UCOP Cascade Help
Applicable to: all assets | Skill level: intermediate
Goal: Remove unneeded assets.
You most likely do not have the ability to un-publish from the production server. So, deleting an asset, even though you un-publish from dev, will leave it on the production server with no way to then un-publish it, leading to multiple, possibly erroneous versions of the asset being online. Though you might not see the asset on your website, it will still be findable by a search engine or anyone who has bookmarked the old URL.
Assets you can delete
- blocks 
(but check Relationships to make sure the block isn't being used on other pages)
- references .
Assets you CANNOT delete
- pages 
- files 
- folders 
One exception: if you have not published the asset, you can safely delete it. If the asset has already been published, contact firstname.lastname@example.org to request that it be deleted.
If you need to delete a page, file or folder, contact email@example.com to request that it be deleted.
If you need to delete, a block or reference:
Navigate to the asset you would like to delete.
Click the Delete tab.
Submit the page to confirm the deletion.
If the asset you are deleting is linked from another page, you will see a warning that links may be broken. The name of the page that contains that link is shown. You'll need to modify that page to remove the link to the asset you are deleting.
