Overview
Moving from Sloneek to BambooHR is a platform migration that requires export-based extraction from Sloneek due to its undocumented API, followed by structured import into BambooHR's REST API. Sloneek organizes employee data across core HR, ATS, attendance, performance, and payroll modules, each with its own field schema that varies by plan tier; BambooHR consolidates these into a unified HRIS with employee records, onboarding, time-off, and benefits as core objects. We handle the full lifecycle data transfer including custom field discovery and mapping, GDPR consent flag preservation, and the Attendance 2.0 schema split that coexists in live Sloneek tenants. Workflows, AI automations, and approval chains do not migrate as code; we deliver a written inventory for your admin to rebuild in BambooHR's template-driven system. BambooHR's well-documented API and custom field builder give us a clear import path once the source data is extracted and validated.
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.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Sloneek object lands in BambooHR, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Sloneek
Employees
BambooHR
Employee
1:1Sloneek employee profiles (name, contact, job title, department, location, employment dates) map directly to BambooHR Employee records. Custom fields on Sloneek employee profiles are discovered during scoping, typed using BambooHR's Custom Field Builder (text, number, date, dropdown, checkbox, or employee-dependent types), and imported as BambooHR custom fields. We preserve the employee's status (active, inactive, terminated) and any GDPR consent flags as BambooHR custom fields for compliance continuity.
Sloneek
Organizational Structure
BambooHR
Location and Department
1:1Sloneek departments, cost centers, and org chart hierarchies export as structured CSV with parent-child relationships. We reconstruct these in BambooHR as Locations (physical work sites) and Departments (cost-center groupings), and restore reporting lines by setting each employee's department and supervisor field against the resolved BambooHR employee records. Org chart order is preserved in a custom ordering field for post-migration reconstruction if needed.
Sloneek
Documents
BambooHR
Employee Files
1:1Sloneek trust-box documents migrate as file attachments on the corresponding BambooHR employee record. We flag every non-PDF attachment in the source data (Sloneek accepts PDF only) and alert the customer during scoping that these files require pre-conversion before import; BambooHR accepts multiple formats. E-signature metadata on documents migrates as a note field for the customer's admin to act on in BambooHR's e-sign workflow.
Sloneek
Absences
BambooHR
Time Off
1:1Sloneek absence requests, accrual balances, leave types, and approval statuses map to BambooHR Time Off. We map Sloneek leave categories (vacation, sick, parental, unpaid) to BambooHR's Time Off types, and carry the accrual balance as of the migration date into BambooHR's starting balance field. Approval history and notes migrate as BambooHR Time Off request comments for audit continuity.
Sloneek
Attendance Records (dual schema)
BambooHR
Time Tracking
1:1Sloneek's ongoing Attendance 2.0 rollout means a single tenant may contain records in both the old and new attendance schema with different field names and structures. We detect which schema each record uses at export time, normalize both schemas into a unified format, and import the combined history into BambooHR Time Tracking. The migration date determines which records qualify for accrual carry-forward versus history-only import. Records are never dropped during this transition window.
Sloneek
ATS Candidates
BambooHR
Job Applicants
1:1Sloneek ATS candidate records (including resumes, notes, GDPR consent flags, and recruitment pipeline stage) map to BambooHR Job Applicants. Candidate sourcing channel, application date, and stage history migrate as BambooHR application status and a custom stage-history field. GDPR consent timestamps and opt-out flags carry forward as BambooHR custom fields on the applicant record. The customer may need to reconfigure BambooHR's hiring pipeline stages to match Sloneek's stage names; we document the mapping in the migration handoff.
Sloneek
Performance Reviews
BambooHR
Performance Reviews
1:1Completed Sloneek performance review cycles (360-degree feedback, goals, ratings) migrate as BambooHR Performance Review records. In-progress and draft reviews are migrated as historical data with a status flag but are not set as active BambooHR review cycles; the customer's HR admin activates cycles post-migration. Rating scales are mapped to BambooHR's rating fields, with any non-matching scale values preserved in a custom notes field.
