Overview

What this migration involves

IceHrm and BambooHR take different architectural approaches: IceHrm is modular by design with separate administration panels for each module, while BambooHR consolidates employee data into a single core record with tabbed sections for job info, time-off, and benefits. We resolve that structural difference by mapping IceHrm module data into BambooHR's unified employee model, splitting module-specific fields into BambooHR's designated sections. Self-hosted IceHrm instances add complexity because customers can modify the PHP/MySQL schema directly, so we always audit the deployed schema before field mapping begins. We do not migrate IceHrm workflows, automation rules, or payroll configuration; these require rebuilding or reconfiguring inside BambooHR post-migration.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

AI proposes the map; you confirm before any record moves.

Relationships preserved

Parent–child, lookups, and ownership stay linked.

Full activity history

Calls, emails, meetings — with original timestamps.

Attachments & notes

Documents, uploads, and inline notes move with the record.

Why teams make this switch

Two sides of the same decision

Leaving

IceHrm

What's pushing teams away

  • Support responsiveness is a recurring complaint — multiple reviews cite support staff who lack deep product knowledge, causing delays when configuration issues arise.
  • The learning curve for understanding how IceHrm modules interrelate and where specific settings live is steep enough to generate friction during onboarding and configuration.
  • Organizations that scale beyond the SMB tier often find IceHrm lacks the advanced HCM features, reporting depth, or compliance controls available in enterprise platforms like Workday or BambooHR.
  • Teams without in-house developer resources struggle with the self-hosted version's maintenance burden — server updates, database backups, and extension management fall on the customer.

Choosing

BambooHR

What's pulling them in

  • Lowest friction entry point for SMBs moving off spreadsheets — intuitive interface means most teams are functional within days, not weeks.
  • Consolidation value: BambooHR merges ATS, onboarding, HR records, time-off, and payroll into a single pane of glass that employees never need to leave.
  • Volume discounts applied automatically by headcount, so pricing scales predictably as the company grows without renewal negotiations.
  • BambooHR reports most customers go live in four to six weeks, making it a realistic commitment for under-resourced HR teams.
  • Award-winning Support Heroes cited frequently in reviews — responsive human support after implementation is a differentiator.

Object mapping

How IceHrm objects map to BambooHR

Each row shows how a IceHrm 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.

IceHrm

Employee

maps to

BambooHR

Employee Record

1:1
Fully supported

IceHrm Employee records map to BambooHR Employee. IceHrm stores personal info, employment details, qualifications, and emergency contacts in one record; we split these into BambooHR's personal info section, job info tab, and employment details. Employee number, hire date, termination date, employment status, and EEO job category transfer as typed fields. Custom fields discovered per-module are added to the Employee record as BambooHR custom fields with options extracted from the IceHrm picklist values.

IceHrm

Department / Job Title / Organization Structure

maps to

BambooHR

Departments and Employment Fields

lossy
Fully supported

IceHrm departments, job titles, employment types, and branch/office structures map to BambooHR's department list and job information fields. IceHrm's multi-office support (with country and branch) maps to BambooHR's location field. We run a department and title discovery step to capture the full taxonomy before import and create BambooHR departments and locations in advance of the employee import.

IceHrm

Leave / Time-off

maps to

BambooHR

Time-Off

1:1
Fully supported

IceHrm Leave module stores balances, approval workflows, accrual rules, and leave request history. Each leave type in IceHrm (Annual, Sick, Personal, etc.) maps to a corresponding BambooHR time-off policy. We preserve leave balances as BambooHR accrued amounts and map the leave request status workflow to BambooHR's time-off request states. Accrual rules and carry-over configurations require the customer to define BambooHR equivalent policies post-migration.

IceHrm

Time & Attendance

maps to

BambooHR

Time Tracking (if add-on)

1:1
Fully supported

IceHrm punch-in/out records, timesheets, and overtime calculations map to BambooHR time tracking entries if the customer has purchased BambooHR's Time Tracking module. We transfer clock-in and clock-out timestamps, timesheet hours, and overtime flags. Overtime rules and accrual policies do not migrate and require manual configuration in BambooHR.

IceHrm

Payroll

maps to

BambooHR

Compensation History (Employee Job Info)

1:1
Mapping required

IceHrm payroll stores salary components, pay schedules, and payroll run history. BambooHR stores current compensation (pay rate, pay frequency, change reason) on the Employee record's compensation tab but does not replicate payroll run history. We migrate current salary, pay frequency, and salary change reason to BambooHR's compensation fields. Full payroll run history (prior pay periods, deductions, net pay) does not have a direct BambooHR equivalent and is delivered as a CSV export for the customer's records.

