I'm configuring a new mini with Yosemite + Server 4, desiring to retire an older mini with Mavericks + Server 3. I've found a problem with the Contacts and Calendar servers -- how do I move them over? There are only two accounts using these services. I originally expected to just do an export--archive on the client systems and then import back with the server changed, however apparently the action of doing the import adds the old server back in and restores to that. I also tried to just change the server address but that doesn't work either. Any suggestions? And baring that, how about a way to move it all to iCloud -- I don't really need to run these services on my own anymore.
