Overview
Teams migrate from Zinc to Zoho CRM when their hiring and candidate operations grow beyond what a standalone referencing toolkit handles, and they need a full CRM to manage the downstream customer relationship after a candidate becomes a client. Zinc stores candidate profiles, reference checks, employment verifications, and background check results tied to a hiring workflow. Zoho CRM has no native background-check module — reference check data migrates into Tasks and custom fields on Leads, and the end-to-end referencing workflow has to be rebuilt with Zoho Blueprint and Deluge scripts. The migration carries all candidate records, reference contacts, verification dates, and check-status history into Zoho Leads and Tasks. The hard parts are mapping Zinc's reference-check sub-objects to Zoho Tasks with custom fields, preserving the check-type and outcome labels through pick-list value mapping, and sequencing the migration so new Zoho Leads resolve their Contact lookups before reference tasks attach. FlitStack uses the Zinc API and CSV export for staged extraction, validates field-level mapping with a sample run before committing the full dataset, and captures a 24–48 hour delta window for any records modified between extraction and go-live.

Object mapping
Each row shows how a Zinc object lands in Zoho CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Zinc
Candidate
Zoho CRM
Lead
1:1Zinc Candidate records map directly to Zoho CRM Leads. Each candidate becomes a Lead with the candidate name, contact details, and job-applied-for stored in standard Lead fields. If the candidate was already converted in a prior Zoho setup, the record routes to Contact instead.
Zinc
Candidate Email
Zoho CRM
Lead Email
1:1Candidate email in Zinc maps to the standard Email field on Zoho CRM Lead. This field serves as the primary lookup key for deduplication across the migration and is used to match reference contacts to their corresponding Zoho Lead record during the task linking phase. FlitStack validates email format before import to prevent validation errors in Zoho.
Zinc
Candidate Phone
Zoho CRM
Lead Phone
1:1Candidate phone number from Zinc migrates to the Phone field on Zoho Lead. Mobile numbers where available migrate to the Mobile field if Zoho has that field active on the Lead layout for the account. If Mobile is not enabled, it appends to the Phone field with a prefix indicator.
Zinc
Reference Check
Zoho CRM
Task + Custom Fields
1:1Each Zinc Reference Check becomes a Zoho Task linked to the Lead. Custom fields on the Task carry the reference contact name, relationship to candidate, check type, status, and outcome score. This preserves the check history without requiring a custom module.
Zinc
Reference Contact Name
Zoho CRM
Task Custom Field (Referee Name)
1:1Zinc stores the reference contact's name as a sub-field of the Reference Check. In Zoho, this becomes a custom text field (Referee_Name) on the Task. Must be created in Zoho before migration — field label becomes API name Referee_Name in camelCase.
Zinc
Check Status (Pending / Complete / Failed)
Zoho CRM
Task Status (Not Started / In Progress / Completed)
1:1Zinc check status values map to Zoho Task status values: 'Pending' → 'Not Started' or 'In Progress' depending on whether the check was initiated, 'Complete' → 'Completed', 'Failed' → 'Not Completed' with a custom flag. Value-by-value mapping required for accuracy.
Zinc
Check Type (Employment / Education / Criminal)
Zoho CRM
Task Custom Field (Check_Type)
1:1Zinc supports multiple check types per candidate, including employment verification, education verification, criminal background, and personal reference checks. Each type becomes a separate Task with Check_Type__c custom pick-list set to the source type value. Teams with three check types get three tasks per candidate in Zoho, linked to the same parent Lead.
Zinc
Verification Date
Zoho CRM
Task Due Date + Custom Field (Verified_Date)
1:1Zinc records the date a reference was completed as part of the check workflow. This date migrates to a custom datetime field Verified_Date__c on the Task to preserve the completion timestamp. Zoho's native Due Date is set to the check submission date, not the completion date, to preserve the workflow timeline for task scheduling purposes.
Zinc
Outcome Score / Rating
Zoho CRM
Task Custom Field (Check_Score)
1:1Zinc calculates or stores a reference score based on the reference response. This migrates as a custom numeric field Check_Score__c on the Task. If Zinc uses a 1–5 rating scale, the numeric value transfers directly. If it uses a descriptive rating, a pick-list is created in Zoho with the same values.
