For local calendars, you can create CalDAV accounts and simply upload the users events into their respective CalDAV accounts. To automate this, something like curl would be fine, just PUTing each one. Since they are local calendars, these events should be all non-scheduled (i.e. no attendees), so there's not much to worry about in the way of relationships to other data or users.

I don't think I can easily explain this, as it's quite complicated. If you have a Lion server, look at:

In the past, it has been possible (generically, not necessarily with calendar stuff) to manually invoke these migration scripts to get the job done, provided you have set the stage properly. Perhaps that can work here as well...
