Overview
Moving from Grove HR to BambooHR is a file-to-API migration rather than an API-to-API migration. Grove HR does not publish a documented REST API for external data extraction, so we work with CSV and XLS exports generated from within the product, validated against a prepared data dictionary before loading into BambooHR via its REST API. Grove HR organises leave entitlements around UK employment law with Bradford Factor calculations and statutory pay tools that BambooHR does not natively replicate; we map those entitlement values as static snapshot balances rather than live policy rules. Onboarding and offboarding checklists are Grove template-bound structures that we decompose into standalone employee tasks in BambooHR. We do not migrate automated workflows, recruitment sequences, or performance review templates as code; we deliver a written inventory of every automation for the customer's admin to rebuild in BambooHR.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a Grove HR 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.
Grove HR
Employee
BambooHR
Employee
1:1Grove HR Employee records map directly to BambooHR Employee records. Core fields (first name, last name, date of birth, address, contact details, employment status, job title, start date, department) migrate via CSV export to BambooHR REST API. We resolve Grove's nested document references to separate attachment assets and link them to the corresponding BambooHR Employee record after the employee insert completes. Any custom fields defined on Employee in Grove are detected during scoping, and we map them to BambooHR custom fields on the Employee tab. Grove employee IDs are preserved in a custom BambooHR field grove_employee_id__c for audit trail purposes.
Grove HR
Leave / Time Off
BambooHR
Time Off
lossyGrove HR leave entitlements (annual leave, sick leave, parental leave) export as balance snapshots per employee per leave type. These map to BambooHR Time Off types with balances entered as static values at migration time. Grove's dynamic accrual rules (accrual rate, carry-over limits, Bradford Factor triggers) are not replicated in BambooHR; instead, we capture the current entitlement and used balance as a fixed snapshot and the customer's BambooHR admin configures accrual rules going forward. Any approved leave between extraction and go-live requires a supplemental import or manual adjustment to avoid double-counting.
Grove HR
Onboarding Checklist
BambooHR
Onboarding Tasks
1:manyGrove HR onboarding is driven by automated checklist templates assigned to employees with task assignments and completion states. Templates are defined at the company level and cannot be exported as reusable objects. We export each assigned checklist item as a standalone task record per employee, capturing task name, assignee, due date relative to start date, and completion status. Completed items migrate as completed tasks; incomplete items migrate as open tasks. The customer's BambooHR admin rebuilds reusable onboarding packet templates from the delivered task list inventory.
Grove HR
Offboarding Checklist
BambooHR
Offboarding Tasks
1:manyGrove HR offboarding checklists follow the same template-to-task decomposition as onboarding. We extract each assigned offboarding task per employee with completion status and link it to the termination record. Template structure (task names, order, assignee roles) is preserved as a flat task list in the migration deliverable for the customer's admin to reconstruct as BambooHR offboarding workflows. Grove's termination reason and exit interview data migrate as notes attached to the employee record.
Grove HR
Recruitment / Candidate
BambooHR
Applicant Tracking (Jobs + Applicants)
1:1Grove HR recruitment includes a career site builder, CV storage, and a drag-and-drop hiring pipeline. Candidate records, applications, and pipeline stage history are exportable from Grove HR. We map candidates to BambooHR Applicants and map Grove pipeline stages to BambooHR Job stages. Stage names vary by organisation so we capture the customer's specific stage labels during scoping and configure matching values in BambooHR before import. CV files migrate as attachments to the corresponding BambooHR Applicant record.
Grove HR
Performance Review
BambooHR
Performance Review
1:1Grove HR performance review cycles contain structured rating fields and reviewer assignments per employee. We export completed review records with scores, comments, and reviewer metadata. In-progress reviews migrate as draft reviews in BambooHR with a note flagging their incomplete status. Review templates from Grove HR do not export as reusable objects; we deliver a template inventory document describing each review cycle's structure for the customer's BambooHR admin to rebuild.
Grove HR
Goal
BambooHR
Goal
1:1Goals linked to employees with progress tracking and due dates export from Grove HR with current status, owner, and linked key results. We map goal records to BambooHR Goals, preserving the goal title, description, progress percentage, due date, and owner assignment. Orphaned goals without an active owner employee are flagged in the migration report and held for the customer's admin to reassign or close.
