Case Study: Johnson Matthey Plc achieves single AD consolidation (27 forests → 1 in 8 months) with Quest Migration Manager and Active Roles

Johnson Matthey accelerates AD consolidation

Johnson Matthey, a FTSE‑100 specialty chemicals and precious metals company with about 10,000 employees across 30+ countries, needed to replace a devolved IT model of 27 Active Directory forests with a single, centrally managed AD. The project had a tight deadline and also had to preserve local admin delegation and provide full auditing to meet security and compliance requirements.

The company implemented Quest Migration Manager for Active Directory alongside One Identity Active Roles for delegated management and Change Auditor for auditing. The consolidation was completed in eight months with no data loss, using rollback when needed; it cut the migration timeline by 83% (from an estimated four years), reduced local admin support calls by 98%, and improved security and regulatory compliance.
