 - If you don't want to use a template, you can deploy the appliance for VMware or Hyper-V environment using a [PowerShell installer script](deploy-appliance-script.md).
 - In Azure Government, you should deploy the appliance using a PowerShell installer script. Refer to the steps of deployment [here](deploy-appliance-script-government.md).
 - For physical or virtualized servers on-premises or any other cloud, you always deploy the appliance using a PowerShell installer script. Refer to the steps of deployment [here](how-to-set-up-appliance-physical.md).

     > [!Note]
     > - Don't install any other components, such as the **Microsoft Monitoring Agent (MMA)** or **Replication appliance**, on the same server hosting the Azure Migrate appliance. If you install the MMA agent, you can face problems like **"Multiple custom attributes of the same type found"**. It's recommended to have a dedicated server to deploy the appliance.

+## Verify security
+
+Before you use the OVA/VHD/Zip file to deploy appliance, verify that the file is secure:
+
+1. On the server where you downloaded the file, open Command Prompt window by using **Run as administrator** option.
+1. Run this command to create the hash for the OVA/VHD/Zip file:
+
+Copy 
+
+`C:\>CertUtil -HashFile <file_location> <hashing_algorithm>` 
+
+For example: 
+
+Copy 
+
+`C:\>CertUtil -HashFile C:\Users\Administrator\Desktop\MicrosoftAzureMigration.ova SHA256` 
+
+`C:\>CertUtil -HashFile C:\Users\Administrator\Desktop\MicrosoftAzureMigration.ova SHA256`
+
+`C:\>CertUtil -HashFile C:\Users\administrator\Desktop\AzureMigrateInstaller.zip SHA256`
+
+1. Verify the latest appliance versions and hash values: 
+    1. Use the OVA file to set up the VMware appliance in Azure public cloud.
