Hi,

I'm having issue with a function app where we're unable to see the function after the deployment. This function app is currently on a premium plan. I'm in the process of troubleshooting the problem and consider downgrading Function App A, which is currently on the sctask premium plan that includes features such as VNet that is not available under the dynamic plan. If I were to downgrade App A to a dynamic plan,

  1. Would I lose those features and settings still there after I moved to dynamic plan or they are still there but I won't have access to them?
  2. If I were to move back to the original premium plan or equivalent, do those features and settings revert to original configurations or do I have to configure everything again?

Note: Other function app under the Dynamic Plan seems to be working OK.

thanks and regards

DT

    Hi @DavidTra-1199,

    To answer your first question, yes you would lose those VNet integration capabilities. However, your VNET and subnet resources will not be removed.

    Addressing your second question, when you scale back up, you will need reconfigure the VNet integration with your function app. They don't revert to how it was previously configured. Meaning, if you had your function app configured to an app subnet, you will need set that configuration back up.

    To better understand why this is the case, when changing plans, your resources can get provisioned to different scale units. So, networking routing, more often than not, gets changed. If you want to have a repeatable provisioned environment, you can always use the Export template blade on the resource to create an ARM template.
