upgrading from 2015 to 2017

Hey!

I have Adobe CC 2015 installed on a device enterprise license. All the AUSST server I have seems to do is to update the apps to the latest 2015 version.

I want to upgrade them all (150) to 2017 version.  However, the guides just mention using the creative cloud app to update the apps.

Enterprise deployments on device licenses cannot be updated using the Creative Cloud App.

The only thing I can think of is to create a new package using CCP and deploy again over the old 2015 installation.   Will it upgrade the old one?

Thanks for your help.
