Go-live is the culmination of months of planning, configuration, and testing. A well-executed cutover minimizes risk and sets the stage for successful adoption. This checklist covers everything you need to verify before, during, and after your NetSuite go-live in 2026—so nothing falls through the cracks.
Pre-Go-Live
Complete these items in the weeks leading up to go-live. Most should be finished at least one week before cutover.
Data Validation
- Customer and vendor records migrated and validated
- Item/inventory data loaded with correct costing and quantities
- Opening balance sheet (A/R, A/P, inventory, fixed assets) reconciled
- Historical transactions imported if required (e.g., prior-year data for reporting)
- Data migration runbooks documented and tested
User Acceptance Testing (UAT)
- All critical business processes tested end-to-end
- UAT sign-off obtained from process owners
- Defects logged and resolved or deferred with approval
- Integration testing completed for all connected systems
Training
- Role-based training completed for all end users
- Super users identified and trained for each department
- Job aids and quick reference guides distributed
- Training attendance and completion tracked
Cutover Plan
- Cutover timeline and milestones documented
- Freeze dates communicated (e.g., no new orders in legacy after X date)
- Rollback plan defined in case of critical issues
- Stakeholders and executive sponsors aligned on go/no-go criteria
Go-Live Day
Execute these steps on cutover day. Assign owners and schedule check-ins every few hours.
System Cutover
- Final data migration run executed
- Data validation checks passed (record counts, balance reconciliation)
- Integrations switched to production endpoints
- User access and roles verified
- Legacy system placed in read-only or decommissioned per plan
Monitoring
- War room or command center established with key team members
- System performance and error logs monitored
- Integration health checks running (e.g., order sync, payment status)
- Issue tracking tool (e.g., Jira, ServiceNow) ready for incident logging
Support Team
- Support team staffed and available during business hours
- Escalation path defined for critical issues
- Super users briefed and ready to assist colleagues
- Implementation partner on standby for technical support
Post-Go-Live
These activities extend through the first weeks and months after go-live to ensure stability and continuous improvement.
Hypercare
- Daily standups for the first 1–2 weeks to address issues quickly
- Issue triage and resolution tracked with target SLAs
- First period close completed successfully with finance sign-off
- Key reports and dashboards validated against legacy or expected results
Feedback and Optimization
- User feedback collected via surveys or focus groups
- Enhancement backlog prioritized for post-hypercare phases
- Performance baseline established and monitored (page load times, search performance)
- Knowledge base updated with lessons learned for future projects
Go-live is not the finish line—it's the start of a new chapter. A thorough checklist keeps risks in check, while hypercare and feedback loops ensure your NetSuite investment delivers lasting value.
