Overview
Moving from Rival to BambooHR is a migration that begins with a coordination challenge: Rival does not publish API documentation or data export endpoints, so every migration requires requesting a platform-assisted export during scoping before we can validate and transform the source data. Once we receive the structured export (CSV or JSON), we map core employee fields to BambooHR's Employee object, resolve the organizational hierarchy as a department and reporting-line graph, and write compensation effective-date sequences as individual rows to BambooHR's Compensation module on the Elite plan. PTO balance snapshots transfer as opening balances; ongoing accruals continue post-migration. We flag document-heavy migrations upfront since binary attachments cannot be guaranteed through self-serve means and require either a platform-assisted export or manual re-upload. Custom fields discovered during scoping are mapped field-by-field with type validation before any writes execute. Workflows, onboarding task sequences, and benefits carrier-specific IDs are documented but not migrated as functional configurations; BambooHR's admin rebuilds these post-cutover.

Object mapping
Each row shows how a Rival 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.
Rival
Employee
BambooHR
Employee
1:1Core employee fields (first name, last name, hire date, job title, department, work location, employment status) map to BambooHR Employee fields. Rival's custom fields are discovered during scoping by coordinating with the customer's Rival administrator; each field is then type-mapped to a BambooHR Employee field (text, date, dropdown, checkbox) before any records write. The mapping table is built per-migration because Rival allows organizations to define arbitrary custom fields with no public schema registry.
Rival
Department
BambooHR
Department
1:1Rival stores department assignments as a related field on employee records. We extract the distinct department names during export, create corresponding Department records in BambooHR, then re-attach employees to the correct department during the employee write phase using BambooHR's departmentId field. If Rival exposes a department hierarchy (sub-departments), we build a parent-child structure in BambooHR's Department module.
Rival
Reporting Line
BambooHR
Employee Manager Field
lossyRival's manager relationships (reporting lines) are stored as a related set. We extract the manager reference per employee from the export and resolve it to the manager's Employee record in BambooHR by matching on name or email. The managerId on the BambooHR Employee record establishes the reporting line for the org chart and approval routing. Circular references are flagged during reconciliation and escalated to the customer's HR admin.
Rival
Compensation History
BambooHR
Compensation
1:1Rival stores salary and compensation records with effective dates. We preserve the effective_date sequence from Rival and map each row to BambooHR's Compensation Management module, which is available on the Elite plan. Each effective-date row writes as a separate Compensation record with pay group, pay rate, pay frequency, and change reason. If the customer does not license Elite, we write the most recent compensation as a custom field on the Employee record and document the effective-date sequence for manual entry.
Rival
PTO Balance
BambooHR
Time Off Balance
1:1Rival stores PTO as current-state balance values. We extract the balance snapshot at migration time and write it as an opening balance on BambooHR's Time Off Management for each employee. Accrual policies and ongoing balances continue in BambooHR post-migration; we set a migration-date marker so the customer's HR admin can validate that accrual resets are not double-counted. If Rival exposes accrual rate and carryover data, we include those in the opening balance write.
Rival
Benefits Enrollment
BambooHR
Benefits
1:1Benefits data (plan names, coverage tiers, enrollment dates, carrier names) migrates as structured records per employee. Carrier-specific enrollment IDs may not map 1:1 across platforms; we write the plan name and tier as text fields and flag carrier-specific IDs in the reconciliation report for the HR admin to re-enter manually. Benefits carriers and plan IDs are not verified against BambooHR's benefit module schema unless the customer licenses BambooHR's native Benefits module.
Rival
Job Title
BambooHR
Job Title
1:1Job titles are standard flat fields in Rival and map directly to BambooHR's jobTitle field on the Employee record. No transformation required. Job titles do not require a separate lookup table.
Rival
Location
BambooHR
Location
1:1Rival stores location data (office addresses, remote designations) as a flat field on employee records. We map these to BambooHR's location field, creating Location records in BambooHR's Locations module if the address data includes structured city/state/zip components. Remote designations transfer as a text value in the location field.
