What is the first step to ensure VMs are available for Azure Migrate when using a Hyper-V host?

The first step to ensure that virtual machines (VMs) are available for Azure Migrate when using a Hyper-V host is to add the Hyper-V host as a discovery source. This step is essential because Azure Migrate needs to identify the source environment to assess and migrate the VMs effectively. By adding the Hyper-V host as a discovery source in Azure Migrate, you establish connectivity and enable the Azure Migrate service to communicate with the Hyper-V infrastructure, discover the VMs, and gather necessary metadata about their configurations and usage.

Once the Hyper-V host is registered as a discovery source, Azure Migrate can start the process of inventorying the VMs and preparing them for migration. Other steps, such as configuring network settings, installing a new operating system, or setting up user permissions, may be part of broader planning and preparation efforts but do not directly initiate the process of making the VMs discoverable and assessable by Azure Migrate.
