Overview
Moving from Mosaic HCM to Recruit CRM is a platform-category migration: Mosaic HCM is a full HCM suite with a built-in recruiting module, while Recruit CRM is a dedicated ATS and recruitment CRM for staffing agencies and executive search firms. The migration scope centers on talent acquisition data—candidates, applications, jobs, client contacts, and pipeline stages—rather than the full HRMS stack (payroll, benefits, time entries). Mosaic HCM does not offer self-service API access; all data exports require professional services coordination with a 4-6 week lead time. We open the data request on day one of scoping to keep the timeline on track. Recruit CRM stores candidates and clients as separate objects with a one-to-many relationship, while Mosaic HCM stores candidate records within its unified employee schema. We split the two record types during extraction and load them into Recruit CRM's typed objects. Workflows, automations, and approval chains do not migrate; we deliver a written inventory of every active configuration for the customer's admin to rebuild in Recruit CRM's automation builder.

Object mapping
Each row shows how a Mosaic HCM 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.
Mosaic HCM
Candidate / Applicant Records
Recruit CRM & ATS
Candidate
1:1Mosaic HCM's ATS module stores candidate records with application status, source, and associated job postings. We extract all active and recently inactive candidates and map them to Recruit CRM's Candidate object. The candidate's email address is the dedupe key; we resolve duplicates by email match and flag records with the same name and email for manual reconciliation before load.
Mosaic HCM
Job Requisitions / Postings
Recruit CRM & ATS
Job
1:1Open and recently closed job postings in Mosaic HCM map to Recruit CRM's Job object. Fields including job title, department, location, employment type, and job description transfer directly. We preserve the original posting date and any internal job ID from Mosaic HCM as a custom field for audit traceability. Closed jobs more than 90 days past close date are archived rather than migrated unless the customer explicitly requests them.
Mosaic HCM
Applications / Candidate-Job Association
Recruit CRM & ATS
Application
1:1The association between a candidate and a job posting in Mosaic HCM maps to Recruit CRM's Application object. Application status (applied, screening, interview, offer, hired, rejected) maps to Recruit CRM's pipeline stage values. We resolve the parent Candidate and Job references at migration time using email-based and job-title-based lookups respectively.
Mosaic HCM
Employee Record (for active internal recruits)
Recruit CRM & ATS
Candidate
lossyMosaic HCM stores internal candidates (current employees applying to new roles) as employee records. We flag these during extraction and map them as internal candidates in Recruit CRM with an internal_candidate flag. Their existing Mosaic HCM employee ID is preserved as a custom field for any future HCM sync.
Mosaic HCM
Client / Hiring Organization
Recruit CRM & ATS
Client
1:1Mosaic HCM's organizational records for external hiring clients map to Recruit CRM's Client object. Client name, primary contact, industry, and location transfer directly. If Mosaic HCM stores client records as Company or Organization records without a client-specific type, we use the organization's address domain to classify external clients versus internal entities.
Mosaic HCM
Custom Candidate Fields
Recruit CRM & ATS
Custom Fields on Candidate
lossyMosaic HCM builds custom fields during implementation—skills taxonomies, source tracking fields, assessment scores, or consent flags. We enumerate every custom candidate property during the discovery session and create equivalent custom fields in Recruit CRM before migration. Recruit CRM supports custom fields on the Candidate object via its field management interface; we configure these in the destination org before loading data.
Mosaic HCM
Email Templates and Candidate Communications
Recruit CRM & ATS
Email Templates
1:1Candidate-facing email templates from Mosaic HCM's talent module export as text or HTML files. We import these into Recruit CRM's Email Templates library, preserving merge fields as Recruit CRM-compatible tokens. We do not migrate automated sequence emails; these are documented as a separate scope for Recruit CRM's automation rebuild.
