Soft Delete is the default deletion method, and can be done from either the Sites tool in the Administration Workspace, or the Worksite Setup tool for users with deletion permissions.
Select the Worksite Setup tool from the Tool Menu in your site.
Find the site you want to delete by performing a search. For example:
Click the Delete button located at the top or the bottom of the screen.
Note: Make sure you do NOT click Hard Delete, as that option will permanently delete the site and all of its files and data.
