Overview
Moving from CatalystOne to BambooHR is a scope reduction as much as a platform change. CatalystOne is a full-lifecycle HCM system built for Scandinavian enterprise customers with position-based data modelling, deep payroll integration on Azure, and a managed-service integration layer. BambooHR is a cloud HRIS designed for small and medium businesses with transparent per-seat pricing from $10 per employee per month, an intuitive admin interface, and a documented REST API. The migration centres on resolving CatalystOne's position-based data model (Positions carry title, department, and hierarchy) against BambooHR's simpler job-title and department fields, sequencing effective-dated records in chronological order, and exporting custom fields that live outside any published CatalystOne schema. Workflow configurations, payroll integration mappings, and managed Azure integration logic do not migrate because they are CatalystOne's intellectual property or live outside the API surface. We deliver those as written inventories for the customer's admin to rebuild or re-implement post-migration.

Object mapping
Each row shows how a CatalystOne 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.
CatalystOne
Person (Employee)
BambooHR
Employee
1:1CatalystOne Persons map to BambooHR Employees as the primary import. We extract core fields (firstName, lastName, preferredName, workEmail, mobilePhone, dateOfBirth, hireDate, terminationDate, employmentStatus) and map them to the corresponding BambooHR employee fields. Custom properties on the Person object vary by customer tenant — we run a pre-migration schema discovery pass against the specific customer's CatalystOne tenant via the developer portal to enumerate all active custom fields before designing the target schema. Custom fields that align to BambooHR standard fields map directly; those that do not are created as BambooHR custom fields or stored as document metadata.
CatalystOne
Position
BambooHR
Job Title + Department (flattened)
1:manyCatalystOne uses a position-based data model where a Position carries title, department, and hierarchy relationships. BambooHR does not have a separate Position object — job title is a field on the Employee record and department is a separate Department entity. We flatten the position-to-employee relationship by mapping Position.title to the employee's jobTitle field and resolving the Position's department reference to the corresponding BambooHR Department. Manager hierarchy migrates by setting each employee's supervisor in BambooHR to the manager's Employee record, resolved via name or employee ID matching.
CatalystOne
Competency
BambooHR
Custom Field or Document
lossyCatalystOne Competencies store skills, qualifications, and ratings in a structured many-to-many relationship with Persons. BambooHR does not have a native Competency object. We handle this by mapping competency records to BambooHR custom fields on the Employee record where ratings are structured (for example, language proficiency), or by exporting competency profiles as PDF documents attached to the relevant Employee record. The customer chooses the strategy during scoping based on how competency data is used post-migration.
CatalystOne
Succession Plan
BambooHR
Notes or Custom Field
lossySuccession data in CatalystOne is stored as a structured relationship between a Position and one or more candidate Persons with readiness ratings. BambooHR has no native succession planning object. We export the succession hierarchy and associate candidate readiness ratings as a structured note attached to the relevant Position's mapped employee record, or as custom fields if the succession relationship can be expressed as a finite set of candidate-employee references. We flag this as a gap in BambooHR's feature set and recommend a dedicated succession tool if succession planning is a core ongoing requirement.
CatalystOne
Performance Review
BambooHR
File Attachment or Custom Field
lossyCatalystOne Performance Reviews carry effective dates, reviewer assignments, ratings, and free-text responses against configurable review templates. Custom review templates mean field count and naming vary per customer. BambooHR's Performance module (Pro and Elite tiers) supports review cycles and goals but does not have a direct equivalent for historical completed reviews from a previous system. We export completed review records as structured PDFs attached to the relevant employee, preserving the rating data and review period. Active or pending reviews at migration time are migrated as BambooHR performance review records if the customer has the BambooHR Performance module enabled.
CatalystOne
Department (Org Structure)
BambooHR
Department
1:1CatalystOne maintains a department hierarchy with effective-dated historical structure changes. BambooHR has a flat Department list without native historical versioning. We import the current department hierarchy as BambooHR Departments, using the parentDepartment field to preserve the hierarchy chain. Historical org structure changes (effective-dated records showing past department assignments) are exported and delivered as a reconciliation document for the customer's records — they are not imported as live BambooHR records because BambooHR does not support effective-dated department history on the employee record.
CatalystOne
Document
BambooHR
File Attachment (Employee Documents)
1:1CatalystOne stores employee documents (contracts, certifications, policies, offer letters) as binary files with metadata (type, date, owner). We export file binaries alongside metadata and attach them to the corresponding BambooHR Employee record under the Documents section. Some document types (such as contracts with role-specific fields) require custom document type configuration in BambooHR, which we scope during discovery. Documents without an identifiable employee association are imported as company-level files.
