    * **trustedRootCertificates: [PSApplicationGatewayTrustedRootCertificate]: Optional**. A comma-separated list of PSApplicationGatewayTrustedRootCertificate objects that you create to represent the [Trusted Root certificates](ssl-overview.md) for authentication of your backend instances from your v2 gateway.

    * **privateIpAddress: [String]: Optional**. A specific private IP address that you want to associate to your new v2 gateway.  This must be from the same VNet that you allocate for your new v2 gateway. If this isn't specified, the script allocates a private IP address for your v2 gateway.
-    * **publicIpResourceId: [String]: Optional**. The resourceId of a public IP address (standard SKU) resource in your subscription that you want to allocate to the new v2 gateway. If this isn't specified, the script allocates a new public IP in the same resource group. The name is the v2 gateway’s name with *-IP* appended.

If this isn't specified, the script allocates a new public IP in the same resource group. The name is the v2 gateway’s name with *-IP* appended.
    * **validateMigration: [switch]: Optional**. Use this parameter if you want the script to do some basic configuration comparison validations after the v2 gateway creation and the configuration copy. By default, no validation is done.
    * **enableAutoScale: [switch]: Optional**. Use this parameter if you want the script to enable AutoScaling on the new v2 gateway after it's created. By default, AutoScaling is disabled. You can always manually enable it later on the newly created v2 gateway.
