Clean Install 10.8: How to Migrate User Data?

I'd like to do a clean install of Mountain Lion 10.8 Server and migrate the user data, but I'm not sure how.


In specific for each user:

  • iCal calendars and events
  • Mail IMAP messages and folders
  • Address Book contacts and groups
  • And I think that's it


The data was originally set up in Snow Leopard 10.6 Server, but has since been upgraded to Lion 10.7 Server. I mention because I think that has bearing on the storage location.


I suppose I could do an Address Book export. I've attempted to re-import iCal before and the server ends up wanting to send calendar events to every invitee ever listed. I'd like to avoid that scenario again.


For Mail, could I keep the client-side IMAP folders as-is and then add the new 10.8 IMAP account to Mail before dragging over the whole folder structure? Or should I move it to "On My Mac" first and then do the same? Or is there a server-side way of moving the data store to the newly-installed server?


Thank you!

    HI Bailey, the best way to do this is to clean install OS X Mountain Lion, then during the ML OS X setup, migrate everything from your Lion volume. After the OS install/setup/migration is complete, install Server on the ML Mac and it will finish migrating server data for all users.

    If you changed service data locations previously, the migration won't reset them. The server migration will upgrade older data to the formats it needs for ML.
