrated
lossyOmni HR Expense records have no equivalent in Recruit CRM's recruitment-centric object model. We do not migrate expense submissions, approval status, or reimbursement data. This is a known limitation for any staffing agency that tracked candidate-related expenses (interview travel, relocation) in Omni HR; those records should be exported as a CSV archive separately.
Omni HR
Custom Fields
Recruit CRM & ATS
Candidate custom fields
1:1Omni HR custom fields defined at the workbook level export with their field definition metadata (name, data type, allowed values) alongside the stored values. We map these to Recruit CRM candidate custom fields using the same field name and data type where supported. Custom fields that use a data type not available in Recruit CRM are converted to the nearest equivalent (e.g., date stored as text becomes a text field with a migration note). Custom field schema is validated in Recruit CRM's sandbox before the full import.
Omni HR
Org Chart
Recruit CRM & ATS
Candidate (hierarchy note)
lossyOmni HR's organizational hierarchy — derived from manager assignments on Employee records — has no native Recruit CRM equivalent. We extract the reporting structure from Omni HR employee profiles and produce a written org-chart summary (as a CSV or document) that the customer's Recruit CRM admin can use as reference. The hierarchy cannot be reconstructed as linked records in Recruit CRM without a custom object implementation, which is outside standard migration scope.

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.
Omni HR gotchas
API rate limit of 60 req/min constrains bulk migration speed
No bulk export API — all records require individual paginated requests
Payroll data requires country-aware field mapping
Custom field definitions are workbook-scoped and not fully documented in the public API reference
Workflow configurations are not exportable via 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
Discovery and scoping
We audit the Omni HR portal for record counts across all objects (Employees, Candidates, Onboarding records, Time Off, Payroll runs, Documents, Custom Fields), confirm which objects have active records versus archives, and identify any country-specific payroll fields in use. We map the Omni HR object inventory against Recruit CRM's supported object model and identify which source objects migrate cleanly, which require transformation, and which are out of scope (Time Off, Expenses, Performance Reviews). The discovery output is a written migration scope with record counts, object mapping table, and a timeline estimate.
Data export with rate-limit handling
We extract data from Omni HR's API using paginated requests throttled to the 60 req/min ceiling. For each object, we run a two-step export: first the workbook schema for custom fields, then the data records with their custom field values resolved. We export documents as file content with filename metadata and reconstruct the employee-to-document linkage from the API response structure. Payroll records export with an explicit country tag applied to each record so that the statutory field context is preserved outside Recruit CRM's candidate object.
Data cleaning and deduplication
We deduplicate candidate records where the same person appears in both Omni HR's Candidate object and Employee object. We clean formatting inconsistencies in phone numbers, email addresses, and addresses using Recruit CRM's expected input format. We apply the country-awareness layer to payroll records and flag any records with missing required fields for customer review before import. Duplicate candidate records are merged with a preference for the Candidate object record as the authoritative source.
Schema pre-creation in Recruit CRM
Before importing any data, we create the necessary custom fields in Recruit CRM to receive Omni HR's custom field definitions. We validate that Recruit CRM supports the equivalent data type for each custom field, applying conversion rules where necessary. We configure pipeline stages in Recruit CRM to match Omni HR's recruitment stage names, creating any missing stages before migration. We do not create Client records unless Omni HR contains company records used for client tracking.
Staged import and reconciliation
We import records into Recruit CRM in dependency order: first Candidates (from Omni HR Candidate and Employee objects, deduplicated), then Documents attached to the correct Candidate records, then custom field values mapped to the pre-created Recruit CRM custom fields. Each import phase produces a row-count reconciliation report. We run a spot-check sample of 20-30 records against the Omni HR source to validate field-level accuracy before declaring the staging phase complete.
Cutover, delta migration, and delivery
We freeze writes in Omni HR during the final cutover window, run a delta export of any records modified during the migration window, import the delta into Recruit CRM, and produce a final reconciliation report. We deliver the payroll CSV archive (with country-aware field labeling), the org-chart summary document, and the workflow configuration inventory to the customer. We do not rebuild Omni HR workflows in Recruit CRM; that is a separate post-migration implementation step that we document and hand off.
