Can we move invited appointment to an existing calender folder?

[xingjing]

Hi,

I am migrating our institute calendar to zimbra. We would like to move all appointments from our old calendar application into each user's specific calendar folder such as "Appt from Old Calendar". I can create soap envelops by specifying which folder to send the appointments for the organizers, but all attendees get the invitation in their default calendar. I could not find a way to move the invited appointments to their "Appt from Old Calendar" folder. Am I missed something? Or is there any soap envelops I can create so I can move the invited appointments to the folders we wanted?

Any help is greatly appreciated.