CatalystOne
Identity and Access Records
BambooHR
Employee Fields + Notes
1:1CatalystOne links AD and SSO provisioning data and role or group assignments from HR master data. We export the current state of access records (role, group membership, system access flags) as fields on the BambooHR Employee record or as structured notes. Offboarding automation logic does not migrate because it lives in the identity provider layer, not in CatalystOne's API surface. The identity-to-HR mapping (which HR record corresponds to which AD account) is preserved via a cross-reference table we deliver alongside the data export.
CatalystOne
Payroll Integration Mappings
BambooHR
Configuration inventory (not migrated)
lossyCatalystOne syncs HR data to payroll providers (Visma, SAP, and Nordic payroll systems) via managed Azure-hosted integration logic that is CatalystOne's intellectual property and not handed over during migration. We export the field-to-field mappings and integration configuration as a written inventory document so the customer's payroll admin can re-implement the equivalent logic in BambooHR Payroll or their chosen destination payroll system. This is a manual rebuild scope, not an automated data migration.
CatalystOne
Custom Workflow Configurations
BambooHR
Configuration inventory (not migrated)
lossyCatalystOne approval workflows, automated triggers, and HR process rules are configured inside the application and are not exposed via the API. We do not export workflow logic as code. We document the active workflow configurations during discovery (workflow name, trigger, conditions, actions, affected records) as a written inventory for the customer's admin to rebuild in BambooHR using BambooHR's built-in approval routing and onboarding task sequence tools, or to document as a requirements brief for a BambooHR implementation partner.

Pair-specific challenges
Migration approach
Discovery and API access scoping
We request API key access to the customer's CatalystOne developer portal (developer.catalystone.com) and schedule a technical walkthrough with their CatalystOne technical contact. We audit the source tenant across all API-accessible objects, active custom fields, position hierarchy depth, document types and volumes, competency schema, performance review templates, and the active workflow inventory. We pair this with a BambooHR tenant assessment confirming which modules are licensed (Core, Pro, or Elite) and whether ATS, payroll, or benefits administration add-ons are in scope. The discovery output is a written migration scope document and a per-object export plan.
Schema design and position-model resolution
We design the BambooHR target schema based on the discovery output. This includes creating BambooHR custom fields for any CatalystOne custom properties that have no standard equivalent, configuring Departments with the parent-child hierarchy resolved from CatalystOne Positions, and defining the jobTitle field values by extracting titles from the position chain. We document the position-to-employee flattening logic (which Position record feeds which Person's job title and department) as a transform rule that executes before any employee records are written to BambooHR.
BambooHR API authentication and sandbox setup
We set up the BambooHR API integration by generating an API key from the customer's BambooHR admin console (Settings > API Keys), confirming the API key has read and write access to Employee, Department, Document, and any custom field objects in scope. We validate connectivity and field list retrieval using the BambooHR meta/fields endpoint to confirm the destination field names before beginning any import. All migration work runs first against a BambooHR sandbox or test tenant before touching production.
Sandbox migration and reconciliation
We run a full migration into the BambooHR sandbox using production-like data volumes. The customer's HR lead reconciles record counts against the CatalystOne source (employee count, department count, document count), spot-checks 20-30 employee records for field-level accuracy, and validates that manager relationships and department assignments are correctly resolved from the position chain. Any mapping corrections, custom field additions, or data quality issues (duplicate records, missing manager references, blank required fields) are resolved in the sandbox before production migration begins.
Production migration in dependency order
We run production migration in dependency order: Departments and locations first (no dependencies), followed by employees with manager references resolved to BambooHR Employee IDs, then documents attached to the relevant employee records, then competency profiles and performance review PDFs. Effective-dated records (historical department assignments, competency records with historical ratings) are sequenced in chronological order during export to preserve the record timeline. Each phase emits a row-count reconciliation report before the next phase begins. The payroll integration field mappings and workflow inventory are delivered as written documents at this stage.
Cutover, validation, and rebuild handoff
We freeze writes to the CatalystOne tenant during the cutover window, run a final delta migration of any records modified since the last sync, then enable BambooHR as the system of record. We deliver the workflow and approval rule inventory, the payroll integration mapping document, and the cross-reference table (CatalystOne Person ID to BambooHR Employee ID) to the customer's admin team. We support a five-business-day post-cutover window to resolve any data quality issues raised during the first week of BambooHR live use. We do not rebuild CatalystOne workflows or payroll integration logic inside the migration scope.
