Overview
Moving from LogicMelon to Crelate is a structural migration that maps a multi-posting aggregator's data model onto a native ATS-CRM platform. LogicMelon stores candidate responses as unified Application records; Crelate separates Candidates (person records) from Applications (submission records against a Job). We split each LogicMelon Application into a Crelate Contact and a linked Application, preserving the original job reference throughout. Job board targeting lists are stored per job in LogicMelon rather than as global templates; we carry these as tags on each Crelate Job so teams can see the original posting distribution without re-executing the multi-post. CV documents are binary file attachments in LogicMelon; we extract and attach the raw file to the Crelate Contact record, treating structured profile fields as the primary data and the CV as the backup-of-record. Crelate offers a native LogicMelon integration for job distribution post-migration, but the integration does not move historical data—we handle the historical migration separately.

Object mapping
Each row shows how a LogicMelon 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.
LogicMelon
Job
Crelate
Job
1:1LogicMelon Job records map directly to Crelate Job. The job title, description, location, employment type, salary range, and posting schedule migrate as typed fields on the Crelate Job. We preserve the original LogicMelon job board target list as a comma-separated tag on the Crelate Job labeled 'Original Board Distribution' so teams can see which boards originally received each advert without re-executing the multi-post. The job's posting status (draft, active, paused, closed) maps to Crelate's job_status field.
LogicMelon
Application
Crelate
Candidate (Contact)
1:manyLogicMelon Application records contain both candidate profile data and application metadata. We split each Application into a Crelate Contact (the candidate person record) and a Crelate Application (the submission record). Contact fields include name, email, phone, address, work history, skills, and desired salary sourced from LogicMelon's structured profile. The original LogicMelon Application ID is preserved in a custom field on the Crelate Contact as a migration reference key.
LogicMelon
Application
Crelate
Application
1:manyThe application-side of the split maps to Crelate's Application record linked to the corresponding Job and Contact. The original application status (Applied, Screened, Interviewed, Offered, Placed, Rejected) maps to Crelate's application status field, and any LogicMelon screening notes, scores, or rating fields migrate to custom fields on the Crelate Application record. The application date and last-modified date migrate as typed date fields for timeline accuracy.
LogicMelon
Candidate / CV
Crelate
Contact with Resume attachment
1:1LogicMelon Candidate profiles include structured fields (name, email, phone, work history, skills, education) plus a CV file attachment. We migrate the structured fields directly to Crelate Contact fields and extract the CV document (PDF or Word) as a file attachment linked to the Contact. Any candidate data already captured in LogicMelon's structured profile fields takes priority; the CV file serves as the source-of-truth backup for records where structured fields are incomplete.
LogicMelon
Screening Notes
Crelate
Notes / Activity Form fields
1:1Recruiter notes and screening scores attached to LogicMelon Applications are migrated as notes on the Crelate Application record. Where LogicMelon uses structured rating fields (numeric scores or stage-based evaluations), we map these to Crelate custom fields on the Application object so they are searchable and reportable post-migration.
LogicMelon
Pipeline Stages
Crelate
Application Status values
lossyLogicMelon's configurable pipeline stages (Applied, Screened, Interviewed, Offered, etc.) are mapped to Crelate's Application Status picklist values during migration. We identify the customer's active stage names during discovery and configure matching status values in Crelate before the Application import phase, flagging any stages that do not have a direct Crelate equivalent for admin decision.
LogicMelon
Job Board Target List
Crelate
Tag on Job record
1:1LogicMelon stores the list of targeted job boards per job advert rather than as a global posting template. We preserve this board-association list as a tag on the Crelate Job record. Each board name in the original list becomes a separate tag so teams can filter jobs by original distribution channel. The tag is informational; Crelate's native job distribution (including its LogicMelon integration) handles ongoing posting rather than replicating the original board list directly.
LogicMelon
User (Recruiter)
Crelate
User
1:1LogicMelon Users tied to Applications and Jobs are mapped by email to Crelate User records. We export the user assignment on each record during extraction and resolve by email against the destination Crelate tenant's User table during import. Users without a matching Crelate User are placed in a reconciliation queue for the customer's admin to provision before the final import phase.
