You can reduce the size of a database by deleting versions no longer required. By reducing the size of a database, you can save storage space and increase access speed.
If you delete old versions, all current data is still available in the database. Current data means that all models available in the remaining versions and the Workspace versioning state and their contents still exist in the database.
The following graphics show what happens when you delete a version.
Assumed that a database contains four change lists.
The first two change lists must be deleted to reduce the database size and increase the access speed. For this reason, the third change list is selected and the corresponding delete functionality is executed.
The first two change lists are deleted. During the version deletion, the last visible versions of models are copied to the last previous change list that is not deleted. As a result, all relevant model data is preserved.
In the example, this applies to the Model 2 version. During the version deletion, this model was copied from change list 2 to change list 3.
