Renaming an asset on Cascade CMS will change its system name. The system name is the name that shows up on the site's URL and the left-hand asset tree in Cascade Server. System names should ONLY contain lowercase letters and dashes.
Example
Before the change
The System name is displayed in site's URL
The System Name is displayed in Cascade Server's asset tree
After the change
The System name displayed in site's URL
The System Name displayed in Cascade Server's asset tree
