Overview

What this migration involves

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.

Why teams make this switch

Two sides of the same decision

Leaving

Mosaic HCM logo

Mosaic HCM

What's pushing teams away

  • No self-service API or direct customer access — every data export requires a Mosaic professional-services ticket, which creates 4-6 week lead times that frustrate data-engineering teams.
  • Pricing is fully custom and bundled with Mosaic's managed services — comparison shopping against alternatives like Rippling, Paylocity or ADP Workforce Now is hard without engaging sales.
  • UKG Ready's product cadence is slower than newer cloud HCMs; customers report waiting for feature gaps to close, particularly in scheduling and modern UI/UX.
  • Complex union or rules-based scheduling environments hit UKG Ready scheduler limitations; healthcare and unionised workforces frequently outgrow the platform.
  • Mosaic-specific configurations (custom fields, workflow logic) are not portable to other UKG resellers or platforms, creating switching cost when customers consider leaving.

Choosing

Recruit CRM & ATS logo

Recruit CRM & ATS

What's pulling them in

  • Agencies choose Recruit CRM for its full customizability — pipelines, stages, and fields can be tailored to any recruitment workflow without developer involvement.
  • Small teams value the built-in CRM and ATS combined in one subscription, eliminating the need to purchase and sync separate systems.
  • The Chrome extension for one-click LinkedIn profile collection streamlines candidate sourcing and reduces manual data entry for recruiters.
  • Responsive customer support with fast issue resolution is consistently cited as a reason teams stick with the platform long-term.
  • Automation options including email sequences and workflow triggers allow recruitment agencies to reduce repetitive manual outreach tasks.

Object mapping

How Mosaic HCM objects map to Recruit CRM & ATS

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

maps to

Recruit CRM & ATS

Candidate

1:1
Fully supported

Mosaic 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

maps to

Recruit CRM & ATS

Job

1:1
Fully supported

Open 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

maps to

Recruit CRM & ATS

Application

1:1
Fully supported

The 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)

maps to

Recruit CRM & ATS

Candidate

lossy
Fully supported

Mosaic 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

maps to

Recruit CRM & ATS

Client

1:1
Fully supported

Mosaic 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

maps to

Recruit CRM & ATS

Custom Fields on Candidate

lossy
Fully supported

Mosaic 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

maps to

Recruit CRM & ATS

Email Templates

1:1
Fully supported

Candidate-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)

maps to

Recruit CRM & ATS

Attachments on Candidate

1:1
Fully supported

Employee 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)

maps to

Recruit CRM & ATS

Not migrated to Recruit CRM

1:1
Fully supported

Benefits 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)

maps to

Recruit CRM & ATS

Not migrated

lossy
Fully supported

Mosaic 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.

Pair-specific challenges

  • Mosaic HCM requires professional services for any data export

    Mosaic HCM does not publish API credentials or a self-service export portal. All candidate records, job postings, and application data must be pulled by Mosaic HCM's implementation or support team. We open the data request on day one of scoping and build in a 4-6 week lead time for them to prepare and deliver the export in a usable format (typically CSV or Excel). This lead time extends the overall migration schedule compared to platforms with open APIs. If the customer has multiple EINs, we explicitly request that the EIN field is included in every export record; Mosaic HCM's default export may bundle employees without entity tags.

  • Multi-EIN organizations must resolve entity split before migration

    Many Mosaic HCM customers run multiple legal entities (EINs) on a single database instance. Recruit CRM operates on a single-entity-per-subscription model. We extract the EIN field from Mosaic HCM's export and either consolidate all candidates under a single Recruit CRM instance or advise the customer to purchase separate Recruit CRM subscriptions per entity. If consolidation is chosen, we tag each candidate record with a custom entity field derived from the EIN. Misassignment at this step causes compliance and billing issues downstream.

  • Duplicate candidate records require deduplication before load

    Candidate databases in HCM platforms often accumulate duplicates over years of recruiting activity—same person with different email addresses, slight name variations, or multiple applications across job postings. Recruit CRM has built-in duplicate candidate prevention, but pre-migration deduplication reduces the number of records rejected or quarantined during bulk import. We run a three-pass dedupe (exact email, fuzzy name match, phone number) against the Mosaic HCM export and deliver a reconciliation report to the customer's recruiter lead for manual resolution of ambiguous cases.

  • Recruit CRM's API rate limits require batch chunking for large imports

    Recruit CRM's REST API enforces per-minute and per-day rate limits for bulk data operations. Migrations with over 5,000 candidate records or 2,000 applications require chunked batch submission with retry logic. We use exponential backoff on 429 responses and chunk requests into batches of 200 records per POST call. The migration runbook documents the chunk size and retry policy for the customer's IT team to reference during validation testing.

  • Workflows and automations are not transferable between platforms

    Mosaic HCM's configurable recruiting workflows and Recruit CRM's automation builder are architecturally incompatible. Workflows, approval chains, and automated task routing cannot migrate as code. We deliver a written workflow inventory with every active Mosaic HCM automation enumerated (trigger, conditions, actions, owner) and a field-by-field mapping to Recruit CRM's automation equivalents. The customer's admin or a Recruit CRM partner rebuilds them post-migration. This is explicitly out of scope for the data migration engagement.

Migration approach

Six steps for a successful Mosaic HCM to Recruit CRM & ATS data migration

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

Platform deep dives

Context on both ends of the pair

Source

Strengths

  • Single-database architecture means all HCM modules share one schema—no integration gaps between payroll, HR, and time.
  • Multi-EIN functionality lets organizations with multiple legal entities manage all entities on one platform instance.
  • SSAE 16 SOC 1 Type II and SOC 2 Type II certifications cover security, availability, and confidentiality controls.
  • API-first architecture with hundreds of documented third-party integrations via the UKG Ready ecosystem.
  • Responsive mobile UI provides consistent experience across employee, manager, and admin-facing surfaces.

Weaknesses

  • No public-facing API documentation for customers; all data exports require Mosaic HCM professional services coordination.
  • Pricing is fully custom and not published, making cost comparison during migration planning difficult.
  • Customizations built during implementation are scoped to Mosaic HCM's configuration and may not transfer to other platforms.
  • UKG Ready scheduling capabilities have known limitations for complex union or rules-based scheduling environments.
  • Product development cycle is slow, leaving feature gaps that customers work around with spreadsheets.

Most migrations land between six and eight weeks for organizations with under 5,000 candidate records and a single EIN. The primary timeline driver is Mosaic HCM's professional services coordination for the data export, which typically requires 4-6 weeks of lead time before extraction begins. Multi-EIN organizations or databases exceeding 20,000 candidate records extend to ten to fourteen weeks because of entity-splitting work, deduplication scope, and Recruit CRM bulk import validation cycles.
