UCOP Cascade Help
While deleting, moving and renaming are all possible actions within Cascade, they should be performed with the utmost caution and only when necessary. These actions affect the structure of your live website and, if done improperly, can lead to broken links, confusing navigation and inaccurate content.
PLEASE NOTE: Most UCOP content editors do not have permission to publish or unpublish to or from the live website. If you do not have access to the production server, you should not delete, move or rename files , pages  or folders , for the reasons described above. Please contact the help team at email@example.com and ask them to perform these actions for you.
Remove assets from your site.
Move assets between folders within your site, and/or change their system names.
