Summary:
The documentation demonstrates a Windows bias by providing extensive PowerShell-based instructions and automation, referencing Windows-specific tools and modules, and omitting Linux-specific guidance. PowerShell is featured heavily, including for automation and module installation, with no mention of Bash scripting, Cloud Shell, or Linux-native automation. Prerequisites and upgrade steps reference PowerShell and its modules exclusively. While Azure CLI examples are present, there are no Linux shell or cross-platform scripting examples, and PowerShell is often mentioned first or exclusively for advanced scenarios.
Recommendations:
- Provide equivalent Bash or shell script automation for migration tasks, especially for Virtual Machine Scale Set automation.
- Reference Azure CLI and cross-platform tools first or alongside PowerShell in all sections, including prerequisites and automation.
- Include instructions for installing and using Azure CLI and relevant extensions on Linux/macOS.
- Offer guidance for Linux users on how to perform module-based automation, or clarify if certain modules are Windows-only.
- Mention and demonstrate use of Azure Cloud Shell, which supports both Bash and PowerShell, to encourage platform-neutral approaches.
- Ensure that all advanced automation steps have CLI or REST API equivalents, and document them.
