- A prompt will appear requesting permission to export the key for the certificate from the keychain into the Server.app. Choose Always Allow.

- Enroll or re-enroll devices with Profile Manager.
Changing a server's host name may adversely affect the services running on the server and the clients that use those services. Some services may be unavailable or only partially functional after changing the hostname. All devices already enrolled with profile manager will have to be removed from the Profile Manager administration website and then re-enrolled after following the above steps.
Before changing the hostname, consider making a full backup of the server.
