Overview
Aperio to BambooHR is a migration from a performance-management-focused tool to an all-in-one HRIS. Aperio holds review cycles, goal hierarchies, competency ratings, and development plans that BambooHR's standard schema does not replicate natively. We extract all Aperio data via CSV export, map employees directly to BambooHR Employee records, store performance review ratings and goals in custom fields, and reconstruct goal parent-child relationships from Aperio's flattened goal_id and parent_goal_id columns. The migration scope does not include Aperio review templates, competency library reconfiguration, or development plan workflows because these are configuration artifacts rather than data records. BambooHR's implementation typically runs four to six weeks; CSV-only extraction from Aperio adds discovery and manual field reconciliation time that pushes most Aperio migrations to six to eight weeks.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Aperio 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.
Aperio
Employee
BambooHR
Employee
1:1Aperio employee records map directly to BambooHR Employee. We extract standard fields (first name, last name, email, title, department, manager, hire date, employment status) from the Aperio CSV export and load via BambooHR API or bulk CSV import. Employee ID from Aperio maps to employeeNumber in BambooHR for deduplication. Any Aperio employee record missing a work email is flagged before import because BambooHR requires a valid work email for API-based provisioning.
Aperio
Department
BambooHR
Department
1:1Organizational structure exports from Aperio as department records with optional parent-department relationships. We map department names directly to BambooHR's Department table, preserving hierarchy where present. Departments must exist in BambooHR before employee import so that the department assignment on each Employee record is valid at insert time.
Aperio
Job Title
BambooHR
Job Title
1:1Job titles export from Aperio and map to BambooHR's Job Title field on the Employee record. BambooHR stores job titles as a flat list associated with the Employment Info tab; there is no separate job title object. Titles used in Aperio review templates as rating criteria are preserved as-is and will need to be re-established in BambooHR's review structure if the Elite Performance add-on is active.
Aperio
Performance Review
BambooHR
Employee (custom fields)
lossyAperio performance reviews are cycle-based records with ratings against competencies and goals, reviewer comments, and overall scores. BambooHR's Elite Performance add-on supports review cycles but does not replicate Aperio's exact review schema. We extract all review data from Aperio CSV and store ratings, scores, and reviewer comments in BambooHR custom fields on the Employee record. The Aperio review cycle name and period map to a custom text field so that historical review context is preserved. If the customer activates BambooHR Performance, review cycles are rebuilt manually by the admin.
Aperio
Review Cycle
BambooHR
Employee (custom fields)
lossyAperio review cycles define the temporal window for batches of reviews including start and end dates, status, and associated templates. We export cycle metadata and store cycle names and periods as custom fields on the Employee record alongside the review ratings. BambooHR's native Performance module (Elite tier) uses its own review cycle concept that is not automatically populated from this data; the customer rebuilds cycles in BambooHR Performance if that module is active.
Aperio
Review Template
BambooHR
Not migrated
1:1Aperio review templates define the structure of reviews including competency sections, rating scales, and mandatory field requirements. Templates are configuration artifacts rather than data records. We do not migrate templates as code because they reference Aperio-specific competency libraries and rating logic that do not map directly to BambooHR's template builder. We deliver a written inventory of all active Aperio templates with their section breakdown and rating scales for the customer's admin to rebuild in BambooHR Performance.
Aperio
Competency
BambooHR
Not migrated
1:1Aperio competency libraries define the rating criteria used within reviews and templates. Competencies are reference data with no direct equivalent in BambooHR's standard schema. We extract competency definitions and ratings as part of the review data migration and store them in custom fields. Any custom competencies require manual reconfiguration in BambooHR Performance if the customer uses the Elite add-on.
Aperio
Goal
BambooHR
Employee Goal custom fields
1:1Aperio goals export as flat CSV records with goal_id and parent_goal_id columns representing the hierarchy. We extract all goal records, reconstruct parent-child links by pairing goal_id with parent_goal_id, and store goal text, status, due date, and the parent goal reference as custom fields on the Employee record. Orphaned goals (where the parent_goal_id does not exist) and circular references are flagged for customer resolution before loading.
