Migrating and copying calendar/reminders data between servers

Hello everyone,

Apple has released a guide explaining how to migrate and copy wiki data between servers :

http://support.apple.com/kb/HT5082

Is anybody aware of a guide (not necessarily official) explaining how to do the same for

- personal calendars

- wiki calendars (they are not migrated using the guide mentioned above)

- personal reminders

- wiki reminders

Any help will be greatly appreciated !
