Challenge
The environment contained several interdependent Azure services that had historically supported remote working, authentication, application hosting, and office connectivity. Key challenges included safely removing Azure Domain Controllers, migrating from hybrid identity to cloud-only Microsoft Entra ID, retiring Azure Virtual Desktop infrastructure, removing Azure Firewall and VPN dependencies, reconfiguring office DNS and networking, and maintaining continuity for printing and endpoint management services.
Approach
A phased decommissioning strategy was implemented to minimise operational risk and maintain business continuity. The project included validation of Azure Backup recovery points, controlled shutdown of Azure Virtual Desktop host pools and legacy servers, migration from Microsoft Entra Connect synchronisation to cloud-only identities, DNS and DHCP reconfiguration on the Head Office WatchGuard firewall, migration of UniFi infrastructure to Sharp’s managed controller platform, replacement of Universal Print with Intune-managed local printer deployment, and removal of Azure Virtual Machines, networking resources, disks, VPN components, and firewall services.
Outcome
The project successfully delivered a simplified Azure environment with reduced infrastructure complexity, lower operational overhead, and improved long-term scalability. Legacy Azure-hosted infrastructure was removed, Microsoft Entra ID became the primary cloud-native identity model, Azure Firewall and VPN infrastructure were retired, endpoint and printer management were simplified through Intune, and Azure operational costs were significantly reduced while retaining backup protection for rollback and compliance purposes.