Sloneek
Compensation History
BambooHR
Paychange
1:1Sloneek salary, bonus, and deduction history migrate as BambooHR Paychange records where available on the customer's plan tier. Paychange entries carry effective date, pay amount, and change reason. Compensation records that Sloneek stores in its payroll module may require separate export confirmation depending on the customer's Sloneek plan tier; we verify payroll module access during discovery and include compensation in scope only when data is confirmed present.
Sloneek
Custom Fields
BambooHR
Custom Fields
lossySloneek custom fields on employee profiles and select modules are discovered during scoping via export analysis. Each custom field's type (text, numeric, dropdown, date, boolean) is inferred from the data values and mapped to an equivalent BambooHR custom field type. We use BambooHR's Custom Field Builder (accessible to admins without a support request per their 2025 product update) to provision destination fields before record import. Fields without a clear BambooHR equivalent are documented as unmapped in the handoff with an explanation of why no target field exists.
Sloneek
Assets
BambooHR
Assets
1:1Company assets assigned to employees in Sloneek (equipment, licenses, access credentials) migrate as BambooHR Asset records linked to the corresponding employee. Asset ID, name, type, assigned date, and return status transfer as BambooHR asset fields. Any asset with a pending assignment at migration time is flagged in the reconciliation report for the customer's admin to complete post-migration.

Migration approach
Discovery and export access request
We audit the customer's Sloneek tenant for active modules (core HR, ATS, attendance, performance, payroll), custom field schema, document attachment volume, and plan tier. Because Sloneek has no public API, we submit a support request to obtain CSV or bulk export access and confirm which modules are gated by the current plan tier. We also verify the BambooHR destination plan tier and identify any features (performance reviews, compensation management) that require an upgrade before their data objects are in scope. Discovery output is a written migration scope with record counts per object and a list of any missing source data due to plan tier gaps.
Data extraction and schema mapping
We extract employee records, organizational structure, absence balances, attendance history, ATS candidates, performance reviews, and compensation data from Sloneek using the confirmed export mechanism. Custom fields are discovered from the export schema and mapped to BambooHR field types. Where Sloneek's Attendance 2.0 and legacy attendance schemas coexist, we separate records by schema version and normalize field names to a unified intermediate format before any transformation. Non-PDF document attachments are flagged with file type, original filename, and employee association for the customer's pre-conversion task list.
Destination schema provisioning
We provision the BambooHR destination schema using the API: Departments, Locations, custom fields (via the Custom Field Builder), and Time Off types are created before any record import begins. BambooHR's Custom Field Builder is accessible to admins directly, so custom fields are provisioned by the customer or by us with delegated admin access. Time Off type names are matched to Sloneek leave categories, and accrual carry-forward amounts are set to the balance as of the migration date.
Sandbox validation and reconciliation
We run a full migration into the customer's BambooHR sandbox environment using production-like data volume. The customer's HR lead spot-checks 25-50 employee records against the Sloneek source, verifies absence balances, confirms ATS candidate pipeline mapping, and reviews document attachment availability. Any field mapping corrections, missing data gaps, or schema adjustments are resolved in sandbox before production migration begins. No data is modified in the production BambooHR environment until sandbox sign-off is received.
Production migration in dependency order
We run production migration in dependency order: Locations and Departments first (as reference data), then Employees with custom fields and reporting lines resolved, Time Off balances and history, ATS Candidates with GDPR flags and pipeline stages, Performance Review records, Compensation Paychange entries, and Attendance history (both schemas normalized). Document attachments upload in parallel with employee records, with non-PDF files held until pre-conversion is confirmed complete. Each phase emits a row-count reconciliation report before the next phase begins.
Cutover, validation, and handoff
We freeze writes in Sloneek during cutover and run a final delta migration of any records modified during the migration window. BambooHR becomes the system of record once the delta is confirmed. We deliver a written inventory of Sloneek workflows, approval chains, and Sloneek Intelligence AI automations requiring rebuild in BambooHR (which uses a template-driven workflow model rather than a code-based automation builder). We support a one-week post-migration window to resolve any data reconciliation issues raised by the customer's HR team.
