Overview

What this migration involves

Sloneek is a Central European all-in-one HRIS where the ATS module sits alongside Core HR, payroll, attendance, and performance. Crelate is a US-based recruiting ATS and CRM purpose-built for staffing and recruiting agencies with a Living Platform powered by AI agents for candidate discovery and database enrichment. The migration is not a record copy — it is a schema translation from an HRIS data model (Employees, Documents, Absences, Org Structure) to a recruiting data model (Contacts, Companies, Opportunities, Activity Forms). We resolve the Candidate-from-Employee object split during scoping, map Sloneek's time-off balances to Crelate Activity Forms with custom field carry-through, and flag the dual attendance schema (Attendance 2.0 transition in progress) before any data moves. Approval chains, GDPR consent management, and custom field configurations do not migrate as code; we deliver a written inventory for your admin to rebuild in Crelate's Settings.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

AI proposes the map; you confirm before any record moves.

Relationships preserved

Sloneek

What's pushing teams away

  • Complex feature depth creates a steep learning curve for administrators new to HRIS systems, particularly around workflow configuration and module interconnections.
  • Document management restricted to PDF format only, frustrating teams that need to store Word documents, spreadsheets, or image-based records as employee files.
  • API is not publicly documented, blocking automation and integration use cases that require programmatic access to employee records or attendance data.
  • Some modules (ATS, advanced performance, payroll) require higher plan tiers, creating feature gaps for customers who expected full coverage at the base price.
  • Limited third-party integrations outside of Slack and JIRA, making it difficult to connect Sloneek data into broader analytics or finance tooling.

Object mapping

How Sloneek objects map to Crelate

Each row shows how a Sloneek 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.

Sloneek

ATS Candidate

maps to

Crelate

Contact

1:1
Fully supported

Sloneek ATS Candidates map to Crelate Contact records. Candidate name, email, phone, resume, GDPR consent flags, and application stage migrate directly. The Sloneek candidate record's pipeline stages (Applied, Screening, Interview, Offer, Hired) map to Crelate's Job Applicant Status on the submission record. GDPR consent storage from Sloneek's ATS module migrates to the Contact's custom consent field, preserving the original consent timestamp and scope. Candidate notes migrate as Crelate Note records attached to the Contact.

Sloneek

ATS Candidate

maps to

Crelate

Company (from candidate employer data)

1:many
Fully supported

When a Sloneek ATS Candidate includes current employer or organization data, we split that into a separate Crelate Company record linked to the Contact via the Company lookup on Contact. The Sloneek candidate's application history against specific job positions migrates as Crelate Opportunity records (representing placements or submissions) with a Job reference. This split is important because Crelate separates person records (Contacts) from organization records (Companies) with a relational model that Sloneek's flat candidate profile does not enforce.

Sloneek

Employee

maps to

Crelate

Contact (custom HR extension)

1:1
Fully supported

Sloneek Employee records (name, contact info, job title, department, location, hire date, termination date) map to Crelate Contact records with a custom Sloneek migration field (sloneek_employee_id__c) preserving the source reference. Employee reporting lines and department assignments map to Crelate Company records representing the employer organization. Active employee status is preserved; terminated employees are migrated as inactive Contacts with sloneek_status__c = Terminated. The Sloneek organizational hierarchy (departments, cost centers, reporting lines) maps to Crelate Company and hierarchy where the customer uses Crelate for internal employee tracking alongside recruiting.

Sloneek

Document (Trust Box)

maps to

Crelate

ContentDocument (via File upload)

1:1
Fully supported

Sloneek's trust-box documents (contracts, certifications, IDs) migrate as Crelate file attachments linked to the Contact record. We flag every non-PDF attachment during scoping and alert the customer that Sloneek accepts PDF files only for upload — any scanned documents, Word files, or images in the source data must be pre-converted or uploaded manually post-migration. Crelate does not have a native trust-box equivalent; document storage relies on standard Salesforce ContentDocument which lacks built-in e-signature lifecycle tracking. If e-signature tracking is required, the customer should configure DocuSign or similar integration separately.

Sloneek

Absence

maps to

Crelate

Activity Form (custom absence fields)

lossy
Fully supported

Sloneek absence records (time-off type, balance, accrual, approval status) migrate to Crelate Activity Forms with custom fields capturing the absence type (Vacation, Sick, Personal), current balance, accrual rate, and original approval date. Sloneek leave types are enumerated during discovery and mapped to Crelate Activity Form categories. Crelate does not have a native time-off accrual engine; we carry the balance snapshot as of the migration date as a read-only custom field on the Activity Form record. Accrual resets post-migration are managed by the customer's HR admin in Crelate's absence management or a connected payroll system.