Aperio
Goal Hierarchy
BambooHR
Custom field structure
lossyAperio's nested goal structure flattens in CSV export to parent_id fields. We process the export to extract all goal_id and parent_goal_id pairs, validate that each parent reference resolves to an existing goal, and reconstruct the hierarchy by storing parent goal text in a custom field on each child goal. The goal hierarchy cannot be represented natively in BambooHR because there is no parent-child goal object; the flattened representation in custom fields preserves the relationship for reference.
Aperio
Development Plan
BambooHR
Document attachment or custom fields
lossyAperio development plans track growth actions linked to employees, often tied to review outcomes, with milestones and timelines. BambooHR has no native development plan object. We extract development plan records and their associated milestones, storing plan text and key milestone dates as custom fields on the Employee record. Supporting detail documents are attached as file uploads to the employee profile.
Aperio
Custom Field
BambooHR
Custom Field
lossyAperio custom fields on Reviews, Goals, and Development Plans contain picklist and multi-select values that differ from Aperio defaults. These do not self-document in the CSV export. We identify all active custom fields during discovery, export sample values, and map them to BambooHR custom fields by type. Where value sets differ significantly between Aperio and BambooHR picklists, we flag the discrepancy for customer resolution before loading and document the value mapping in the migration spec.

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.
Aperio gotchas
No public API means CSV-only migration exports
Goal parent-child hierarchies export as flat records
Custom fields require manual value-set 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

Migration approach
Discovery and Aperio CSV export scoping
We audit the Aperio instance to identify all active record types: Employees, Departments, Job Titles, Review Cycles, Performance Reviews, Review Templates, Competencies, Goals (with hierarchy depth), Development Plans, and any active custom fields. We coordinate with the customer to generate CSV exports for each object type, verify export completeness against record counts in the Aperio UI, and flag any export columns that are truncated or missing. This phase produces a written data inventory and a CSV field catalog for mapping.
BambooHR schema preparation and custom field design
We assess the customer's BambooHR tier (Core, Pro, or Elite) and determine whether the Performance add-on is active. We design the destination schema: standard employee fields are mapped directly, custom fields are created in BambooHR for all review ratings, goal data, development plan milestones, and any Aperio custom properties. We configure department and job title records in BambooHR before employee import so that referential integrity is maintained. If BambooHR Performance is active, we document the Aperio review template structure for the admin to rebuild.
Goal hierarchy reconstruction from flattened CSV
We process the Aperio Goals CSV export to extract all goal_id and parent_goal_id pairs. We validate that each parent_goal_id reference resolves to a real goal record, flag orphaned child goals and circular references, and build a parent-child mapping table. We then structure the goal data for BambooHR custom fields on the Employee record, storing goal text, status, due date, and parent goal reference for each record. This step runs as a pre-load transform before any data is written to BambooHR.
Custom field value-set mapping and sign-off
We extract all picklist and multi-select values from Aperio custom fields, map them to BambooHR custom field value sets, and flag any values that have no direct equivalent in BambooHR. We present the discrepancy list to the customer for resolution: either the customer maps non-matching values to valid BambooHR options or accepts that those values will be stored as text with a note. This step requires customer input before loading and is a common source of timeline slip if deferred.
Sandbox migration and reconciliation
We run a full migration into the customer's BambooHR sandbox using production-like data volume. The customer's HR admin reconciles record counts (employees in, departments in, goals in), spot-checks 25-50 random records against the Aperio source, and validates custom field content. The admin also reviews the Aperio review template inventory and BambooHR Performance cycle design. Sign-off on the sandbox migration gates production migration.
Production migration and cutover
We freeze writes in Aperio during cutover, extract final CSV exports, run the full migration into production BambooHR, and validate record counts and sample data post-load. We deliver the review template and competency library inventory document to the customer's admin team for BambooHR Performance rebuild. We support a one-week hypercare window to resolve any data quality issues reported by the HR team. We do not configure BambooHR Performance review cycles or workflows as part of the migration scope; these require admin configuration post-migration.
