NWDI upgrade - Target Release Components

Hello everybody!

Currently, we are trying to upgrade our NWDI from 7.0 to 7.31. During the upgrade process of the server that contains DTR, CMS and CBS, in step 5.3 "Configuration - Information Gathering" we get a list of Java components (Target Release Components) with some additional information and the option to either remove these components or to "scan inbox" for component versions for NetWeaver 7.31.

In this list, there are some components with a component name that matches the application name of some (not all) applications we developed (like anlUsrWD in the heavily edited and shortened screenshot below):

My question is: What exactly do these items (those that match some of our self-developed applications) in this list represent ? Are they essential for CBS, CMS or DTR ?

A long time ago, this server was used as a test portal server. Maybe these are leftovers from past deployments that can be deleted, but maybe they are needed on this server and our build and deploy processes will no longer work without them, maybe even DTR will no longer work. We are in no way sure of what we have to do with them.

Can anyone help ?
