Summary:
The documentation demonstrates a Windows bias in its operational guidance for managing replication. All command-line examples (e.g., for throttling replication) use PowerShell cmdlets (New-NetQosPolicy), and configuration file paths are given in Windows format (C:\ProgramData\...). There is no mention of Linux equivalents or how to perform these tasks on a Linux-based Azure Migrate appliance. The documentation assumes the appliance and administrative environment are Windows-based, with no Linux parity in examples or instructions.
Recommendations:
- Provide equivalent Linux command-line examples (e.g., using tc or other Linux network QoS tools for bandwidth throttling).
- Document the location and format of configuration files on Linux appliances, if supported.
- Clarify whether the Azure Migrate appliance can run on Linux, and if so, provide Linux-specific operational guidance.
- When giving file paths or service names, include both Windows and Linux variants where applicable.
- Add a section or note explicitly addressing Linux support and any differences in management or configuration.

> This is applicable to all the replicating VMs from the Azure Migrate appliance simultaneously.
You can also increase and decrease replication bandwidth based on a schedule using the [sample script](common-questions-server-migration.md).
### Blackout window
Azure Migrate provides a configuration-based mechanism through which customers can specify the time interval during which they don't want any replications to proceed. This time interval is called the blackout window. The need for a blackout window can arise in multiple scenarios such as when the source environment is resource constrained or when customers want replication to go through only during non-business hours, etc.
> [!NOTE]
> - The existing replication cycles at the start of the blackout window will complete before the replication pauses.
> - For any migration initiated during the blackout window, the final replication won't run, causing the migration to fail.
A blackout window can be specified for the appliance by creating/updating the file GatewayDataWorker.json in C:\ProgramData\Microsoft Azure\Config. A typical file would be of the form:
