Go-Live: The Critical Transition
Go-live is the moment your organization switches from the legacy system to NetSuite. A well-planned cutover minimizes disruption; a poorly planned one can delay launch and frustrate users. This guide provides a playbook for planning, executing, and supporting the cutover.
Cutover Timeline Overview
Typical cutover: 1–3 days. Day -1: Final data migration, validation. Day 0: Freeze legacy, last extract, load, final validation, flip users to NetSuite. Day +1: Hypercare, issue resolution. Extend for complex migrations.
| Day | Activities |
|---|---|
| Day -1 | Final extraction, transformation, load; validation runs |
| Day 0 | Freeze legacy; last load; final validation; user flip; smoke tests |
| Day +1 to +7 | Hypercare; daily stand-up; issue triage; quick fixes |
Freeze Period
Define when legacy system data entry stops. Communicate to all users. Plan for a weekend or low-activity period. Ensure all open transactions are migrated or documented. Consider partial freeze (e.g., AR frozen, but inventory receives continue) for phased approaches.
Data Migration Sequence
1) Master data (accounts, entities, items), 2) Opening balances, 3) Open transactions (bills, invoices, POs, SOs), 4) Historical (if applicable). Run validation after each phase. Have rollback scripts ready.
Validation Checklist
Record counts match. Key totals reconcile (AR aging, AP aging, inventory). Critical reports produce expected results. User acceptance test (UAT) sign-off. Document all validation results for audit.
Rollback Plan
Define criteria for rollback (e.g., critical data error, system unavailable). Have a decision maker. Keep legacy system available for 1–2 weeks. Document steps to revert and communicate to leadership.
Post-Launch: First Week
Hypercare: dedicated support team, extended hours. Daily stand-up to triage issues. Quick-fix prioritization. User feedback collection. Document all issues for post-launch backlog.
Communication
Notify users of freeze dates, go-live timing, training, and support channels. Provide quick reference guides. Set up a support mailbox or portal. Executive sponsorship helps manage expectations.
