Industry: Healthcare services (approx. 800 employees, multi-site)
Platform: Cloud HRIS (migration from legacy system and spreadsheets)
Engagement model: Data engineer and HRIS analyst, 4 months.
Moving from a legacy HR system, spreadsheets, and a separate payroll file to a modern cloud HRIS.
Employee records were duplicated, job and position data was inconsistent, and nobody was sure which source was correct.
A previous migration attempt had been paused over data-quality concerns.
Profiled data across all sources and produced a clear list of duplicates, gaps, and conflicts. Defined cleansing rules with HR and payroll owners so every decision had a named business approver.
Built repeatable load scripts and reconciliation reports instead of one-off manual fixes.
Ran 3 mock migrations, each with a before-and-after reconciliation.
Supported cutover weekend and the first payroll cycle after go-live.
Employee records corrected or merged before load
Final cutover reconciled against the approved source
Reusable data-quality reports kept in place for ongoing HR use
Data engineering skills for the migration
HR process knowledge alongside technical expertise
A data engineer and HRIS analyst working together
A small, senior team with both data engineering and HR process skills—the combination most migrations lack.
