Before you run csrename, you must first:

To run csrename, you must log in as icsuser (or as the Calendar Server runtime user ID specified during configuration). If you run csrename as superuser (root), you might need to reset the permissions for the new database files.

If your Calendar Server installation has a front-end/back-end server configuration, you must run csrename on each back-end server.
