Intune Update Scenario
To upgrade a LOB App in intune, just replace the msi with a newer version.
No need to make groups for different versions as Intune only supports upgrading, not downgrading.
The only reason to publish different versions would be for a pilot group or for users that require a spesific version.

Hey thanks for your fast reply.
So in my case it isnt a MSI we use a Powershell-Wrapper, that is packed into a intunewin-file. With that way, downgrading should be still possible I guess?
So if I replace the MSI (or in my case the intunewin-file) intune will start a (re)installation on every client, even though it is already installed on that client with a different version? Or does intune still compares the detection rule if the app is already installed?
I belive you have to update your detection rule to something version spesific to trigger a new install as the detection rule is one of the first actions that's triggered during Win32 deployment.
You can try adetection rule with type File with detection method String(version)

https://modernworkplace.fremmegaard.noOkay thats also an interesting point; My Wrapper writes a Branding with the Softwareversion into the registry. Actually I only check, if the Branding exists, but due to your information I will compare the Version-Key.
What still dont me make happy is that intune doesnt removes the old version. If you have a MSI this will probably be no problem as it checks the Upgradecode. But if you have an EXE-File, then you could get trouble when the software doesnt detects, that theres already a preversion installed - which could end in having two different Versions on that client. Still trying to find a solution for that...
If I choose the way, to create an app for each version, then I could assign the uninstallation of the preversion to the current version. But is there a chance to create a installation order? So that first of all the uninstallation assignment will be executed and then after it the installation?