Rival
Custom Fields
BambooHR
Employee Custom Fields
lossyRival custom fields are customer-defined and vary by organization. During scoping, we coordinate with the customer's Rival administrator to extract the live field schema, then create matching custom fields in BambooHR before any data writes. Field types are mapped: text to Text, dates to Date, checkboxes to Checkbox, and picklist-like fields to Dropdown. Fields that do not exist in BambooHR's standard schema are created as BambooHR custom fields in the Employee module settings first.
Rival
User and Role
BambooHR
User
1:1Rival's user and role model (admin, manager, employee role types) maps to BambooHR user accounts. Role names and permission sets differ across platforms; we map Rival role types to the closest BambooHR equivalent (Employee access level) and flag any Rival custom permission sets that require manual reconfiguration in BambooHR's Access Control settings post-migration.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Rival gotchas
No publicly documented export API for self-serve data extraction
Documents and binary attachments are not exportable via standard means
Custom fields have no stable schema for automated mapping
BambooHR gotchas
Undocumented API rate limits can trigger 503 errors
Per-employee pricing model requires active record count verification
API credentials must be sent on every request to avoid extra round trips
Custom field schema varies per account and requires manual inventory
Document and attachment exports are not covered by standard report exports
Pair-specific challenges
Migration approach
Scoped discovery and export coordination
We conduct a discovery call with the customer's Rival administrator to enumerate the live employee schema, custom field list, department structure, compensation history depth, PTO policy types, and benefits enrollment scope. We simultaneously request a platform-assisted export from Rival's support team, specifying the desired format (structured CSV or JSON) and field list. If Rival cannot meet the export timeline, we escalate this as a migration blocker before any further planning. The discovery output is a written migration scope document with object list, field inventory, and a confirmed export delivery date from Rival.
BambooHR tenant setup and schema pre-creation
We provision the BambooHR destination tenant or confirm access to an existing one, select the appropriate plan tier (Core, Pro, or Elite) based on the customer's feature requirements, and pre-create all custom fields in BambooHR's Employee module settings before any data writes begin. Department records are created in BambooHR's Department module. If the customer licenses Compensation Management on Elite, we configure the pay group and compensation fields. This step ensures the destination schema is ready before the export arrives.
Export receipt, validation, and field mapping
Upon receiving the Rival export (CSV or JSON), we validate record counts, check for required field completeness (name, hire date, employment status), and identify any records with missing or malformed data. We build the per-organization field-mapping table from the discovered Rival schema to the BambooHR field types confirmed in step two. Custom field mappings are validated for type compatibility (text, date, checkbox, dropdown). Records with unmappable fields are flagged in a reconciliation report for the customer's HR admin to resolve before the migration write phase.
Sandbox migration and admin reconciliation
We run a full migration into a BambooHR sandbox environment using production-like data volume. The customer's HR lead spot-checks 25-50 employee records for field accuracy, verifies department assignments, confirms manager reporting lines, and validates compensation and PTO balance snapshots against the Rival source data. The customer signs off the sandbox results before the production migration write phase begins. Any mapping corrections identified during sandbox are applied to the production migration script before execution.
Production migration in dependency order
We run production migration in the correct dependency sequence: Departments (created first), Locations, Employees with managerId resolved and custom fields mapped, PTO balance snapshots as opening balances, Compensation records (Elite plan) with effective-date sequence, and Benefits enrollment data. Each phase emits a row-count reconciliation report. Document re-association guidance is delivered as a separate artifact; binary files require manual re-upload to BambooHR's document module or a platform-assisted export from Rival if available.
Cutover, validation, and workflow handoff
We freeze Rival write access during the cutover window, run a final delta migration of any records modified during the migration window, then enable BambooHR as the system of record. We deliver a written inventory of Rival onboarding task sequences, workflow configurations, and benefits carrier-specific IDs that require manual rebuild in BambooHR. We support a one-week hypercare window for reconciliation issues. We do not rebuild Rival workflows or onboarding sequences as BambooHR workflows; that is a separate engagement or an internal admin task.
