Deleting Lifecycle Models

You can delete an existing lifecycle model by using the Lifecycle Models page. You can access this page only if you have the Manage Lifecycle Models permission for a particular organization in CentraSite.

To delete a lifecycle model, you must first deactivate the lifecycle model. This means that you should change the lifecycle model's own lifecycle status from Productive to Retired.

If several versions of the lifecycle model exist, CentraSite offers two commands for deleting versions, namely Delete and Purge. The Delete command deletes the newest version of the lifecycle model; if you use the Delete command on an older version, the command is rejected. The Purge command deletes the requested version and all other versions that are older than the requested version.

Command	Description
Delete	Deletes the newest version of a lifecycle model. This command cannot be used on an older version of the lifecycle model.
Purge	Deletes the selected version and all older versions of a lifecycle model. If the selected version is the newest version, this command removes the lifecycle model altogether from CentraSite.

When you purge old versions of a lifecycle model, any existing newer versions does not be deleted. In this case, assets governed by this lifecycle model continues to be governed by this lifecycle model.

If you have several versions of a lifecycle model and one of the older versions is still in the Productive state, you cannot purge any newer version, since this would automatically try to delete the older version that is in Productive state. This can happen, for example, if you have just created a new version of a lifecycle model but have not yet set the new version to the Productive state.

If you purge the newest version of a lifecycle model, you automatically delete all of the older versions also, that is, you remove the lifecycle model altogether from CentraSite. In this case, all assets that were governed by the lifecycle model are now of course no longer governed by the lifecycle model. You do not need to adapt these assets in any way for non-lifecycle usage and they are treated by CentraSite as if they had never been governed by a lifecycle model. The only visible change is that when you display the detail view of such an asset, the lifecycle status of the asset is no longer displayed.

Note: The lifecycle model for lifecycles and the lifecycle model for policies cannot be deleted. Also, if several versions of such a lifecycle model exist, none of the versions can be purged.

Important: If you have selected several lifecycle models where one or more of them are predefined models, you can use Delete to delete them. However, as you are not allowed to delete predefined lifecycle models, only models you have permission for is deleted. The same applies to any other lifecycle models for which you do not have the required permission.
