Overview
Moving from Yello to Recruit CRM is an export-first migration because Yello does not publish a public API. We work from Yello's structured CSV downloads and manual data dumps, requesting explicit guidance from Yello support on how to generate a complete data export. We map Yello Candidates to Recruit CRM Candidates, Yello Requisitions to Recruit CRM Jobs, and Yello Events to Recruit CRM Events, with multi-day Events parsed into individual day records. Custom fields on both Candidates and Requisitions require a discovery pass against sample data before migration scoping because the field schema cannot be discovered programmatically. We preserve pipeline stage ordering, tagged Candidate groupings, and Evaluation scores throughout the transfer. Workflows, automation rules, and LinkedIn CRM Connect profile refresh settings do not migrate as configuration; we deliver a written inventory of any configured automations for the customer's admin to rebuild in Recruit CRM's workflow builder.
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 Yello 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.
Yello
Candidate
Recruit CRM & ATS
Candidate
1:1Yello Candidates map directly to Recruit CRM Candidates. We extract the full Candidate record including contact information, source attribution, pipeline stage, tags, and engagement history. Custom Candidate properties discovered during the discovery pass are mapped to equivalent Recruit CRM custom fields. Any Yello Candidate appearing across multiple Requisitions (duplicate detection) is flagged and reconciled before import to prevent Recruit CRM duplicate records.
Yello
Job Requisition
Recruit CRM & ATS
Job
1:1Yello Requisitions represent open positions with metadata including department, location, headcount, and status. They link to Candidates via a many-to-one relationship. We preserve this association by importing Jobs first, then resolving the Job reference when Candidates are imported so that the Candidate-to-Job linkage is maintained in Recruit CRM. Requisition status (Open, On Hold, Filled, Cancelled) maps to Recruit CRM Job status values.
Yello
Event
Recruit CRM & ATS
Event
lossyYello Campus Events spanning multiple days require flattening. The standard Yello export represents a multi-day Event as a single record with a date range. We parse the date range, split into individual day records, and write each as a separate Event in Recruit CRM. Event metadata (name, venue, description) and registration lists migrate as-is. Attendance records linking Candidates to Event days are preserved as Candidate Event participation entries in Recruit CRM.
Yello
Evaluation
Recruit CRM & ATS
Note (or Custom Evaluation Object)
lossyStructured Evaluation records in Yello include scores, comments, evaluator attribution, and the associated pipeline stage. Custom evaluation forms may use non-standard field names that require a field-mapping table before migration. We extract the evaluation body, score values, and evaluator name and write to Recruit CRM as either formatted Note records (for free-text evaluations) or as structured custom fields if the customer configures an evaluation object in Recruit CRM during discovery.
Yello
Note
Recruit CRM & ATS
Note
1:1Free-text conversation history and recruiter commentary attached to Candidates migrate as plain-text or HTML Notes in Recruit CRM. We extract the note body, author name, and timestamp and write as a Note record linked to the corresponding Candidate. The original author attribution is preserved in the Note body or a custom Note metadata field.
Yello
Tag
Recruit CRM & ATS
Tag / Label
1:1Flexible Candidate labels in Yello (typically used for school, degree, role, or recruiting season categorization) are extracted as a flat tag list. These are written to Recruit CRM as tag or label values attached to the Candidate record. Tag grouping and hierarchy are not preserved if Yello uses nested tag structures; we document the flat output and recommend manual grouping in Recruit CRM if needed.
Yello
Pipeline Stage
Recruit CRM & ATS
Pipeline Stage
lossyConfigurable hiring stage names and ordering are extracted from Yello including stage name, position in the sequence, and active/inactive status. Stage ordering is preserved in Recruit CRM by writing stages in ascending position order during the pipeline configuration pass. Any custom stage names (non-standard labels) are mapped to Recruit CRM stage equivalents or retained as-is if the destination allows custom stage names.