Sloneek

Attendance Record (dual schema)

maps to

Crelate

Activity Form (time entry)

1:1
Fully supported

Sloneek is actively transitioning from the old attendance module to Attendance 2.0, and both schemas coexist in live tenants. We detect which schema applies to each record at export time by inspecting the field structure (old schema uses legacy field names; Attendance 2.0 uses updated field names per Sloneek's December 2025 release notes). Both schemas map to Crelate Activity Forms capturing clock-in, clock-out, total hours, and absence flag. The schema detection step adds a pre-migration data audit of 1-3 business days before the export begins. No attendance history is dropped during the transition window.

Sloneek

Job Position

maps to

Crelate

Job + Opportunity

1:many
Fully supported

Sloneek ATS job positions map to Crelate Job records (position title, department, location, job description) plus an Opportunity record representing the active requisition or headcount opening. Sloneek's position status (Open, On Hold, Filled, Closed) maps to Crelate's Job status. The Opportunity in Crelate tracks the hiring pipeline and is linked to the Job. This split reflects Crelate's recruiting workflow where Jobs represent the position definition and Opportunities represent the active sourcing effort against that position.

Sloneek

Compensation History

maps to

Crelate

Custom Fields on Contact

1:1
Mapping required

Sloneek payroll and compensation records (salary, bonuses, deductions, payroll history) migrate to custom fields on the Crelate Contact record (crelate_salary__c, crelate_bonus__c, crelate_last_raise_date__c). Access depends on the customer's Sloneek plan tier — payroll module access requires the appropriate plan. We verify module availability during discovery and exclude non-existent compensation records from the migration contract upfront. Crelate does not have a native payroll module; compensation data is stored as read-only custom fields for reference by the recruiting team.

Sloneek

Organizational Structure

maps to

Crelate

Company (hierarchical)

1:1
Fully supported

Sloneek departments, cost centers, and org chart hierarchies map to Crelate Company records with parent-company hierarchy configured where the customer's org structure has multi-level reporting. Employee reporting lines from Sloneek migrate as Contact-to-Company relationships. Department cost center codes are preserved in custom fields on the Company record. Org chart visualization is not native to Crelate; the customer may configure a third-party org chart tool or use Crelate's reporting to reconstruct the hierarchy.

Sloneek

Workflows and Approvals

maps to

Crelate

Configuration documentation (rebuild required)

lossy
Mapping required

Sloneek approval chains for time-off, expenses, and document signing do not migrate as code into Crelate because the workflow models are structurally different. We document every Sloneek approval chain during scoping (trigger, conditions, approvers, escalation path) and deliver a written inventory recommending equivalent Crelate configurations using Crelate's Workflow settings, Activity Forms with approval routing, and any third-party approval tools the customer adopts. The customer's admin rebuilds approval rules in Crelate's Settings area post-migration.

Sloneek

Custom Fields

maps to

Crelate

Custom Fields on Core Records

lossy
Mapping required

Sloneek custom fields on Employee profiles and ATS Candidate records migrate to custom fields on Crelate Contact (the primary recipient object). Crelate supports custom fields on Contact, Company, and Opportunity (the three core record types). We discover the full custom field schema during scoping, map field types to their Crelate equivalents (text, number, date, picklist, checkbox), and pre-create fields in Crelate's Settings | Core Records area before migration begins. Crelate limits Advanced Custom Fields to 10 on the Business plan; Enterprise unlocks higher limits.

Sloneek

Assets

maps to

Crelate

Custom Fields or Notes on Contact

1:1
Fully supported

Sloneek company assets assigned to employees (equipment, access cards, licenses) are exported as a mapping table (asset ID, asset type, assigned employee, assignment date). In Crelate, we attach this as a structured Note record on the Contact with asset details, or as custom text fields if the asset list is small and static. Crelate does not have a native asset tracking module; the mapping table is delivered as a CSV alongside the migration for the customer's admin to maintain in a separate asset management system.

Pair-specific challenges

  • Sloneek API is undocumented; extraction requires support coordination

    Sloneek does not publish API documentation or a public developer portal, which means we cannot make authenticated API calls to pull data programmatically. We rely on Sloneek's export utilities and manual data dumps for migration scoping. Before migration, we must confirm with the customer which data modules are active and request CSV or bulk export access through their support channel. This adds a pre-migration coordination step of 3-7 business days that is not present when migrating from platforms with documented APIs. Crelate, by contrast, has a fully documented REST API that we use for importing migrated data.

  • Attendance 2.0 dual-schema coexistence requires schema detection

    Sloneek is actively transitioning from the old attendance module to Attendance 2.0, and both run in parallel per the December 2025 release notes. A single Sloneek tenant may have attendance records split across two schemas with different field names and structures. We detect which schema applies to each record at export time before migration begins. Without schema detection, attendance records from the old schema are dropped or mis-mapped during import into Crelate. This step adds 1-3 business days to the pre-migration data audit.

