Overview
Moving from LogicMelon to Recruit CRM is a platform consolidation for staffing agencies that want a unified ATS plus CRM without the multi-posting aggregation layer. LogicMelon operates as a job distribution aggregator that pushes adverts outward to third-party boards and consolidates responses back into its pipeline; Recruit CRM is a native ATS plus CRM where job distribution happens through integrated XML feeds rather than a built-in multi-board layer. We extract Jobs, their associated Applications, Candidate profiles, and CV file attachments from LogicMelon and reconstruct them as native Recruit CRM Jobs, Candidates, and Applications. The job board target list stored per job in LogicMelon is preserved as a tag field in Recruit CRM rather than replicated as a posting action, because Recruit CRM's multi-board distribution uses a different XML feed and board-association model. Multi-posting workflow rebuilds fall outside migration scope; we deliver a written inventory of the original board distribution list for the customer's admin to reconfigure using Recruit CRM's built-in distribution tools.

Object mapping
Each row shows how a LogicMelon 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.
LogicMelon
Job
Recruit CRM & ATS
Job
1:1LogicMelon Job records map to Recruit CRM Job records. The job advert content (title, description, requirements, location, salary) migrates directly to Recruit CRM's Job fields. The original LogicMelon job reference ID is preserved in a custom field for audit and cross-system reconciliation. The per-job board target list from LogicMelon is not replicated as a multi-posting action in Recruit CRM (Recruit CRM uses XML feed distribution configured at the account level), but the list of originally targeted boards is saved as a tag field on the Job record so teams can see the original posting distribution. We extract the board list during the discovery phase and build it as a comma-separated tag string in Recruit CRM during import.
LogicMelon
Candidate
Recruit CRM & ATS
Candidate
1:1LogicMelon Candidate profiles map to Recruit CRM Candidates. Structured fields (name, email, phone, location, skills, work history) migrate directly. Any CV document stored as a binary attachment in LogicMelon is extracted as a PDF or DOCX file and attached to the Recruit CRM Candidate record via the Recruit CRM Files API (POST /v1/files) with the attachment linked to the candidate_id. The original CV filename is preserved. Candidate status history from LogicMelon's pipeline stages migrates as a custom text field or as a note entry with the stage name and timestamp, depending on the customer's Recruit CRM plan configuration.
LogicMelon
Application
Recruit CRM & ATS
Application (linked to Candidate and Job)
1:1LogicMelon Application records — which represent a Candidate's response to a specific Job — map to Recruit CRM Application records. The mapping resolves the parent Candidate (by email or candidate_id) and parent Job (by original LogicMelon job reference) at migration time using lookup tables built during the discovery phase. Application status from LogicMelon (e.g. Applied, Screened, Interviewed, Offered) migrates to the Recruit CRM application stage, and any screening score fields are mapped to custom fields on the Application record.
LogicMelon
CV / Resume (file attachment)
Recruit CRM & ATS
File (attached to Candidate)
1:1LogicMelon CV documents are binary attachments linked to Candidate records. We extract the raw file (PDF or Word format) from LogicMelon's file store and upload it to Recruit CRM using the Files endpoint (POST /v1/files with candidate_id in the association). If multiple CVs are attached to a single LogicMelon Candidate (e.g. different versions or formats), all versions are uploaded with descriptive filenames (original_filename_v1.pdf, original_filename_v2.pdf) to preserve the complete record. The migration of CVs adds meaningful overhead because each file requires a separate API call to Recruit CRM, which is factored into the timeline estimate for large-volume migrations.
LogicMelon
Screening Notes
Recruit CRM & ATS
Comment or Custom Field on Application
1:1Recruiter notes and screening scores attached to LogicMelon Applications are extracted as structured text and mapped to Recruit CRM Notes (via POST /v1/notes) linked to the Application record, or to custom fields on the Application if the screening data follows a consistent scoring format. During discovery, we identify whether the customer's LogicMelon instance uses free-text notes, structured rating scales, or a combination, and configure the mapping accordingly before migration begins.
LogicMelon
Pipeline Stages
Recruit CRM & ATS
Application Stage (configuration)
lossyLogicMelon pipeline stages are configurable per customer (Applied, Screened, Interviewed, Offered, Hired, Rejected, etc.). We extract the customer's active stage names during discovery and map them to equivalent Recruit CRM application stages. If the destination Recruit CRM instance uses different stage names, we configure the stage mapping in a custom field first so that status history is preserved accurately rather than defaulting to an arbitrary stage that loses meaning.
LogicMelon
Job Board Targets (per-job association)
Recruit CRM & ATS
Tag (on Job record)
1:1LogicMelon stores the list of job boards targeted per job advert as a board-association object rather than a global template. During migration, we extract each job's board list and create Recruit CRM tags for each board name (Indeed, LinkedIn, Reed, etc.). The tags are associated with the Job record. This preserves the original distribution footprint for audit and reference, but it does not recreate the multi-posting action itself — Recruit CRM distributes jobs through XML feed configuration in its job board settings, which is a separate configuration step the customer's admin handles post-migration.
