Allow azure function migration to new plan for linux OS

Hi,

I currently have an azure function that is using a consumption plan. I wanted to upgrade to premium, so I started with creating a premium App Service Plan.
Next I wanted to update my Azure function using the CLI as follows

`az functionapp update --name my-azure-function --resource-group myresourcegroup --plan my-premium-plan-test`

However this is only supported for Windows machines it seems, as I am getting the following error:
`ValidationError: This feature currently supports windows to windows plan migrations. For other migrations, please redeploy.`

Would it be possible to allow functionapp migrations for linux OS ? Thanks.
