Hi stianen,
do you mean you want to upgrade the visual Studio and migrate your project from one version to another version of Visual Studio?
generally when you open the project in new version of Visual Studio then it will show a prompt for it.
it can be one way or two way upgrade.
if you do it then then project will be converted to the version which is supported by the newer version of Visual studio.
at this time you not need to type any command.

let me know, if I misunderstand anything in your above description.
I will try to correct myself and try to provide you further suggestions.
if it is some kind of Feature request then you can post your suggestion on Visual Studio user voice and close this thread.