IceHrm

Recruitment / Applicant Tracking

maps to

BambooHR

Applicant Tracking (BambooHR ATS add-on)

1:1
Fully supported

IceHrm Recruitment stores job postings, applicants, application stages, and pipeline data. These map to BambooHR's Applicant Tracking system if the customer purchases it. Job postings map to BambooHR Jobs, applicants map to Candidates with application status mapped from IceHrm stages. Custom pipeline stages require explicit mapping to BambooHR's application status options during scoping.

IceHrm

Performance Reviews

maps to

BambooHR

Performance Management (Pro and Elite tiers)

1:1
Fully supported

IceHrm peer-to-peer review templates, review cycles, ratings, and comments migrate to BambooHR Performance Management on Pro and Elite plans. Review records and scores transfer to BambooHR review cycles. Custom review templates are documented and delivered with field mapping notes for the customer's admin to rebuild as BambooHR review forms. 360-degree review structures map to BambooHR's review cycle configuration.

IceHrm

Training / Learning Management

maps to

BambooHR

Training Tracking

1:1
Fully supported

IceHrm Training tracks courses, enrollments, completion records, and learning paths per employee. These map to BambooHR's training records attached to the Employee. Course catalog data migrates as BambooHR training entries with completion status and dates. BambooHR does not have a native LMS; learning path sequences and course content require manual rebuild or a separate LMS platform.

IceHrm

Documents

maps to

BambooHR

Employee Files

1:1
Mapping required

IceHrm employee documents (contracts, certifications, ID scans) are stored as file attachments per module. We extract documents file-by-file from the IceHrm database or web interface, preserve the file name, MIME type, and upload date, and import them into BambooHR's Employee Files section under the corresponding category. Document content does not migrate as searchable text; files are preserved as binary attachments.

IceHrm

Custom Fields

maps to

BambooHR

Custom Fields

1:1
Mapping required

IceHrm allows custom fields on selected modules with independent schemas per module. We discover all custom fields across every active module during the pre-migration audit, extract picklist option values, and map them to equivalent BambooHR custom fields with matching types and option sets. If a custom field references a lookup to another record (e.g., employee-to-manager), we resolve the lookup at migration time and store the reference as a BambooHR dropdown or relationship field.

IceHrm

Expense Requests

maps to

BambooHR

No direct equivalent

lossy
Mapping required

IceHrm's Expenses module stores expense requests with approval statuses and custom fields. BambooHR does not have a native expense tracking module. We export expense records as a structured CSV with all fields, statuses, and amounts preserved. The customer decides whether to import the CSV for record purposes or use a separate expense management tool.

Pair-specific challenges

  • Self-hosted schema modifications cause migration surprises

    IceHrm's self-hosted version runs on PHP and MySQL, and customers with developer access can modify the database schema directly — adding columns, changing field types, or creating custom tables. When we migrate from a self-hosted instance, we discover the actual deployed schema during the audit phase and adjust field mappings accordingly. We do not assume the schema matches the upstream release. If the customer has added custom PHP code or modified core tables, we flag those modifications before writing a single record to BambooHR.

  • Employee count billing model on IceHrm Cloud

    IceHrm Cloud bills based on total employee count with a flat fee structure. When migrating out of IceHrm Cloud, customers may be paying for seats they are not actively using. We audit the live employee roster during scoping and flag inactive or terminated employees that the customer may want to exclude from the migration and from BambooHR onboarding, which affects downstream seat count and billing on BambooHR's per-employee model.

  • Custom fields per module require manual field-level discovery

    IceHrm allows custom fields to be added to individual modules independently, so the same module (e.g., Employees) may have different custom field schemas across two IceHrm instances. We run a custom field discovery step per module before mapping begins, capturing all extended attributes and picklist values. This discovery step adds time to the scoping phase but prevents field mapping errors at import time.

  • Document attachment export requires file-by-file handling

    Employee documents in IceHrm — contracts, certifications, ID scans — are stored as file attachments linked to employee records. There is no bulk file export endpoint, so we extract documents individually via the web interface or file system access on self-hosted instances. We preserve the file name, MIME type, upload date, and link to the employee record. BambooHR's Employee Files section must have matching categories configured before document import begins.

  • BambooHR date input format must match IceHrm source dates

    BambooHR allows different date input formats configured in Admin Console under Settings > Account > General Settings > Date Input Format. IceHrm stores dates in its own MySQL format. If the source IceHrm instance uses a different date format than the BambooHR account's configured format, date fields will import incorrectly. We verify both formats during scoping and apply a date reformat step before any import to BambooHR.

Migration approach

Six steps for a successful IceHrm to BambooHR data migration

  1. Instance audit and schema discovery

    We audit the IceHrm instance (cloud or self-hosted) across all active modules: Employees, Leave, Time & Attendance, Payroll, Recruitment, Performance Reviews, Training, Documents, and Custom Fields. For self-hosted instances, we connect to the MySQL database directly to capture the actual deployed schema including any custom columns or modified table structures. For cloud instances, we use the REST API endpoints and Admin export tooling. The audit output is a written schema map showing every source field, its IceHrm module, its data type, and whether it is standard or custom.

