Summary
The documentation demonstrates a moderate Windows bias: Windows examples and tools are often presented first, with more detailed step-by-step instructions and screenshots for Windows (e.g., WMI Control Panel configuration), while Linux instructions are more concise and sometimes lack equivalent detail or visual aids. Windows-specific tools and patterns (WMI, WinRM, Windows authentication, SQL Server) receive more attention, and some sections (like database discovery) focus almost exclusively on Windows technologies, with Linux or open-source alternatives only briefly mentioned or omitted.
Recommendations
  • Ensure Linux instructions are as detailed as Windows ones, including step-by-step guides, command-line examples, and screenshots where appropriate.
  • Present Linux and Windows examples in parallel or alternate their order to avoid always listing Windows first.
  • Include Linux-native tools and authentication methods (e.g., SSH, Linux-based SQL authentication) with equal prominence.
  • Expand database discovery sections to cover common Linux database scenarios (e.g., PostgreSQL, MariaDB) with least-privilege setup instructions.
  • Where Windows-specific tools (like WMI or WinRM) are discussed, provide Linux equivalents (e.g., SSH, systemd, or other monitoring tools) and explain how to configure them for Azure Migrate.
  • Add troubleshooting and permission validation steps for Linux environments similar to those provided for Windows.
  • Review all tables and code blocks to ensure Linux and Windows examples are equally represented and easy to follow.