LogicMelon
Organisation / Sub-Unit
Recruit CRM & ATS
Company or Team (depending on structure)
lossyLogicMelon's multi-tenant hierarchy (agency-level vs. client-level or sub-unit structures) requires a structural decision in Recruit CRM. If the agency operates multiple client desks or brands, we map the LogicMelon sub-unit hierarchy to Recruit CRM Companies (for client-facing structures) or to Recruit CRM Teams (if the destination instance has Team features enabled on the plan). We make this call during discovery based on the customer's intended Recruit CRM plan configuration.
LogicMelon
User (Recruiter)
Recruit CRM & ATS
User
1:1LogicMelon users tied to the organisation via API credentials are mapped to Recruit CRM users by email match. We extract the hubspot_owner_id or recruiter assignment from LogicMelon Jobs and Applications and match against the Recruit CRM user table during import. Any LogicMelon user without a matching Recruit CRM user is flagged in the reconciliation report for the customer to provision before record assignment migrates. Active vs. inactive status on the Recruit CRM side is determined by whether the original recruiter is still engaged with the team.
LogicMelon
Custom Fields (Job and Application)
Recruit CRM & ATS
Custom Fields
lossyLogicMelon allows custom fields on Jobs and Applications. During discovery, we identify all active custom fields and their data types (text, number, date, picklist, checkbox). We pre-create equivalent custom fields in Recruit CRM before migration begins using the Recruit CRM custom fields API (POST /v1/custom-fields). Type mismatches (e.g. a LogicMelon free-text custom field that should map to a Recruit CRM picklist) are resolved by the customer's admin during the scoping phase to avoid silent data truncation.

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 scoping
We audit the source LogicMelon account across region (EMEA/APAC or US to determine the correct API instance), active Jobs, Applications, Candidates, custom fields, pipeline stage configurations, and file attachment volumes. We verify the customer's Recruit CRM plan tier to confirm API access availability. The discovery output is a written migration scope document that includes the LogicMelon API instance routing decision, a record count estimate for Jobs, Candidates, Applications, and CV attachments, and the custom field mapping plan.
Recruit CRM environment setup
We request Recruit CRM API credentials (Business Plan required) and verify the destination environment. We pre-create all custom fields identified in discovery that do not already exist in the Recruit CRM instance, using the custom fields API to match LogicMelon field types (text, picklist, number, date). We configure any non-standard application stages to match the LogicMelon pipeline stages. We verify that the rate limit for the destination account is understood (60 rpm or 10 per license) so that the extraction pipeline is tuned before data movement begins.
LogicMelon data extraction in dependency order
We extract LogicMelon data in a strict dependency order: first Organisations and Users (needed for ownership resolution), then Jobs (the parent record for applications), then Candidates (the parent record for applications and the record linked to CV files), then Applications (linking Candidates to Jobs), then file attachments (CVs and supporting documents). Each extraction phase emits a row-count reconciliation report. We use the correct LogicMelon API base URL (api.logicmelon.co.uk or api.usa.logicmelon.com) determined during discovery, and we handle the organisation-scoped authentication by including the correct username parameter on each API call.
Job board metadata extraction and tag preparation
During the Jobs extraction, we capture the per-job board target list stored in LogicMelon. We transform this list into a comma-separated string suitable for Recruit CRM's tag format. We build a tag dictionary during this phase that maps each unique board name from LogicMelon to a Recruit CRM tag. This metadata is preserved as tags on the Job record in Recruit CRM during the import phase. We explicitly document in the migration report that this is metadata only and does not recreate the multi-posting action, so the customer's admin can configure Recruit CRM's XML feed distribution separately.
CV file extraction and Recruit CRM attachment upload
We extract CV binary files from LogicMelon's file store, grouping them by candidate_id. For each CV file, we upload to Recruit CRM using the Files API (POST /v1/files) with the candidate_id association and preserve the original filename. Rate limit headers from Recruit CRM are respected on every upload; we track remaining quota using the X-RateLimit-Remaining header and back off when the limit is approached. For accounts with more than 5,000 CV attachments, we parallelise the non-file extraction work and run file uploads in a dedicated rate-limited queue to avoid blocking the main record migration.
Recruit CRM import in dependency order and reconciliation
We load data into Recruit CRM in dependency order: Companies (for org structures), Users (for ownership resolution), Jobs (with board tags), Candidates (with CV file associations), Applications (resolving parent Candidate and Job lookups), then custom field data. Each phase includes a reconciliation check comparing the record count loaded in Recruit CRM against the count extracted from LogicMelon. We flag any discrepancies for investigation before proceeding to the next phase. Once all phases pass reconciliation, we deliver the migration handoff report including the original board target list, any unmapped custom fields, and the Workflow and automation rebuild inventory.
