You can create, set, and rollback managed CI versions directly from the CI window. When you display the CI window for a managed CI, there are three actions in the Actions list that correspond to version control:
Add Future Version – displays the CI Version window so that you can create a Future version of the CI.
Rollback Version – rolls back the version of the CI. The Current version becomes the Future version, and the latest Previous version becomes the Current version. Each time you click Rollback Version, the CI rolls back through the list of Previous versions, and the CI window updates accordingly.
Set Current Version – displays the Set Current Version dialog, which displays a list of the Future versions for the CI. Only those Future versions that are not associated with a Change are listed. Click the row that corresponds to the version that you want to make the Current version.
The list on the Set Current Version dialog is based on the default query for the Version object for the CI.
