IIRC, the username is part of the calendar ID and maybe all the event
IDs. Since I guess you're using the SQL calendar backend, the
username might be abstracted into a separate column that you could run
a simple update on, but I don't remember if the suggested schema works
that way or not. You should post your schema at the least (and
possibly even a sample entry for the user for each table) if you want
that kind of suggestion/help.