Mosaic HCM
Documents / Files (Offer Letters, I-9s)
Recruit CRM & ATS
Attachments on Candidate
1:1Employee documents (offer letters, signed agreements, assessment results) stored in Mosaic HCM's document repository are extracted as files and associated with the correct candidate record in Recruit CRM. File naming preserves the original document type and date. We use Recruit CRM's file upload API to attach documents to the corresponding Candidate record after the base record is loaded.
Mosaic HCM
Benefits Enrollment (for compliance records)
Recruit CRM & ATS
Not migrated to Recruit CRM
1:1Benefits enrollment data (medical, dental, vision, 401k elections, dependent information) is HRMS-specific and has no place in a recruitment ATS. We do not migrate benefits data. If the customer's compliance team requires a benefits enrollment history for audit purposes, we export the data as a standalone file and deliver it separately from the ATS migration scope.
Mosaic HCM
Configurable Workflows (onboarding, approval chains)
Recruit CRM & ATS
Not migrated
lossyMosaic HCM's configurable workflow engine automates recruiting steps, approval chains, and task routing. These workflows are platform-specific and do not export as data. We document every active workflow—its trigger, conditions, and actions—during discovery and deliver a written inventory with recommended Recruit CRM automation equivalents. The customer's admin rebuilds them in Recruit CRM's workflow builder post-migration.

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.
Mosaic HCM gotchas
No direct customer API access for self-service exports
Custom fields and configurations are invisible without discovery sessions
Multi-EIN data requires entity-splitting before destination load
Historical payroll data requires elevated access and lead time
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
Open Mosaic HCM data request and scope discovery
On day one of migration scoping, we open a formal data request with Mosaic HCM's professional services or support team. Simultaneously, we run a structured discovery session with the customer's Mosaic HCM administrator to enumerate every custom field, workflow, and configuration in use. We extract a schema inventory covering candidate properties, job fields, application status values, and document types. We also identify the EIN structure for multi-entity customers and confirm which legal entities are in scope for migration.
Deduplication and data quality pre-clean
We run a three-pass deduplication against the Mosaic HCM candidate export: exact email match, fuzzy name match (Levenshtein distance), and phone number match. Duplicate candidates are flagged in a reconciliation report delivered to the customer's recruiter lead for manual resolution before load. We also standardize date formats (ISO 8601), normalize state and country codes, and strip any formatting artifacts from phone numbers and addresses to match Recruit CRM's field validation requirements.
Entity split and schema mapping
For multi-EIN customers, we split the candidate export by EIN and map each entity to the appropriate Recruit CRM subscription or custom entity tag. We configure Recruit CRM's custom fields to match every enumerated Mosaic HCM custom property before any data load. Recruit CRM field types are set to match the source (text, number, date, picklist) to prevent validation rejection. The Client and Job object schemas are configured in parallel with the Candidate schema.
Sandbox import and reconciliation
We run a full migration into Recruit CRM's staging or sandbox environment using production-equivalent record volumes. The customer's recruiter lead validates candidate counts by status, spot-checks 20-30 random records against the Mosaic HCM source, and confirms that custom field values transferred correctly. Any mapping corrections are documented and applied before the production migration begins.
Production migration in dependency order
We run production migration in record-dependency order: Jobs first (since Applications reference them), then Clients, then Candidates, then Applications (with parent Candidate and Job references resolved). Documents are attached to Candidate records after base records are loaded. Each phase emits a row-count reconciliation report before the next phase begins. We use chunked batch submission to Recruit CRM's REST API with exponential backoff on rate-limit responses.
Cutover, validation, and workflow handoff
We freeze Mosaic HCM recruiting writes during the cutover window, run a final delta migration of any records created or modified during migration, then enable Recruit CRM as the system of record. We deliver the workflow inventory document to the customer's admin team with a Recruit CRM automation rebuild guide. We support a five-business-day hypercare window to resolve any data issues raised by the recruiting team. Workflow rebuild, sequence setup, and admin training are outside the migration scope and are handled by the customer's internal team or a Recruit CRM implementation partner.
