You can compare a snapshot or workspace with a previous
version, and you can compare up to three snapshots and workspaces
that have the same base snapshot. For example, at the end of a project
milestone, you might compare a previous snapshot with the existing
workspace.
Before you begin
- You should be familiar with project
areas, configuration spaces, snapshots, workspaces,
and change sets, which are described in Management of shared resources.
- You must be logged in to a project,
and you must be in a workspace that is associated with the current
configuration space.
About this task

contain different resources (identified by the URI or the name of
a resource), or different versions of the same resources. You cannot
compare the actual contents of the resources.
Procedure
- Open the Configuration Explorer view.
On the toolbar of a lifecycle management product, click .
- Complete one of the following steps:

Description |
| Compare a configuration with the previous version |
In the Actions column beside a configuration
name, click the Compare with Previous icon.
The previous version of a configuration varies depending on the type
of configuration that you select:- If you select a workspace, the versions of resources in the workspace
are compared with the versions of resources in the base snapshot of
that workspace.
Tip: In the Configuration Editor, on the Overview tab
for the selected workspace, see the value in the Base snapshot field.
- If you select a snapshot, the versions of resources in the selected
snapshot are compared to the contents of the snapshot whose Time Order
dimension most closely precedes that of the selected snapshot.
Tip: In the Configuration Editor, on the Dimensions tab
for the selected snapshot, see the value of the Timer Order dimension.