  • PDF-only document restriction may reduce file carry-through

    Sloneek's trust-box document module accepts only PDF files for employee records. Scanned documents, Word files, spreadsheets, and images must be converted before they can be uploaded to Sloneek. During migration into Crelate, we flag every non-PDF attachment in the source data and alert the customer that these will require pre-conversion or manual upload post-migration. Crelate accepts any file type as a ContentDocument attachment, but Sloneek's restriction may have caused the customer to discard or not store non-PDF files at all, reducing the document carry-through volume.

  • Crelate requires specific fields; missing values return HTTP 500

    Crelate's API enforces required field constraints. When saving via API, the following attributes are required or the request returns HTTP 500: Company requires Name, Job requires Name, Note requires Body, Task requires Body. We pre-validate every record before API insert and populate required fields with a placeholder value (e.g., Unknown) where the source Sloneek field is empty. Lookup fields require the _Id, _FirstName, and _LastName triplet per Crelate's lookup resolution rules. Migrations that skip pre-validation encounter record rejection at import time, requiring retry batches.

  • ATS-versus-HRIS object model gap means no native absence accrual engine in Crelate

    Sloneek's HRIS roots include a native time-off accrual engine with balance tracking, accrual rules, and carryover logic. Crelate is an ATS and recruiting CRM with no native absence accrual engine. We carry absence balances as read-only custom fields on Activity Form records, but accrual resets, carryover calculations, and negative balance enforcement must be handled by the customer's HR admin post-migration or through a connected HR and payroll system. This is not a data migration gap but a post-migration configuration gap the customer should plan for.

Migration approach

Six steps for a successful Sloneek to Crelate data migration

  1. Discovery and module availability verification

    We audit the Sloneek tenant across active modules (Core HR, ATS, Attendance, Payroll, Performance), custom field schemas on Employee and Candidate objects, document volume and file type distribution, and organizational structure depth. We verify which Sloneek plan tier the customer is on because ATS, payroll, and advanced performance modules are gated behind higher tiers. We also identify whether the attendance data spans one or both schemas (old attendance and Attendance 2.0). The discovery output is a written migration scope, a module availability checklist, and a pre-migration CSV export request submitted through Sloneek's support channel.

  2. Crelate schema design and custom field provisioning

    We configure the Crelate destination tenant before any data moves. This includes provisioning custom fields on Contact, Company, and Opportunity (matching Sloneek's custom field schema), setting up Activity Forms for absence and time-entry capture, creating Job records from Sloneek job positions, and configuring the Sloneek migration tag field on all core records. Crelate's Advanced Custom Fields limit is 10 on the Business plan and higher on Business Plus and Enterprise; we verify the customer's plan tier before designing the custom field schema. Schema is validated in a Crelate test environment before production deployment.

  3. Test migration and schema validation

    We run a full test migration using production-like data volume into Crelate's staging or sandbox environment. The customer's HR and recruiting leads reconcile record counts (Contacts in, Companies in, Activity Forms in), spot-check 20-30 random records against the Sloneek source, verify GDPR consent flag placement, and validate that document file types are correctly handled. Any mapping corrections — field type mismatches, missing required fields, lookup resolution failures — are documented and corrected before the production migration begins. Approval chain inventory documentation is also delivered during this phase.

  4. Production migration in dependency order

    We run production migration in record-dependency order: Companies (from Sloneek organizational units and candidate employer data), Contacts (with CompanyId resolved from the Company phase), Jobs (from Sloneek job positions), Opportunities (linked to Jobs representing active requisitions), Activity Forms for absence balances and time entries (with schema detection applied for attendance records), Documents (as ContentDocument records attached to Contacts), and Custom Field carry-through (salary, consent flags, Sloneek source IDs). Each phase emits a row-count reconciliation report before the next phase begins. GDPR consent flags are validated against Sloneek's consent timestamps and scope.

  5. Cutover, delta sync, and approval-chain handoff

    We freeze Sloneek writes during the cutover window, run a final delta migration of any records modified during the migration window, then enable Crelate as the system of record. We deliver the approval-chain inventory document (covering time-off approval workflows, document signing chains, and any expense approval rules) to the customer's admin team with Crelate configuration recommendations. We support a 5-business-day hypercare window where we resolve any reconciliation issues raised by the customer's team. We do not rebuild Sloneek approval chains as Crelate workflows inside the migration scope; that is a separate configuration engagement or an internal admin task.

Most migrations land between three and five weeks for accounts under 500 ATS candidates and 1,000 employee records with no dual attendance schema present. Migrations with both old and new attendance schemas active, GDPR consent flag carry-through, custom field-heavy schemas, and time-entry history exceeding 10,000 records move to six to nine weeks because of the schema detection step, dual-export work, and custom field configuration. The pre-migration coordination with Sloneek support for CSV export access adds 3-7 business days before scoping begins.
