Allow changing the Service Principal associated with AKS
Currently it's impossible to change the Service Principal associated with Azure Kubernetes Service.
You might want to change the service principal if you're doing big changes in your Azure AD or moving your Azure Subscription to another directory.

When I tried to upgrade AKS in my newly moved account, It worked. However, the load balancer and storage connection failed because the SP wasn't moved to the new account. I tried to update the SP using the update-credentials command. That resulted in a cluster failure state. I was told by the support team that it is not possible to move AKS from one account to another account. I had to create a new cluster and move data.