LogicMelon
Organisation
Crelate
Organisation or Company
1:1LogicMelon's multi-tenant organisation hierarchy (agency-level vs. client-level structures) is mapped to Crelate's Organisation or Company objects depending on whether the structure represents the recruiting agency itself or client organisations. We extract the hierarchy during discovery and configure the appropriate Crelate data model before data import.
LogicMelon
Custom Fields (Job)
Crelate
Custom Fields on Job
1:1LogicMelon custom fields on Job records are identified during discovery and mapped to Crelate Job custom fields. We create the destination custom field in Crelate (with matching field type where possible: text, number, picklist, date) before the Job import phase. Fields with value types that Crelate does not support are flagged for admin decision on fallback handling.
LogicMelon
Custom Fields (Application)
Crelate
Custom Fields on Application
1:1LogicMelon custom fields on Application records are mapped to Crelate Application custom fields. Like Job custom fields, destination fields are pre-created during the schema phase with equivalent types. Multi-select picklists in LogicMelon map to Crelate multi-select picklists or text fields depending on Crelate's field-type availability at the customer's plan tier.
LogicMelon
Attachments (non-CV)
Crelate
File Attachments on Job / Application
1:1File attachments beyond CVs—supporting documents attached to Jobs or Applications in LogicMelon—are extracted from the file store and reattached to the corresponding Crelate record. We identify attachment types during discovery and route them to the correct parent record (Job or Application) based on the original attachment context in LogicMelon.

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.
LogicMelon gotchas
EMEA vs USA API instance split affects endpoint routing
API authentication ties credentials to organisation structures
Job board target lists are stored per job, not globally
CV documents are binary attachments without a standard parseable schema
Crelate gotchas
120 req/min API rate limit throttles bulk migrations
20 custom field per-entity cap forces data model decisions
15,000-record export ceiling on single operations
Sequences and automation workflows do not migrate
API key is a querystring parameter, not a header
Pair-specific challenges
Migration approach
Discovery and API instance verification
We audit the source LogicMelon account to confirm the correct API instance (EMEA/APAC vs US), extract object counts (Jobs, Applications, Candidates, custom field schemas, attachment volumes), and identify the recruiter user assignments and organisation hierarchy. We verify the API credentials are scoped to the correct organisational unit with read permissions on all records to be migrated. The discovery output is a written scope document with record counts, schema inventory, and plan-tier recommendation for Crelate.
Schema pre-creation in Crelate
Before any data import, we pre-create the destination schema in Crelate. This includes creating Job custom fields (matching LogicMelon's field names and types), Application custom fields, the Application Status picklist values mapped from LogicMelon's pipeline stages, and tags for the job board target list preservation. If the customer's custom field count exceeds the Crelate plan limit, we identify overflow fields for the admin to prioritize during scoping.
Test migration into Crelate sandbox
We run a full test migration using production-like data volume into a Crelate environment (or a subset if no sandbox is available). The customer reconciles record counts, spot-checks candidate records against the LogicMelon source, verifies the CV attachment pass, and validates the Application split (confirming each LogicMelon Application produced a Crelate Contact and a linked Application). Any mapping corrections and schema adjustments happen here before production migration begins.
Candidate and CV import pass
We run the Contact import pass first, extracting LogicMelon Candidate records and structured profile fields and inserting them into Crelate as Contacts. CV file attachments are extracted and attached to the corresponding Crelate Contact record in the same pass. The original LogicMelon Candidate and Application IDs are stored as custom fields on each Crelate Contact for reconciliation.
Job import and Application split pass
LogicMelon Job records are imported into Crelate with the original board target list preserved as a tag on each Job. We then run the Application split pass, using the stored LogicMelon Application ID as the reference key to link each Crelate Application to the correct Crelate Contact and Crelate Job. Screening notes and scores migrate to the Application record as custom fields. Recruiter assignments are resolved by email against Crelate Users, with unresolved owners queued for admin provisioning.
Cutover, delta sync, and inventory handoff
We freeze writes to LogicMelon during the cutover window, run a final delta migration of any records modified since the initial extraction, then mark Crelate as the system of record. We deliver a written inventory of LogicMelon-specific objects that do not migrate: job board posting templates (replaced by Crelate's native distribution), LogicMelon Workflow Notes if any, and a recommendation on rebuilding multi-board posting in Crelate using the native LogicMelon integration. We support a one-week post-cutover window for reconciliation issues and do not include post-migration workflow rebuild or admin training in the standard scope.
