Overview
Moving from E-Staff to Crelate is a platform-type migration: E-Staff functions as an HRMS with staffing-specific objects (Candidates, Placements) alongside standard HR records, while Crelate is a modern ATS and CRM built around Contacts, Companies, and Opportunities. We resolve that structural difference by mapping E-Staff Candidates to Crelate Contacts and E-Staff Placements to Crelate Opportunities, with the placement-company relationship preserved as a Crelate Company lookup. Effective-dated compensation rows from E-Staff migrate as independent Opportunity line items or custom date-stamped fields rather than a single current value, maintaining the audit trail staffing agencies require. E-Staff custom fields, which lack enforced naming conventions, are audited and explicitly mapped before any data moves. Workflows, automations, and payroll integrations do not migrate; we deliver a written inventory of these for the customer's admin to rebuild in Crelate or retire.
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.

Object mapping
Each row shows how a E-Staff object lands in Crelate, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
E-Staff
Candidate
Crelate
Contact
1:1E-Staff Candidates map to Crelate Contacts. The candidate name, email, phone, address, and resume URL fields migrate as typed Contact fields. E-Staff candidate status (active, passive, placed, etc.) maps to a Crelate custom picklist field candidate_status__c. Candidate source and tags from E-Staff migrate as multi-select picklist fields on Contact. We preserve the original E-Staff candidate ID in a custom field estaff_id__c for reconciliation.
E-Staff
Company
Crelate
Company
1:1E-Staff Companies (client organizations in the staffing context) map directly to Crelate Companies. Company name, address, industry, and contact email migrate as typed Company fields. The estaff_id__c custom field is set on the Company for reconciliation. If E-Staff stores multiple contacts per company, the additional contacts migrate as Crelate Contacts linked via the Company lookup.
E-Staff
Placement
Crelate
Opportunity
1:manyE-Staff Placements are the central staffing object linking a Candidate to a Client Company with pay rate, bill rate, start date, end date, and job title. We map Placements to Crelate Opportunities with the Contact (candidate) as the primary WhoId and the Company (client) as the WhatId. Job title, position description, and staffing type (temp, temp-to-hire, direct-hire) migrate to custom Opportunity fields. E-Staff Placements that span multiple roles for the same candidate-company pair generate separate Opportunity records.
E-Staff
Effective-dated Compensation (Placement row)
Crelate
Custom Date-Range Fields or Opportunity Line Items
lossyE-Staff stores pay rate and bill rate as date-stamped rows with effective start and end dates, meaning the same field holds multiple historical values. We model these as Crelate custom fields with a date range suffix (pay_rate_effective_2024_01_01__c) or as individual Opportunity custom fields capturing the most recent compensation pair. The customer chooses the strategy during scoping. We flag any placement with more than three effective-dated rows as a complexity item and document the full history in the migration notes.
E-Staff
Job Order
Crelate
Opportunity or Job custom object
lossyE-Staff Job Orders (open requisitions) map to Crelate Opportunities with a job_order__c flag, or to a custom Job object if the customer uses Crelate's custom object capability. Job Order status (open, filled, cancelled) maps to Opportunity Stage. Open submissions in E-Staff become Crelate Activities (Tasks) on the related Opportunity.
E-Staff
Submission
Crelate
Task or Activity
1:1E-Staff Submissions (candidate submitted to a job order) map to Crelate Tasks linked to the Opportunity. Submission status (submitted, interview, offer, rejected) migrates as a custom picklist field submission_status__c. Submission notes and feedback from the hiring manager migrate as Task description and custom comment fields.
E-Staff
Employee (HR records)
Crelate
Contact or custom Employee object
lossyE-Staff HR records (standard employee profile fields beyond staffing contact info) map to Crelate Contacts with a department__c, hire_date__c, and employee_id__c custom field set. If the staffing agency runs concurrent HR operations, we recommend a custom Employee object in Crelate to separate HR and candidate data. If E-Staff stores payroll history, we migrate the current pay rate and last-pay-date as Contact custom fields and flag payroll data for the customer's payroll system admin to reconcile separately.
E-Staff
User or Recruiter
Crelate
User
1:1E-Staff recruiter and admin user accounts map to Crelate Users by email match. We resolve estaff_owner_id references on Candidate, Placement, and Company records to the corresponding Crelate User. Any E-Staff user without a Crelate match goes to a reconciliation queue for the customer's admin to provision before record import resumes.
