Upgradability

The Upgradability tab allows you to perform the following actions:

• View the upgrade paths from and to the selected version of the service design
• Navigate to those service designs
• Add an upgradability relationship between service designs
• Delete the upgrade path from a service design
• Edit the description about the differences between the selected version and a version to or from which it can be upgraded
• View the differences between the selected version and the version from or to which it can be upgraded

Certain functions are restricted on a design if it is part of an upgrade path. See Upgradability restrictions for more information.

Tasks

The following options are available from the Upgradability tab:

• <version number> — Click to display the selected version of the service design.
• Edit upgrade path description — Click the gear icon and select Edit to update the description about the differences between the versions of the design in an upgrade path.
• Delete upgrade path — Click the gear icon and select Delete to remove the upgrade path from the listed service design version. If an upgrade to an offering uses this upgrade path, (that is, the selected service design upgrade path is used to update the service design for an upgrade of an offering), the selected service design upgrade path cannot be deleted.
• Add upgrade path — Click Add to define the upgrade path that establishes an upgradability relationship between two different versions of a service design. In the Add Upgrade Path dialog, select an eligible service design in the From Version drop-down list. Enter a brief, meaningful description of the upgradability relationship between the selected version of the service design and another version of the same service design. This action will validate whether service design versions are upgradable to the current service design version. If service design versions are not upgradable, upgradability violations will be recorded in log files.
• Review differences between versions — Click View Differences to view the differences between the versions of the design in an upgrade path. In the Differences between version dialog, design components and subscriber options that have been added, updated, or removed are listed. Changes to design components are displayed on the left and changes to the subscriber options are displayed on the right. The differences are color-coded to easily identify the types of changes, where additions are blue, updates are yellow, and removals are red.
