Older versions of a CDT - are they deleted when there are no references to them?

Hi All,

We know that a CDT when updated, a new version gets created. The older version still exists, only difference is that it has a different name(with ^ followed by a number).

Let's say that the older version is no longer referenced by any of the objects in the environment. No process model, rule or Data Store references it, and neither any process instance. Assume that all the process instances which were referencing the old version are archived/deleted.
So, there are zero references to it.

Does Appian automatically delete the Old CDT version from the environment if there are no longer any references to it? Or, does it still remain in the environment?
Is there some automatic cleanup of old CDT version that Appian does?

  • @kondetiv, the new version does not replace the old version. You can reference the old version even after the new version of CDT is created.
    The old version exists.
    My question is that - is it ever possible that the older version of the CDT be deleted permanently after some long duration - when the old version is no longer referenced anywhere
