Overview
Moving from isolved to BambooHR is a data-remapping migration rather than a platform upgrade or consolidation. isolved organizes its HRMS around core Employee records with nested Pay Groups, Job Codes, Work Locations, and Pay Types as employer-defined picklists; BambooHR uses a flatter Employee record model with fewer configuration layers and a cleaner API surface. We export from isolved via batch file through the partner ecosystem (isolved has no publicly documented REST endpoint), re-code deduction and garnishment schemas for SSAE-18 audit continuity, and map every defined-list value to BambooHR's corresponding picklist. Historical payroll registers, active benefit elections, and time-off balances migrate as structured line items; Direct Deposit accounts transfer under encryption. We do not migrate isolved Workflow rules, benefit administration configuration, or talent acquisition module data as code; we deliver a written inventory of these for the customer's BambooHR admin to rebuild.

Object mapping
Each row shows how a isolved 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.
isolved
Employee
BambooHR
Employee
1:1isolved Employee records map directly to BambooHR Employee. Core fields (first name, last name, SSN, date of birth, hire date, adjusted service date, employment status, marital status, address, and contact information) transfer via batch CSV. SSN is extracted under encryption and re-masked before import into BambooHR. Employee number in isolved maps to BambooHR's employeeId field. Employment category, citizenship, and ethnicity fields map to BambooHR custom fields or standard fields with appropriate picklist selection.
isolved
Pay Groups
BambooHR
Pay Frequency
lossyisolved Pay Groups (weekly, biweekly, semi-monthly, monthly) control pay frequency and overtime calculation rules. We extract the Pay Group table and map each group to BambooHR's Pay Frequency setting (stored as a period type: weekly, bi-weekly, semi-monthly, monthly). If BambooHR's Payroll add-on is active, Pay Frequency also drives the payroll run calendar. Pay Groups with custom overtime rules do not migrate as configuration; we document the overtime threshold for the customer's admin to configure in BambooHR Payroll settings.
isolved
Job Codes
BambooHR
Job Title or Department (custom picklist)
lossyisolved Job Codes are an employer-defined picklist used for compliance reporting, compensation rules, and headcount analysis. BambooHR does not have a native Job Code object; we map Job Code values to a BambooHR custom picklist field (e.g., jobCode) and export the full isolved Job Code table during scoping to produce a mapping matrix. The customer reviews the matrix and assigns each isolved code to a BambooHR Job Title or creates a new Department entry as appropriate.
isolved
Work Locations
BambooHR
Location
lossyisolved Work Locations drive tax withholding, workers comp codes, and benefit eligibility rules. BambooHR uses a Location field on the Employee record to capture work site. We export the full isolved Work Location list and map each location to a BambooHR Location entry (State and Country fields), preserving any workers comp code association in a custom field for the customer's admin to configure in BambooHR's workers comp settings post-migration.
isolved
Pay Types
BambooHR
Pay Rate or custom compensation field
lossyisolved Pay Types (salary, hourly, commission, bonus, and deduction codes) are defined lists that vary by employer. BambooHR stores compensation as a Pay Rate field on the Employee record with separate fields for pay type. We extract the isolved Pay Type table and map each code to a BambooHR payType value (salary, hourly, nonexempt). Custom deduction codes and employer benefit contribution codes that do not have direct BambooHR equivalents are documented in a compensation schema handoff for the customer's admin to set up in BambooHR Payroll.
isolved
Payroll History
BambooHR
Payroll Records (custom export)
1:1Historical payroll registers (earnings, taxes, deductions, garnishments) migrate as a structured data export. We extract full payroll history from isolved's batch file format by Pay Group and pay period, preserving pay-period dates, earnings amounts, tax withholdings, deduction codes, and garnishment order details. SSAE-18 audit continuity requires that W-2 reportable amounts and garnishment order identifiers remain auditable after cutover; we re-code deduction schemas to align with the destination format and deliver a payroll register CSV for the customer's records. Note that BambooHR Payroll does not store historical payroll registers as a native object; the data migrates as an exported dataset for record-keeping rather than for display inside BambooHR.
isolved
Benefit Enrollments
BambooHR
Benefits (custom export)
1:1Active benefit elections (medical, dental, vision, HSA, FSA, life insurance) link to Employee records in isolved. We extract enrolled plan names, carrier names, coverage tiers (employee, spouse, family), and monthly premiums. BambooHR tracks benefit elections as a structured module with plan enrollment records linked to Employees. We map enrolled plans to BambooHR Benefit Plan entries and flag any plan types (such as Section 125 cafeteria plan elections) that require manual reconfiguration in BambooHR's benefit settings because plan-level admin rules do not migrate.
