About This Architecture

Azure VM DNS to Azure Private DNS Zone migration architecture showing a seven-step transition from self-managed DNS servers to Azure's managed DNS service. The current state features a Standard_D2s_v3 VM hosting DNS with NSG, Public IP, and monitoring via Azure Monitor and Key Vault, while the target state consolidates DNS resolution through Azure Private DNS Zone (contoso.internal) and Azure Public DNS Zone (contoso.com) linked to application VNets. Migration steps include exporting zone files, creating private DNS zones, importing records, updating VNet DNS settings, validating resolution, and decommissioning the legacy VM. This pattern eliminates operational overhead, improves availability, and aligns with Azure best practices for hybrid and cloud-native workloads including App VMs, AKS Clusters, and Application Gateways.

How do I migrate DNS from an Azure VM to Azure Private DNS Zones?

This diagram shows a 7-step migration process: export DNS records from your current VM, create an Azure Private DNS Zone, import records, update VNet DNS settings to point to the managed zone, validate resolution across workloads, then decommission the legacy VM and remove associated resources. Azure Private DNS Zones provide managed, highly available DNS without operational overhead.
