I recently changed my ZCS server (ZCS 5.0.11 on CentOS 5) host name from mail2.domain.com to mail.domain.com using zmsetservername and instructions on the wiki. All went well, and everything worked again after the changes. My server is creating new data in the graphs of the server statistics admin page, but all of the old data that was generated as the old host name is not showing. I assume this is because the old server name is associated with the old data, but the system queries for data belonging to the new hostname.

Where do I go and what do I do to associate the old data to the new server name so that it will be reflected in the graphs? Is that data in the database, or is it in files in the logger directory?
