Changing the namespace name
You can change the name of a namespace any time, except while the S3 compatible, CIFS, or NFS protocol is enabled for the namespace. However, when you change the name, the URL for the namespace may change as well.
When you change the name of a namespace, AD single sign-on is automatically disabled for the REST API for that namespace. You can reenable it any time after the name change (as long as HCP can communicate with AD).