Zinc
Company / Employer Applied To
Zoho CRM
Lead Company Name
1:1The company or position the candidate applied to in Zinc maps to the Company Name field on the Zoho Lead. This field is searchable and used for Lead segmentation by hiring department, enabling recruiters to filter candidates by target employer or job function within Zoho reports.
Zinc
Submitted By (Recruiter)
Zoho CRM
Lead Owner
1:1Zinc records which recruiter or team member submitted the candidate record for background checking. Owner resolution in Zoho matches the submitting user's email to an active Zoho user account. Unmatched owners are flagged in the pre-flight report and assigned to a fallback user before migration commits to prevent orphaned records.
Zinc
Candidate Created Date
Zoho CRM
Lead Original_Created_Date__c
1:1Zoho's native CreatedDate is set at migration execution time and reflects when the record enters Zoho. The original candidate creation timestamp from Zinc is preserved in a custom datetime field Original_Created_Date__c to maintain reporting continuity on hiring velocity and candidate aging metrics post-migration.
Zinc
Source System ID
Zoho CRM
Lead Source_System_ID__c
1:1Zinc's internal candidate ID is stored as Source_System_ID__c on the Zoho Lead for full traceability across migration runs, delta-run deduplication to prevent duplicate records, and complete audit trail if a correction run is needed to reconcile any data discrepancies discovered after initial migration.
Zinc
Attachment (Resume / PDF Report)
Zoho CRM
Attachments on Lead
1:1Zinc file attachments including PDF reports, resume uploads, and verification documents re-upload to Zoho CRM as Attachments on the Lead record. Zoho's per-file size limit is 10 MB for Standard plans and 25 MB for higher tiers. Large PDF reports may require compression before upload to comply with size restrictions.

Migration approach
Audit Zinc schema and export data in staged CSV batches
FlitStack reads the Zinc API to enumerate all Candidate fields, Reference Check sub-object fields, check types, and custom fields. We export candidate records in batches by status (Active, Hired, Rejected) to manage volume. Reference check records are exported separately and linked to their parent candidate by the Zinc candidate ID before transformation begins. The export also captures attachment URLs for re-upload to Zoho.
Set up Zoho schema: custom fields, pick-list values, and task layout
Before any data moves, FlitStack creates all required custom fields in Zoho CRM via the Settings > Fields API: Check_Type__c, Referee_Relationship__c, Check_Score__c, Verified_Date__c, Source_System_ID__c, Report_Link__c, Hired_Date__c, Response_Time_Hours__c on the Task module, and custom fields on Lead for background-check-specific data. Pick-list values for check type, relationship, and status are synchronized from the Zinc schema to ensure no validation errors during import.
Resolve owner and user records by email match
Zinc records include a submitted-by user (recruiter). FlitStack matches each unique recruiter email against active Zoho users via the GET /users endpoint. Matched users are assigned as Lead Owner. Recruiters with no Zoho account are flagged in the pre-flight report — your team either creates their Zoho user account before migration or assigns those records to a fallback owner. No Lead lands in Zoho without a resolvable owner.
Run a sample migration with field-level diff
A representative slice of 50–100 candidates — spanning Active, Hired, and Rejected statuses, with mixed check types and varying owner assignments — migrates to a Zoho sandbox or staging org first. FlitStack generates a field-level diff comparing each Zinc field value against the mapped Zoho field value, flagging any pick-list mismatches, truncated text, or missing lookups before the full run commits.
Execute full migration with delta-pickup window
Full migration runs against the production Zoho org with Leads created first, then Tasks linked by Lead ID. A 24–48 hour delta-pickup window captures any new candidates or updated reference checks that were modified in Zinc during the cutover window. All operations are logged to an audit CSV. One-click rollback reverts Zoho to the pre-migration snapshot if reconciliation fails. After validation, FlitStack delivers a migration summary with record counts by module, error log, and owner resolution report.
