Cannot update Azure Deployment when it is using Reserved IPs - azure

Question

I’m trying to install a diagnostic extension via API into an existing Azure cloud service. Cloud Service has a reserved IP assigned. I’m getting “A reserved IP cannot be added, removed or changed during deployment update or upgrade.” when doing so using ChangeConfigurationBySlot. Does anyone know the trick to get this to work? Is this a miss in the API or am I doing something wrong?
Here’s a relevant code snippet:
var dep = client.Deployments.GetBySlot(resource.ServiceName, DeploymentSlot.Production);
var serviceConfig = XElement.Parse(dep.Configuration, LoadOptions.SetBaseUri);
var config = new DeploymentChangeConfigurationParameters(serviceConfig.ToString())
{
ExtendedProperties = dep.ExtendedProperties,
Mode = DeploymentChangeConfigurationMode.Auto,
TreatWarningsAsError = false,
Configuration = serviceConfig.ToString(),
ExtensionConfiguration = new ExtensionConfiguration
{
AllRoles = new List<ExtensionConfiguration.Extension>(),
NamedRoles = extensionConfig
}
};
var result = client.Deployments.ChangeConfigurationBySlot(resource.ServiceName, DeploymentSlot.Production, config);
Here is the relevant section from cloud service config
<ServiceConfiguration xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" serviceName="IS.Admin.Azure" osFamily="4" osVersion="*" schemaVersion="2014-06.2.4" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceConfiguration">
<Role name="IS.Admin">
…
</Role>
<NetworkConfiguration>
<VirtualNetworkSite name="is-prod" />
<AddressAssignments>
<InstanceAddress roleName="IS.Admin">
<Subnets>
<Subnet name="Subnet-1" />
</Subnets>
</InstanceAddress>
<ReservedIPs>
<ReservedIP name="is-admin-rip" />
</ReservedIPs>
</AddressAssignments>
</NetworkConfiguration>
</ServiceConfiguration>
My update has nothing to do with changing/removing/adding Reserved IPs. Any ideas as to how to update the service config?

Try deploying to staging and doing a vip swap. The reserved ips are sticky to the slot, so it shouldn't interfere with your IPs in prod.
