Apple won’t be keeping all of the services in macOS Server after the next few months. In the meantime, we have a big old guide to read. I have some overlapping articles I’ve been working on, but I’d say we’re in a similar headspace. The Apple macOS Server Services Migration Guide is available at https://developer.apple.com/support/macos-server/macOS-Server-Service-Migration-Guide.pdf and covers bind, vpnd, freeradius, manual netinstall with bootp and tftp, apache, wordpress, CalendarServer, and ftp. It’s pretty technical, but nothing too crazy in there!
Overall, an easy read and I’m glad to see some content coming out to help admins!
It is possible to remove all of the content from a Lion Calendar server using Postgres. To aid you in doing so, Apple has built out a couple of commands to make the process easier. This will nuke everything from the server and so is not something that should be lightly done. To do so, first stop the Calendar service in the Server application. Then let’s back up the database:
pg_dump -U _postgres caldav -c -f /db_backups/caldav.sqlThen run dropdb to remove the database itself:
dropdb -U _postgres caldavOnce the database is gone, run the calendar_bootstrap_database script (I prefer doing so verbosely):
calendarserver_bootstrap_database -vNow you should be able to start a fresh, clean calendar database by starting up the Calendar service in the Server application again. Note, this is dangerous if you have production data. Also note that you cannot run the bootstrap until you delete the database.