E-Staff
Engagement: Notes
Crelate
Note
1:1E-Staff notes attached to Candidate, Placement, or Company records migrate to Crelate Note records linked via ContentDocumentLink to the parent Contact, Opportunity, or Company. Note body and timestamp preserve. If notes contain HTML formatting from E-Staff, we strip to plain text during transform to avoid Crelate rendering issues.
E-Staff
Engagement: Activities (calls, emails, meetings)
Crelate
Task and Event
1:1E-Staff engagement history (call logs, email threads, meeting records) attached to Candidates or Placements migrates to Crelate Tasks (TaskSubtype = Call for calls) and Events. We resolve the parent Contact and Opportunity references at migration time using the contact_id and placement_id lookups. ActivityDate and Duration preserve for timeline ordering.
E-Staff
Custom Field (user-defined)
Crelate
Custom Field
lossyE-Staff custom fields carry no enforced naming convention and may have inconsistent types across records. We audit every distinct custom field during scoping, resolve its data type (text, number, date, currency, picklist), and create a matching Crelate custom field on the appropriate Core Record before migration. Custom fields with mixed data types in E-Staff (a known E-Staff behavior) are flagged as data-quality items and mapped to Crelate text fields to avoid import rejection. The full custom field inventory is delivered as a written document at scoping.
E-Staff
Tag or Category
Crelate
Multi-Select Picklist
lossyE-Staff tags and categories used to classify Candidates and Placements migrate to Crelate multi-select picklist fields on Contact and Opportunity. Tag values that do not yet exist in Crelate are created during migration. If tags exceed 500 distinct values, we recommend a Crelate Topic-based tagging strategy instead.

Migration approach
Discovery and schema audit
We audit the full E-Staff data inventory via CSV export: every Candidate, Company, Placement, Job Order, Submission, and User record. We catalog every distinct custom field (field name, data type, record count, null rate), identify placement complexity (number of effective-dated compensation rows per Placement), and count engagement records per candidate. We pair this with a Crelate target schema design: Core Record custom fields, Opportunity staffing fields, and any custom objects required. The discovery output is a written migration scope, custom field inventory, and object mapping document signed off by the customer's operations lead.
Custom field creation and Opportunity configuration in Crelate
We create every mapped custom field in Crelate under Settings > Core Records before any data import. Staffing-specific Opportunity fields (pay_rate__c, bill_rate__c, start_date__c, end_date__c, placement_type__c) are configured as part of a custom Opportunity record type scoped to the staffing workflow. We set up the picklist values for placement_status__c, candidate_status__c, and submission_status__c to match E-Staff's status taxonomy. Custom field creation happens in Crelate's Settings before migration begins so that the Crelate API accepts the mapped field names during import.
Sandbox migration and reconciliation
We run a full migration into a Crelate sandbox environment (or a trial org if no sandbox is available) using production-like data volume. The customer spot-checks 25-50 random records across Contact, Company, Opportunity, and Activity, verifying field values against the E-Staff source. Any mapping corrections are documented and applied before production migration. The sandbox sign-off is the gate for proceeding to production. Effective-dated compensation handling is validated here, specifically checking that historical pay and bill rate values are preserved per the agreed strategy.
User reconciliation and Crelate User provisioning
We extract every distinct E-Staff recruiter and admin user referenced on Candidate, Placement, and Company records and match by email against Crelate Users. Any E-Staff owner without a matching Crelate User goes to a reconciliation queue. The customer's Crelate admin provisions missing Users (active status matching the E-Staff user's active/inactive flag). Owner resolution must be complete before any record import because OwnerId is required on Opportunity and Task.
Production migration in dependency order
We run production migration in dependency order: Companies (from E-Staff Company records), Contacts (from E-Staff Candidates with CompanyId resolved), Opportunities (from E-Staff Placements with ContactId and CompanyId resolved and staffing custom fields populated), Job Orders (as Opportunities with job_order__c flag), Submissions (as Tasks linked to Opportunities), effective-dated compensation (as date-suffixed custom fields per the agreed strategy), Activities (Tasks and Events via Crelate API), and Notes (via ContentDocumentLink). Custom field data is sanitized for encoding and HTML before each batch insert.
Cutover, delta sync, and automation handoff
We freeze E-Staff writes during the cutover window, run a delta migration of any records created or modified during the migration window, then mark Crelate as the system of record. We validate opportunity and candidate counts match between E-Staff and Crelate before the go-live call. We deliver the E-Staff automation and workflow inventory document to the customer's admin team with Crelate Automation rebuild recommendations. We support a one-week hypercare window for reconciliation issues. We do not rebuild E-Staff automations, sequences, or forms inside the migration scope; those are separate rebuild or retirement tasks.
