Overview
Moving from Martian Logic to BambooHR is a platform simplification and data extraction project. Martian Logic's position-centric model (where employees are linked to Positions that form the org chart) must be decomposed into BambooHR's flatter model of Employees linked to Departments, Job Information history, and a custom reporting tree. We extract the full Employee Database, parse the configuration-dependent JSON e-form payloads collected during onboarding, walk the Position hierarchy to rebuild the org chart in BambooHR's structure, and flatten Employment Change records into a per-employee history log. Integration Connector field mappings (which push data from Martian Logic into a payroll system) do not migrate; we deliver a written inventory of every active connector's source-to-destination field map so your admin can recreate the equivalent in BambooHR's native integrations or a middleware layer. BambooHR does not include a built-in ATS module at its base tier; if you are migrating candidate data, we can map it to BambooHR's optional Applicant Tracking module. Workflows, custom approval chains, and Smartform routing do not migrate as code.

Object mapping
Each row shows how a Martian Logic 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.
Martian Logic
Employee Database
BambooHR
Employee
1:1Martian Logic's Employee Database records map directly to BambooHR Employee. All personal details (name, date of birth, contact information, emergency contacts, address history) migrate as typed BambooHR fields. Martian Logic stores custom folders of additional data per employee (certifications, compliance documents, file attachments); we map each configured folder to a corresponding BambooHR custom field, creating the field in BambooHR first and then populating it. Historical employment status (active, on leave, terminated) migrates with the employee's termination date and reason preserved if applicable.
Martian Logic
Position
BambooHR
Department + Job Information
1:manyMartian Logic Positions are first-class objects linked to employees and forming the org chart hierarchy. BambooHR has no Position object; instead, we split each Position into a Department (derived from the Position's organisational unit) and a Job Information entry (title, FTE, location, manager). The Position's reporting chain becomes the BambooHR reporting structure under Employee > Manager. Positions archived or soft-deleted in Martian Logic require cleanup before migration to avoid orphaned nodes in the destination hierarchy.
Martian Logic
Position Hierarchy (Org Chart)
BambooHR
Employee Reporting Structure
lossyThe Martian Logic org chart is a derived view of Position-to-Position reporting chains, not a standalone object. We walk the Position hierarchy by resolving each position's reportsTo relationship, then reconstruct it in BambooHR by setting each employee's manager field to the employee who holds the parent Position. If the same Position is held by multiple employees (e.g., a role shared across a department), the primary incumbent maps to the manager field and additional holders are linked as department peers.
Martian Logic
Employment Change Records
BambooHR
Employee Job Information History
lossyMartian Logic Change of Staff Conditions records are effective-dated transactions with fields for change type, old value, new value, reason, and effective date. BambooHR does not store a transaction log of changes; instead, the current Job Information fields reflect the latest state. We flatten the change history into a per-employee custom field (a text block or a series of dated custom fields) that logs each change as a line item: date, change type, old value, new value. Customers who need full audit history retain it as a readable log rather than as queryable records.
Martian Logic
Onboarding Packs / E-forms
BambooHR
Employee Custom Fields
lossyOnboarding e-forms in Martian Logic store field values as configuration-dependent JSON payloads that vary by employer pack. There is no fixed schema across packs. We parse each employee's onboarding payload during extraction, build a per-pack field mapping, and create matching custom fields in BambooHR. Fields present in the source payload but with no BambooHR equivalent become free-text custom fields. BambooHR custom field creation is admin-accessible and does not require developer credentials, so the customer can add additional fields post-migration if needed.
Martian Logic
Compensation / Remuneration Library
BambooHR
Employee Pay Rate + Custom Fields
1:1Martian Logic stores compensation against or linked to Positions via the Role and Remuneration Library (base salary, allowances, pay frequency, effective-from date). We extract the most recent compensation record per employee and map base salary to BambooHR's payRate field. Allowances (car, phone, superannuation, bonus) migrate as a custom field group. BambooHR does not natively support effective-dated compensation history as a separate object; we store the latest compensation snapshot and log historical pay changes in the Employment Change history custom field.
Martian Logic
Candidates (ATS module)
BambooHR
Applicant (BambooHR ATS)
1:1Martian Logic ATS manages candidates through the full pipeline including requisition, application, interview score, and offer. If BambooHR Applicant Tracking is in use at the destination, we map Candidates to BambooHR Applicants with status history, application dates, and interview scores preserved as custom fields. If BambooHR ATS is not activated, candidates cannot be imported and we document the open requisitions and pipeline stages as a written inventory for the customer's admin to recreate manually or in a dedicated ATS tool. BambooHR ATS is a priced add-on; scoping must confirm whether it is active at the destination.
