In a rapidly evolving digital landscape, businesses using legacy IT Service Management (ITSM) systems often struggle with slow workflows, maintenance burdens, and limited scalability. Migrating to ServiceNow ITSM offers an opportunity not only to modernize but to streamline, automate, and enhance user experience across the board. This guide walks you through the best practices, steps, and considerations to make that move smooth and successful.
1. Why It's Time to Move from Legacy ITSM
Legacy tools tend to create technical debt - outdated customizations, duplicated work, and performance bottlenecks.
Time to market slows down, user dissatisfaction grows, and operational costs increase significantly.
Modern platforms like ServiceNow provide cloud‑based agility, integrated workflows, dashboards, and better maintenance.
2. Key Risks & Challenges to Plan For
Data migration: historical ticket data, custom fields, help‑desk workflows may not map directly.
Customizations: too many custom features can make upgrades difficult and costly.
Stakeholder resistance: change is difficult; needs strong communication & training.
Downtime & service continuity: ensure critical services are not disrupted during migration.
