How to Migrate from BambooHR to an All-in-One Work OS
BambooHR is a well-liked HR system for growing companies. Consolidating it into a work OS connects the people record to the work those people do, which HR systems keep separate.
BambooHR earned its reputation by making HR approachable for small and mid-sized companies. Employee records, time-off tracking, onboarding workflows, and reporting are handled cleanly, and its friendliness drives the adoption that HR software often struggles to achieve. It is a good product doing a specific job well.
The case for consolidating is connection. In a dedicated HR system, the employee record sits apart from the work the employee does, the projects they staff, the tasks they own, the time they log against clients. Bridging that gap means integrations or manual reconciliation. A unified work OS keeps the same person as one identity across HR and delivery, so staffing, capacity, and time tracking share a model with the people record.
Handle HR data with extra care
HR data is sensitive and often regulated, so an HR migration carries obligations most tool migrations do not. Plan for privacy and access from the start.
- Personal data such as addresses, identifiers, and compensation, which needs strict access control.
- Employment records and history, which must be preserved accurately for compliance.
- Time-off balances and policies, which must migrate without corrupting accruals.
- Onboarding and offboarding workflows, which you will rebuild in the destination.
Export employee records precisely
BambooHR supports data export, including employee records and reports, in spreadsheet formats and offers API access for fuller extraction. Because accuracy and completeness matter more here than anywhere else, reconcile the exported record count and key fields against the source before importing, and export a dated snapshot you can audit against.
Map fields carefully, preserving employment dates, manager relationships, and time-off balances. Set up the destination's permissions before importing so sensitive data is never briefly exposed to the wrong people. Migrate a small pilot group, verify their records and access, then proceed with the full population.
Sequence the cutover around payroll and compliance
HR migrations have a constraint most tool switches do not: the calendar is not entirely yours. Payroll runs, benefits enrollment windows, and compliance reporting deadlines all impose fixed dates, and a migration that lands in the middle of one creates real risk to people's pay and records. Plan the cutover for a quiet point in the HR cycle, typically just after a payroll run and away from open-enrollment periods, and confirm the timing with whoever owns payroll before committing.
Keep the source HR system authoritative until at least one full cycle has run cleanly in the new tool. Because HR errors affect compensation and legal standing, the verification bar is higher than for a project tool: reconcile balances, confirm manager relationships, and check that access controls hide sensitive fields from the wrong people before you rely on the new system for anything official.
Connect people to the work they do
The value of consolidating HR is that the person record stops being an island. In a unified work OS, the same employee is the assignee on tasks, the resource on projects, and the person logging time, so capacity planning and utilization draw on one model rather than a reconciliation between HR and delivery tools.
Atlas includes HR alongside projects, tasks, time tracking, and analytics on one data model. The employee record connects directly to the work, so staffing and time reporting are native rather than integrated.
