Say I have an application labeled A & B.
I want to supersede A with B, and notify users that there is an update and for them to go into Software Center and upgrade.
1. What option provides the notification option? Is it after adding the supersede, that SCCM knows automatically?
2. Do I retire application A now that it is being superseded?
3. Do superseded applications still need to belong in the catalog for the supersede to work?
3a. for example now I have application A, B, and C. A is superseded by B, and now B is superseded by C. Should I be keeping A around so that people can jump to C?
