Upgrading AKS to 1.9


I have been following an AKS issue on GitHub - https://github.com/Azure/AKS/issues/103, where users appear to be able to upgrade AKS to 1.9.1 via the CLI.

Regardless of which method I use I cannot force an upgrade on my AKS cluster and it is not yet possible to create a 1.9 cluster from scratch.

This is the command I am using:

 az aks upgrade --name $ClusterName --resource-group $ResourceGroup --kubernetes-version $Version --yes

Each time I run this I receive the following message:

Operation failed with status: 'Bad Request'. Details: The selected orchestrator version is not supported

Now I am aware that 1.9 is not officially supported, but it seems to be possible based on the issue raised on GitHub.

Am I missing something?
