feat: script refinement — Hyper-V standalone conversion path

[kristopherjturner]

Overview

Refine and harden the standalone Hyper-V conversion path scripts (scripts/hyperv/) for converting Gen1 VMs on Hyper-V hosts that are not yet enrolled in Azure Arc. This path is used pre-migration to Azure Local.

Scope

• Hyper-V host compatibility check (Hyper-V version, VM hardware version)
• MBR → GPT disk conversion on Hyper-V VMs without Arc dependency
• Gen1 → Gen2 firmware conversion via Hyper-V PowerShell cmdlets
• Post-conversion validation: boot success, network connectivity, application health
• Batch conversion support: process multiple VMs from a CSV inventory file
• Consistent parameter sets and logging with the Azure Local path scripts

Acceptance Criteria

• Hyper-V path works on Windows Server 2019 and 2022 Hyper-V hosts
• Batch conversion handles VM inventory from CSV input
• Pre-flight catches unsupported OS versions and disk configurations
• Post-conversion validation confirms boot and network health
• Script parameter contracts consistent with Azure Local path

Dependencies

• Parent Epic: [Epic] VM Conversion Toolkit Full Build-Out #5
• Azure Local path scripts: feat: script refinement — Azure Local conversion path (01–05 scripts) #6