Martian Logic
Recruitment Requisitions
BambooHR
Job Openings (BambooHR ATS)
1:1Open and closed requisitions in Martian Logic (including requesting manager, approved headcount, status, and creation date) map to BambooHR Job Openings if the BambooHR ATS module is active. The requisition approval workflow is a Martian Logic configuration artefact that does not export; we document each open requisition's details and status so the customer can recreate the opening in BambooHR ATS without losing the hiring context.
Martian Logic
Integration Connectors
BambooHR
BambooHR Native Integrations / Middleware
lossyMartian Logic Integration Connectors push employee data to third-party payroll systems with custom field-to-field mappings. These connector configurations are not exportable from Martian Logic. We document every active connector's source field, destination field, and trigger condition during discovery. The equivalent integration must be rebuilt in BambooHR's native integrations or via a middleware tool (such as Zapier or Workato). BambooHR has a published integration catalogue; customers moving from Martian Logic's STP-integrated payroll tier should note that BambooHR Payroll is not available in Australia and will require a separate payroll product.
Martian Logic
ESS Access Levels
BambooHR
Employee Permissions + Custom Fields
lossyMartian Logic stores Employee Self-Service access levels and role permissions per employee or per role. BambooHR uses a role-based permission model (Employee, HR Admin, Manager, Super Admin) applied at the user level rather than per field. We export ESS access as a custom field on the employee record (e.g., can_approve_leave: Yes/No, can_view_payroll: Yes/No) so the information is preserved even though the permission enforcement model differs. Customers with role-based access configurations spanning many levels may need to rationalise the access model as part of the migration.

Migration approach
Discovery and data audit
We audit the source Martian Logic instance across all active modules: Employee Database (headcount, custom folders, field configurations), Position structure (active, archived, number of unique positions), Employment Change records (volume and change types in scope), onboarding pack configurations (number of distinct packs and e-form field lists), Integration Connector inventory (destination system, mapped fields, active/inactive status), and ATS pipeline data if candidates are in scope. We produce a written data inventory that defines exactly what will migrate, what will be documented for manual rebuild, and what cannot migrate due to platform incompatibility (primarily payroll integration configurations and approval workflow logic).
Schema design in BambooHR
We design the destination schema in BambooHR before any data moves. This includes provisioning all custom fields (mirroring Martian Logic custom folders, ESS access flags, and compensation allowances), configuring the department structure (mapped from Martian Logic Position organisational units), setting up the reporting tree, and confirming the BambooHR ATS activation status if candidate migration is in scope. BambooHR custom fields are created by the customer's admin with credentials we provide; we provide the field name, type, and options list for each. Schema design is validated against a test BambooHR tenant before production.
Position hierarchy walk and org chart reconstruction
We walk the Martian Logic Position hierarchy by querying each Position's reportsTo relationship, building a directed graph of the reporting chain. We identify orphaned nodes (archived positions with no valid parent), flag them for the customer's HR admin to resolve, and build a Position-to-Department mapping table. The primary holder of each Position maps to the manager field in BambooHR; co-holders map as department colleagues. The output is an employee-to-manager mapping file ready for bulk import into BambooHR's reporting structure.
Employee, compensation, and change history extraction
We extract the full Employee Database including all personal details, employment status, current Position assignment, and Role and Remuneration Library compensation snapshot. Each employee's change history (Martian Logic Employment Change records) is flattened into a dated log entry format for storage in a BambooHR custom field. Onboarding e-form payloads are parsed per pack, with each field mapped to the corresponding BambooHR custom field created during schema design. The extraction phase produces a set of CSV files (one per object type) and a JSON manifest of e-form field mappings per pack.
Sandbox migration and reconciliation
We run a full migration into a BambooHR sandbox environment using production-like data volume. The customer's HR lead reconciles record counts (employees imported vs employees expected, departments created vs positions mapped, custom fields populated vs e-form fields parsed), spot-checks 25-50 employee records against the Martian Logic source, and signs off the schema and mapping before production migration begins. Any mapping corrections—including missed e-form fields, incorrect manager assignments, and orphaned position handling—happen in the sandbox phase.
Production migration and cutover
We run production migration in dependency order: departments first, then employees (with manager references resolved from the hierarchy walk), then job information history (as custom fields), then compensation snapshots, then onboarding data. Each phase emits a row-count reconciliation report. We freeze writes in Martian Logic during the cutover window, run a final delta migration of any records modified during the window, then confirm BambooHR as the system of record. We deliver the Integration Connector inventory document and the workflow/approval rebuild checklist to the customer's admin team. A one-week post-migration hypercare window covers reconciliation issues raised within that period.
