Renaming a content class
You can rename a content class at any time. Renaming a content class has no effect on the associations between namespaces and that class.
Procedure
On the Search page, in the list of content classes, click the name of the content class you want to rename.
In the Name field in the Settings panel, type a new name for the content class.
Click Update Settings.
If you also modified the list of content properties for the content class, clicking Update Settings commits those changes as well.
