I have an App Service plan on which we have deployed some applications. For the needs of reorganizing server and applications I wanted to rename the service plan which was in a standard resource group "Default-Web-WestEurope-blablabla".
Given that an App service plan cannot be renamed I have during the time created another resource group and gradually moved all my apps and services (Storage, Database ,etc.) inside the new resource group. Also the old App Service plan has been moved to the new resource group.
The scope was to have everything inside a new resource group and then create a new App Service plan where to move all the app services in the previous one by using the "Change App Service plan feature".
However I have discovered, after having created a new App service plan, that when I try to hit the "Change App Service plan feature" option, the answer is "No App Service plan found"!
How can I move all the resource between the two App Service plan?
EDIT:
I have tried by using Powershell and I get a a reason.
