How long does it typically take to migrate payroll history when switching HRIS providers mid-year in APAC?

Omni HR assigns a dedicated Customer Success Manager to handle the full migration, including data auditing, payroll history transfer, and a parallel run to check payroll output before go-live. A mid-year switch usually takes longer than a start-of-year one, because year-to-date figures need to reconcile correctly for filings like BIR 2316, the EA Form, or IR8A. Running at least one payroll cycle in parallel before cutover is the standard way to confirm the new numbers match.
