Data Flow — Hop 1 (Commvault) ​

=== "Nutanix AHV"

1. Commvault discovers Nutanix workloads through the supported Nutanix integration path for your release.
2. Protection jobs create the required protected copy on Commvault-managed storage.
3. For cutover, Commvault restores the protected VM to Hyper-V staging as a VHDX-backed VM.
4. Post-restore network settings, DNS, and workload validation occur on the Hyper-V staging host.

=== "Nutanix ESXi"

1. Commvault connects through the VMware integration path for ESXi-on-Nutanix sources.
2. Protection or copy jobs create the restore point on Commvault-managed storage.
3. Restored workloads are written to Hyper-V staging as VHDX-backed VMs.
4. The staging host becomes the Azure Migrate source for Hop 2.

Data Flow — Hop 2 (Azure Migrate) ​

Same as the other two-hop paths:

  1. Azure Migrate appliance discovers the staged Hyper-V VMs
  2. Replicates VHDX disks to Azure Local CSV storage
  3. Performs test migration and production cutover to create Azure Local VMs