isolved
Time Off Balances
BambooHR
Time Off
1:1Accrued and taken time off by type (PTO, sick, personal, and custom accrual types) migrate as current balances and carry-forward amounts. isolved calculates accruals per Work Location and Pay Group rules; we export the balance snapshot as of the migration date and import it into BambooHR Time Off as the opening balance. Note that accrual rate rules (such as years-of-service step increases) do not migrate as configuration; we document the current accrual rates for each Time Off type and leave the rule configuration to the customer's BambooHR admin.
isolved
Direct Deposit Accounts
BambooHR
Direct Deposit
1:1Employee banking information for payroll disbursement migrates under encryption. We extract routing number, account number, deposit type (full or partial), and deposit amount or percentage fields from isolved's Direct Deposit transactions. Bank account data is masked in transit and only decrypted at the point of import into BambooHR. Note that BambooHR recommends that employees re-enter banking details during onboarding as a security best practice; we flag this to the customer during scoping so they can decide whether to import with re-authentication required or to proceed with the import and notify employees.
isolved
Documents
BambooHR
Files
1:1Electronically stored employee file attachments (offer letters, performance reviews, I-9s, signed agreements) migrate as document blobs with metadata. We export documents from isolved's file storage and import them into BambooHR's Files section linked to the corresponding Employee record. Document filenames, upload dates, and file types (PDF, DOCX, image) are preserved in BambooHR's metadata. Note that we cannot guarantee format fidelity for files created in legacy formats or with embedded macros; we recommend spot-checking a sample of 20 documents post-migration.
isolved
Workflow Transactions
BambooHR
N/A (flagged for admin review)
1:1Pending or in-flight change requests in isolved (salary changes, direct deposit updates, name or address changes, HSA elections) are stateful records that do not auto-resolve on import. We extract pending transaction records with their current status, transaction type, and effective date, and deliver them as a transaction queue CSV. The customer's BambooHR admin reviews and completes each transaction manually post-migration since BambooHR's workflow model does not accept imported pending states.

Migration approach
Discovery and batch export from isolved
We audit the customer's isolved environment: employee count (active and inactive), Pay Group table, Job Code list, Work Location list, Pay Type list, payroll history depth (current year or multi-year), active benefit plan enrollments, time-off accrual balances, direct deposit records, and any pending workflow transactions. We also identify the isolved HRO or PEO partner managing the account and coordinate the batch file export from isolved's system. This step produces a data inventory spreadsheet that the customer reviews and signs off before extraction begins.
BambooHR environment setup and custom field configuration
We configure the destination BambooHR account in parallel with the source extraction. This includes provisioning custom picklist fields for Job Codes, Pay Types, Workers Comp codes, and any isolved fields that have no BambooHR standard equivalent. We set up Location entries corresponding to each isolved Work Location, configure the Pay Frequency for each isolved Pay Group, and enable the BambooHR Payroll add-on if the customer is moving payroll processing. If the customer uses BambooHR's ATS add-on for talent acquisition, we configure job opening structures at this stage.
Defined-list remapping matrix
We export the full isolved picklist tables (Job Codes, Pay Types, Work Locations) and produce a mapping matrix. The customer reviews each value and assigns it to a BambooHR picklist entry or creates a new one. This step is the primary dependency for the employee record import because no record can land with a null classification code. We run the mapping matrix through a dry-run validation to flag any unmapped values before proceeding.
Payroll history and benefit enrollment extraction
We extract historical payroll registers from isolved in structured CSV batches by Pay Group and pay period. Deduction codes are re-coded to a standard schema for audit continuity. Active benefit elections are extracted with plan names, carriers, coverage tiers, and premium amounts. Garnishment orders are extracted with order identifiers, deduction amounts, and frequency so that ongoing deductions remain traceable in the customer's records. All payroll data is encrypted in transit and stored in a secure staging environment for import.
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 in, benefit enrollments in, time-off balances in, payroll snapshots in) and spot-checks a random sample of 25-50 records against the isolved source. Any mapping corrections, missing picklist values, or data quality issues (duplicate SSNs, malformed addresses, missing hire dates) are resolved in this phase before production migration begins.
Production migration in dependency order
We run production migration in record-dependency order: Locations (from Work Locations), Employees (with Job Code, Pay Type, and Pay Frequency mapped), Direct Deposit (under encryption), Time Off balances (opening balances by type), Benefit enrollments (with plan and coverage tier linked), and Payroll history (structured export for record-keeping). Each phase emits a row-count reconciliation report. Direct Deposit import is the last data-import phase before cutover to minimize the window during which banking information sits in the destination system.
Cutover, validation, and handoff
We freeze writes in isolved during cutover, run a final delta migration of any records modified during the migration window, then enable BambooHR as the system of record. We deliver the defined-list mapping matrix, the pending workflow transaction queue, the accrual rate documentation, and the payroll history export archive. We support a one-week hypercare window to resolve any data quality issues raised by the HR team. We do not rebuild isolved Workflow rules, benefit administration configuration, or talent acquisition module data as BambooHR configuration; these are separate handoff items for the customer's admin.
