HRMS Data Migration: What Moves, and How
Published: 24 Sept 2026 · Updated: 24 Sep 2026 · Author: NeevHR team
Migration decides how quickly a new HRMS becomes trustworthy. This guide lists what data to bring across, what NeevHR imports, and the workflow that gets you from spreadsheets to a reconciled first payroll.
What data moves into NeevHR
Month-by-month historical payslips are not imported. Keep them in your previous system or an archive for reference.
| Data | How it is handled |
|---|---|
| Employee master | CSV import with dry-run validation of every row |
| Organisation structure | Entities, locations, departments, grades and cost centres as masters |
| Salary structure | Pay structures configured, then assigned to employees with effective dates |
| Attendance | Attendance history import where needed; live punches from devices after go-live |
| Leave balances | Opening balances imported per leave type |
| Documents | Employee documents uploaded against the record |
| Payroll history | Year-to-date opening balances (gross, TDS, PF, ESI) so the current year computes correctly |
| Loans | Outstanding loan balances and remaining EMIs |
| Statutory information | PAN, UAN, ESI number and bank details, encrypted at field level |
| Pending arrears | Arrears owed from before go-live imported for payment |
The migration workflow
- 1
Data assessment
List every source (spreadsheets, old HRMS, payroll bureau) and decide what is needed in the new system.
- 2
Mapping
Map source fields to NeevHR fields and masters, and decide how to handle gaps.
- 3
Validation
Run each import as a dry run; every error is reported by row before anything is saved.
- 4
Dry run
Load a full data set into a test setup and compute a payroll month.
- 5
Reconciliation
Compare employee by employee against your current payroll and fix the causes of differences.
- 6
Parallel payroll
Run a live month in both systems and reconcile again.
- 7
Go live
Pay from NeevHR and retire the old process.
Practical tips
- Fix duplicate employee IDs, missing joining dates and inconsistent department names before import.
- Confirm each employee's work location, because PT and LWF depend on it.
- Take year-to-date figures from the last closed payroll month.
- Freeze master changes in the old system during the final import window.
