Overview

What this migration involves

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.

Why teams make this switch

Two sides of the same decision

Leaving

What's pushing teams away

  • Editing an existing live job post can take a long time to propagate changes, particularly when the advertisement needs reformatting after the initial posting went live.
  • Posting latency varies by job board — some boards update within minutes while others take significantly longer, creating inconsistent candidate response windows.
  • Users report that third-party job board search results can behave unexpectedly with new contracts, introducing friction when sourcing across newly activated boards.
  • The interface becomes laggy under heavy multi-board posting loads, particularly when managing large volumes of concurrent job adverts and candidate records.

What's pulling them in

  • Affordable per-seat pricing with transparent tiers makes Crelate accessible for small-to-mid staffing firms evaluating ATS platforms for the first time.
  • Fast implementation reported by customers—some describe getting live in a matter of minutes with support team assistance.
  • Unified ATS + CRM in a single product eliminates the need to buy and synchronize separate recruiting and sales tools.
  • Flexible custom fields across Contacts, Companies, and Opportunities allow recruiting teams to capture firm-specific data without developer involvement.
  • Positive reviews highlight the product's intuitive interface and functional breadth for teams that need recruiting workflows without enterprise overhead.

Object mapping

How LogicMelon objects map to Crelate

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

maps to

Crelate

Job

1:1
Fully supported

LogicMelon 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

maps to

Crelate

Candidate (Contact)

1:many
Fully supported

LogicMelon 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

maps to

Crelate

Application

1:many
Fully supported

The 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

maps to

Crelate

Contact with Resume attachment

1:1
Fully supported

LogicMelon 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

maps to

Crelate

Notes / Activity Form fields

1:1
Mapping required

Recruiter 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

maps to

Crelate

Application Status values

lossy
Mapping required

LogicMelon'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

maps to

Crelate

Tag on Job record

1:1
Fully supported

LogicMelon 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)

maps to

Crelate

User

1:1
Fully supported

LogicMelon 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

maps to

Crelate

Organisation or Company

1:1
Fully supported

LogicMelon'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)

maps to

Crelate

Custom Fields on Job

1:1
Fully supported

LogicMelon 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)

maps to

Crelate

Custom Fields on Application

1:1
Fully supported

LogicMelon 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)

maps to

Crelate

File Attachments on Job / Application

1:1
Fully supported

File 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.

Pair-specific challenges

  • LogicMelon API instance routing by region

    LogicMelon operates two distinct API instances: api.logicmelon.co.uk for EMEA and APAC customers, and api.usa.logicmelon.com for US customers. The documentation pages and endpoint structures differ between instances. We determine the correct instance during scoping by checking the customer's account region, then configure our connector to the matching base URL. If the wrong instance is targeted, authentication succeeds but all object queries return empty results. This is the first gating item in any LogicMelon migration and must be resolved before any extraction begins.

  • API credentials tied to organisation and username context

    LogicMelon's API keys are tied to the organisation hierarchy and the username value in each request provides the access context. Migration credentials must be scoped to the correct organisational unit containing the data being migrated. We verify the username used in API calls matches a user with appropriate read permissions before beginning extraction. If the wrong organisational unit is scoped, records from other units may be inaccessible or the extraction returns partial data.

  • Application split requires two-pass import with referential integrity

    LogicMelon stores candidate data and application metadata in a unified Application record. Crelate separates Candidates (Contact) from Applications. We split each LogicMelon Application into two Crelate records in the correct dependency order: Contact first (to obtain the Crelate record ID), then Application (using the resolved Contact ID as a foreign key). The original LogicMelon Application ID is stored as a custom field on both records to enable reconciliation. Skipping the ordered import causes referential integrity failures on the Application-to-Contact link.

  • Crelate plan tier gates advanced custom fields and automation

    Crelate's Business plan includes 10 Advanced Custom Fields per module, 20 Custom Activities, and 20 Activity Templates. Business Plus and Enterprise tiers raise these limits. We audit the customer's LogicMelon custom field count during discovery and flag any mapping that exceeds the target Crelate plan's limits. If the customer's LogicMelon instance uses more custom fields than the destination plan supports, we identify overflow fields for admin decision on priority.

  • CV files migrate as attachments, not parsed resume data

    LogicMelon stores CVs as binary file attachments linked to Candidate profiles. We extract the raw file (PDF or Word) and attach it to the Crelate Contact record. LogicMelon's structured profile fields migrate directly to Crelate Contact fields. The CV file serves as a backup-of-record where structured fields are incomplete, but Crelate's built-in resume parser will re-parse the attached file into structured fields post-migration, potentially overwriting manually entered data if the customer runs the parser after import.

Migration approach

Six steps for a successful LogicMelon to Crelate data migration

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

Most LogicMelon to Crelate migrations land between two and four weeks for accounts with under 10,000 records (Jobs, Applications, Candidates) and a clean custom field schema. Migrations with high CV attachment volumes (over 5,000 files), a large number of custom fields, complex organisation hierarchies, or job boards with extensive board-target lists move to six to ten weeks because of the file extraction pass, the Application split transform, and the schema reconciliation scope.