  2. Data quality review and cleanup scoping

    We review IceHrm employee records for duplicates, missing required fields, and inconsistent data (e.g., employees with no hire date, terminated employees with active leave balances). We flag records that need cleanup before import and provide the customer with a data quality report. HR data tends to include more inconsistently maintained fields than transactional data, so we work with the customer's HR admin to resolve critical gaps before migration begins.

  3. BambooHR configuration and custom field provisioning

    We configure BambooHR before any data import: departments and locations are created to match the IceHrm organization structure, time-off policies are defined to cover IceHrm leave types, and custom fields are provisioned in BambooHR with types and picklist options matched to IceHrm. This configuration happens in the customer's live BambooHR account or a sandbox if the customer requests a staging validation run first.

  4. Employee and organizational record migration

    We migrate employee records first, as all other module data depends on the employee as the parent record. We import in dependency order: employee records with job info and compensation, then departments and locations if not pre-created, then organizational hierarchy (reporting manager relationships resolved by email or employee number match). Each phase emits a row-count reconciliation report before the next phase begins.

  5. Leave, time tracking, and payroll data migration

    With employee records established, we migrate leave balances and accrual amounts, time-off request history, time tracking entries, and payroll compensation snapshots. Leave request workflow history migrates as a record of past requests with status; active pending requests require the customer to decide whether to re-create them in BambooHR or close them out in IceHrm before cutover. Payroll run history is exported as a CSV if the customer requires it for records, since BambooHR does not store historical payroll runs.

  6. Document import and custom field population

    We import employee documents file-by-file into BambooHR's Employee Files section under the corresponding employee. Documents are matched to employees by employee ID or email. After document import, we populate custom fields on each employee record using the options extracted during schema discovery. We verify custom field completeness against the audit map before closing the migration.

  7. Cutover, validation, and rebuild handoff

    We freeze IceHrm writes during cutover and run a final delta migration of any records modified during the migration window. We deliver a reconciliation report comparing record counts in IceHrm against BambooHR by object type. We provide a written inventory of IceHrm workflows, automations, and approval rules that require rebuild in BambooHR, along with guidance on mapping leave accrual policies, time tracking rules, and review templates. We support a one-week post-go-live window for reconciliation issues.

Platform deep dives

Context on both ends of the pair

IceHrm logo

IceHrm

Source

Strengths

  • Fully open-source with source-code access on GitHub, giving teams complete control over the codebase and hosting environment.
  • Modular architecture allows activating only needed HR modules, reducing system complexity for smaller teams.
  • Cloud tier pricing is aggressively low at $12/month for up to 6 employees, making it accessible for micro-SMBs and early-stage companies.
  • Both cloud and self-hosted deployments share the same feature set, enabling a low-risk migration path from managed to self-hosted.
  • Covers the full core HRMS surface area: employee management, leave, attendance, payroll, recruitment, performance reviews, and training.

Weaknesses

  • Support quality is inconsistent — reviewers report support staff with limited product knowledge and slow response times on complex issues.
  • The learning curve is steep for non-technical HR administrators who need to understand how modules interconnect and where settings live.
  • API documentation is not publicly prominent, limiting the availability of structured, programmatic export options for large-scale data extraction.
  • Enterprise-grade features — advanced analytics, compliance automation, global payroll — are absent or underdeveloped compared to HCM platforms like BambooHR or Workday.
  • Self-hosted deployments require in-house server maintenance, database management, and update handling, which is a significant hidden cost for teams without developer resources.

BambooHR

Destination

Strengths

  • Single platform consolidating ATS, onboarding, HR records, payroll, and time-off reduces system sprawl for SMBs.
  • Fast implementation — BambooHR reports four to six weeks from kickoff to go-live for most customers.
  • Per-employee pricing with automatic volume discounts makes cost predictable as headcount grows.
  • Strong customer support reputation (Support Heroes) cited consistently across G2, Capterra, and direct testimonials.
  • Well-documented API with UTF-8 encoding, clear field types, and HTTPS-only access.

Weaknesses

  • Mobile application is significantly limited compared to the desktop experience, frustrating remote and field workers.
  • Companies above 150–200 employees frequently outgrow the platform's feature depth and customization surface.
  • Limited advanced reporting and analytics compared to enterprise HR platforms — custom report building is the ceiling.
  • PTO and profile customization are pain points — non-standard accrual policies and complex org structures require workarounds.
  • Document management and attachment handling lack the granularity of dedicated document-centric HR systems.
