dotCMS keeps old versions of assets and content. All of this data takes up space and in some cases might impact performance. dotCMS does now periodically delete old non-active Elastic Search indexes.
The “Drop Old Asset Versions” operation allows you to delete all assets older than a certain date. This operation doesn’t delete any live or working content.
The Drop Old Asset Versions operation is located under System -> Maintenance -> Tools
Clean options are also available for the server File System.
