Summary:
The documentation page exhibits a strong Windows bias, as expected for Hyper-V scenarios, but with several areas where Linux parity is lacking or Linux is treated as an afterthought. Windows tools and patterns (e.g., PowerShell remoting, WinRM, WMI) are mentioned first and in detail, with Linux alternatives (SSH, Linux commands) often appearing later or with less detail. SQL Server and web app discovery are either unsupported or only partially supported for Linux. Example scripts and detailed instructions are provided only for Windows authentication and SQL Server, with no equivalent Linux database or web server examples. Some features (e.g., SQL Server instance discovery, ASP.NET web apps) are not supported for Linux at all.
Recommendations:
- Where possible, provide Linux-first or at least Linux-equal examples and instructions, especially for discovery, permissions, and connectivity (e.g., sample SSH configuration, Linux user setup).
- Explicitly state limitations for Linux support up front and provide guidance or workarounds if available.
- For SQL Server and web app discovery, clarify Linux support status and, if unsupported, suggest alternative approaches or roadmap.
- Include Linux command-line examples and configuration steps alongside PowerShell/Windows instructions (e.g., for enabling required ports, setting up user permissions).
- Ensure that all tables and requirement lists mention Linux and Windows in parallel, not just as an afterthought.
- If a feature is Windows-only, explain why and provide links to relevant Linux migration/assessment tools if possible.
