HRIS Implementation & Migration Checklist
Get the step-by-step framework to go live on a new HR system without data loss, missed workflows, or adoption failures, whether you're implementing from scratch or migrating from an existing platform.
HR Toolkit
Why you should use this toolkit
An HRIS implementation touches every corner of your HR operation, from how employee data is stored and accessed, to how managers approve leave requests, to how new hires are onboarded. Unlike a payroll-only go-live, it requires aligning HR, IT, finance, and department managers across a longer timeline.
This checklist was built for HR teams managing that complexity. Whether you’re implementing an HRIS for the first time or migrating from a legacy HR system, it gives you a phase-by-phase sequence with clear ownership and exit criteria at every step — so nothing gets missed in the rush to go live.
HRIS implementation — common questions
Your questions, our answers.
What is the difference between an HRIS implementation and an HRIS migration?
Implementation means setting up an HRIS for the first time : building your org structure, configuring workflows, and loading employee data from scratch or from spreadsheets.
Migration means moving from one HR system to another: you still do everything an implementation requires, but you also need to export historical data from your legacy platform, clean and remap it to the new system’s schema, and manage a cutover plan that minimizes disruption.
Combien de temps prend l'implantation d'un SIRH?
For most SMBs (50–500 employees), an HRIS implementation takes 6 to 12 weeks from kickoff to go-live. Simple configurations with clean data can be completed in 4–8 weeks.
What data needs to be migrated when switching HR systems?
A full HRIS migration typically involves transferring:
- Employee master records (personal info, job titles, start dates, reporting lines)
- Organizational structure (departments, cost centers, locations)
- Leave balances and absence history
- Performance records, goals, and review history (if applicable)
- Documents and e-signatures (contracts, policies, onboarding files)
- Custom fields and HR workflow configurations
- Payroll-linked data (if your HRIS includes or connects to payroll)
Data quality issues — duplicate records, inconsistent job titles, missing fields — are the most common source of delays.
Who should be involved in an HRIS implementation project?
An HRIS rollout typically requires coordination across more stakeholders than a payroll-only project:
- HR team: owns configuration, data migration and training.
- IT: handles SSO, API integrations and data security.
- Finance/Payroll: validates payroll sync and cost center mapping.
- Department managers: key end users who need early onboarding and a voice in workflow design.