Grove HR
Training Record
BambooHR
Training
1:1Training modules and employee completion records export from Grove HR with assignment, completion status, and scores per employee. We map these to BambooHR Training records, preserving the course name, completion date, score (if applicable), and status. Training course content does not migrate; enrollment and completion history does. The customer's BambooHR admin rebuilds training course content separately if needed.
Grove HR
Time & Attendance
BambooHR
Time Off + Timesheets
1:1Grove HR time attendance data links to payroll calculations with clock-in/out events, timesheets, and overtime flags. Where attendance data feeds into leave entitlement computation, we export raw timesheet records as a reference dataset rather than a live integration. BambooHR does not have a native clock-in/out module, so timesheet records are stored as an attached reference file on the employee record or mapped to a BambooHR custom field if the customer configures one. Overtime flags migrate as a custom field on the employee.
Grove HR
Document (Contract, Payslip)
BambooHR
Employee File
1:1Employee documents (contracts, payslips, offer letters) export from Grove HR as binary file attachments. We export these as separate file assets with a reference back to the owning employee, then attach them to the corresponding BambooHR Employee record using the BambooHR file upload API. We do not parse or transform document contents. The customer should confirm BambooHR's file storage limits for their plan before committing to a full document migration; BambooHR imposes storage limits that vary by tier.

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.
Grove HR gotchas
No public API documentation means migrations are file-based
Leave balance accuracy at cutover requires manual verification
Onboarding and offboarding checklists are template-bound
Payslip and contract documents export as binary blobs
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
Scoping and data dictionary preparation
We audit the Grove HR instance to identify all object types in use, custom field definitions, leave policy configurations, onboarding template structures, and recruitment pipeline stages. Because Grove HR lacks a documented API, we work with the customer to generate CSV and XLS exports from within the product. We prepare a data dictionary mapping Grove field names to the expected BambooHR field names, flagging any naming inconsistencies and custom fields that require pre-creation in BambooHR. The scoping output is a written migration scope document listing all objects, record counts, and custom field mapping requirements.
BambooHR schema pre-configuration
Before any data loads, we create all required BambooHR objects and fields including custom fields on the Employee tab, Time Off types matching the Grove leave policy, Job stages for the applicant tracking pipeline, and any custom fields needed to hold Grove-specific data (grove_employee_id__c, original leave entitlement values). We configure BambooHR Time Off policies to match the leave types and accrual frequencies the customer uses in Grove, understanding that BambooHR accrual rules will apply going forward from the migration date rather than retroactively replicating Grove's policy logic.
File extraction, validation, and transformation
The customer generates exports from Grove HR (Employee list, Leave balances, Onboarding checklist assignments, Offboarding checklist assignments, Recruitment candidates and pipeline history, Performance review records, Goal records, Training records). We validate each export file against the data dictionary, flagging missing required fields, duplicate records, and inconsistent date formats. Any records with missing mandatory fields (for example, employees without a start date or department) are held in a correction queue for the customer's Grove HR admin to complete before migration proceeds.
Employee and dependency migration
We migrate in dependency order: Department and Location records first (if applicable), then Employee records with grove_employee_id__c populated, then Time Off balances as static snapshots, then document attachments uploaded per employee. Leave balances are entered as manual balance values in BambooHR Time Off rather than as live accrual calculations. Onboarding and offboarding task lists are decomposed from Grove templates and created as individual tasks linked to the corresponding employee record in BambooHR.
Recruitment, performance, and goal migration
Recruitment candidates and pipeline stage history migrate from Grove HR to BambooHR Applicants and Job stages. CV and application document attachments upload separately via the BambooHR file API. Performance review records (completed and in-progress) migrate to BambooHR Performance Reviews, with in-progress reviews flagged as drafts. Goal records migrate with progress percentage, due date, and owner preserved. Training completion records migrate with course name, completion date, and status.
Cutover, delta migration, and automation handoff
We freeze writes in Grove HR during cutover, run a final delta export capturing any records modified during the migration window, apply a supplemental import to BambooHR, then enable BambooHR as the system of record. We deliver a written inventory of every Grove HR onboarding template, offboarding template, recruitment workflow, and performance review cycle structure for the customer's BambooHR admin to rebuild. We do not rebuild automated workflows as code. We support a one-week post-go-live window for reconciliation issues.