Yello
Attachment
Recruit CRM & ATS
Document
1:1Binary files associated with Candidates including resumes, cover letters, and portfolio items are extracted from Yello exports. We write each file blob with its original filename and MIME type to Recruit CRM's document or attachment object, preserving the Candidate-to-Document linkage. Large attachment archives may require batch processing and are scoped separately during discovery.
Yello
User
Recruit CRM & ATS
User
1:1Internal recruiter and admin user accounts are mapped from Yello user names and email addresses to Recruit CRM User records. We resolve users by email match against the destination org's user table. Any Yello user without a matching Recruit CRM account goes to a reconciliation queue for the customer's admin to provision before Candidate migration resumes. Role and permission parity is out of scope for the data migration.
Yello
Custom Fields
Recruit CRM & ATS
Custom Fields
lossyBoth Candidate-level and Requisition-level custom properties are audited during the discovery phase. We request sample Yello data exports and screenshots of all configured custom fields to build a complete field-mapping table covering field name, data type, and Recruit CRM target field. Custom fields missed during discovery will appear as unmapped blanks in Recruit CRM and require a correction pass. Recruit CRM supports custom fields on both Candidate and Job objects.

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.
Yello gotchas
No documented public API forces export-based migration
Custom field discovery must happen before migration scoping
Event multi-day structure requires flattening during export
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 export guidance
We audit the source Yello instance through structured CSV export requests and sample data pulls. We coordinate with Yello support to understand how to generate a full data export covering Candidates, Requisitions, Events, Evaluations, Notes, Tags, and Attachments. We request screenshots of all configured custom Candidate fields and custom Requisition fields. We document the pipeline stage configuration, the full custom field list, and the multi-day Event count to scope the migration correctly. The discovery output is a written migration scope, a data export checklist, and an initial field-mapping table for all standard fields.
Export extraction and data quality assessment
We receive the Yello data export and assess record counts, file formats, and completeness. We identify any gaps in the export (for example, missing Evaluations, truncated Attachments, or incomplete Event registration lists). We run duplicate detection across Candidate records to surface any Candidates appearing across multiple Requisitions. We flag any fields that cannot be mapped from the export format (for example, rich-text fields stored as HTML blobs, or date fields with ambiguous timezone encoding). The output is a data quality report and a revised field-mapping table covering standard and custom fields.
Custom field mapping and multi-day Event splitting
We build the complete field-mapping table covering every Yello field (standard and custom) and its Recruit CRM equivalent. For custom fields, we document the data type, sample values, and recommended Recruit CRM custom field configuration. We run the multi-day Event splitting logic against the Event export: each Yello Event with a date range is transformed into N individual day records before the Recruit CRM import. We validate the split output against the original registration lists to confirm attendance data integrity.
Recruit CRM import preparation
We prepare the Recruit CRM destination for import: creating any required custom fields on Candidate and Job objects, configuring pipeline stages to match Yello's stage ordering, and setting up the user mapping (resolving Yello user emails to Recruit CRM User records). We request the customer verify that all Recruit CRM Users required for the migration have been provisioned. We run a small-volume pilot import (first 100-200 records) to validate the mapping, catch any import errors, and confirm that Recruit CRM field validation rules do not reject records with non-standard data formats.
Production migration in dependency order
We run production migration in record-dependency order: Jobs (Requisition data) first so that Job IDs are available for Candidate linkage, then Candidates with their Requisition associations and Tags, then Notes and Evaluations linked to the migrated Candidates, then multi-day Events split into individual day records, then Attachments linked to their parent Candidates. Each phase emits a row-count reconciliation report showing records imported, records skipped, and records flagged for manual review. The customer reviews the reconciliation report and approves before the next phase begins.
Cutover, validation, and automation inventory handoff
We freeze Yello write access during the cutover window, run a final delta migration of any records modified during the migration window, then hand over to the customer's team for Recruit CRM go-live. We deliver a written inventory of any Yello automations, candidate progression rules, and communication triggers that do not migrate as configuration. The customer's admin rebuilds these in Recruit CRM's workflow builder using the inventory as a guide. We support a 72-hour hypercare window where we resolve any record-level reconciliation issues surfaced during the first days of Recruit CRM production use.
