 The Azure Migrate appliance continuously collects information about on-premises machines, and an assessment is a point-in-time snapshot. If you change the settings on a VM that you want to assess, use the recalculate option to update the assessment with the latest changes.

+## How do I discover VMs in a multitenant environment?
 
 - **VMware**: If an environment is shared across tenants, and you don't want to discover a tenant's VMs in another tenant's subscription, create vCenter Server credentials that can access only the VMs you want to discover. Then, use those credentials when you start discovery in the Azure Migrate appliance.
 - **Hyper-v**: Discovery uses Hyper-V host credentials. If VMs share the same Hyper-V host, there's currently no way to separate the discovery.

 Yes, Azure Migrate needs vCenter Server to perform discovery in a VMware environment. It doesn't support discovery of ESXi hosts that aren't managed by vCenter Server.

 With as-on-premises sizing, Azure Migrate doesn't consider VM performance data for assessment. It assesses VM sizes based on the on-premises configuration. With performance-based sizing, sizing is based on utilization data.

 ## What do I install for agent-based dependency visualization?
 
-To use dependency visualization, you need to download and install agents on each on-premises machine that you want to evaluate.
+To use agent-based dependency visualization, you need to download and install agents on each on-premises machine that you want to evaluate.
 
 Install the following agents on each machine:
 - [Microsoft Monitoring Agent (MMA)](https://docs.microsoft.com/azure/log-analytics/log-analytics-agent-windows).
 - [Dependency agent](../azure-monitor/platform/agents-overview.md#dependency-agent).
 - If you have machines with no internet connectivity, you need to download and install Log Analytics gateway on them.

 ## Can I export the dependency visualization report?
 
-No, the dependency visualization can't be exported. However, Azure Migrate uses Service Map, and you can use the [Service Map REST API](https://docs.microsoft.com/rest/api/servicemap/machines/listconnections) to retrieve the dependencies in JSON format.

 ## Can I visualize dependencies for more than an hour?
-No. You can visualize dependencies for up to an hour. You can go back to a particular date in history, as far back as a month, but the maximum duration for visualization is an hour. For example, you can use the time duration in the dependency map to view dependencies for yesterday, but you can view dependencies for a one-hour window only. However, you can use Azure Monitor logs to [query dependency data](https://docs.microsoft.com/azure/migrate/how-to-create-group-machine-dependencies) over a longer duration.

 ## Can visualize dependencies for groups of more than 10 VMs?
 You can [visualize dependencies](https://docs.microsoft.com/azure/migrate/how-to-create-group-dependencies) for groups containing up to 10 VMs. If you have a group with more than 10 VMs, we recommend that you split the group into smaller groups, and then visualize the dependencies.
