In-Depth Information
Application management in Configuration Manager enables you to upgrade or replace exist-
ing applications by using a supersedence relationship. When you supersede an application,
you can specify a new deployment type to replace that of the superseded application. In
addition, you can configure whether to uninstall the superseded application.
When you supersede an application, the supersedence applies to all future deployments
and Application Catalog requests. The effect on existing deployments depends on the
options that you choose. To leave the superseded application in place, you can choose Do
Not Replace, or you can specify a new deployment type to replace the old deployment type.
If the superseded application has multiple deployment types, you specify a new deployment
type for each old deployment type that you want to replace. Whether you choose a new
deployment type or not, you can uninstall the application by selecting the Uninstall check box
for each old deployment type. Supersedence options are as follows:
■
You configure the supersedence to uninstall the old deployment type, and you deploy
the application with the required action. When you do this, the existing application is
uninstalled, and the new application is installed.
■
You specify a new deployment type and do not configure the supersedence to unin-
stall the old deployment type. If successful, the existing application will not be unin-
stalled, and the new application will perform an in-place upgrade of the old
application where possible. If not successful (for example, replacing a software title
with a competitor's product), the old application is not removed from the target, and
the new application is installed.
You can view the supersedence and dependency relationships between applications, as
shown in Figure 2-10, in a variety of ways:
In the application's Properties dialog box of the superseding application, on the
Supersedence tab, you can view the applications this application supersedes.
■
In the application's Properties dialog box of the superseded application, on the
References tab, you can use these options: Applications That Depend On This
Application and Applications That Supersede This Application.
■
With a superseding application selected, on the ribbon, you can click View
Relationships to view dependencies, supersedence, and global conditions related to
the selected application.
