7/31/2007 Electronic Calendar Purge
On July 31, 2007, all Calendar entries prior to July 1, 2005, will be purged from the system as part of the yearly maintenance that we perform on the Calendar database. If there are entries prior to July 1, 2005 that users wish to keep, they must export them from the Calendar server using the file/export command within the Calendar client prior to this event. I suggest exporting to iCal format, though other formats are available. Additional instruction available at http://www.vpaf.uni.edu/tss/documents/oracle_cal_archive_mtgs.pdf
If users re-import that exported data into the Calendar server after the purge has taken place, take note that entries that were marked as private will become public. My suggested workaround for this is to not re-import this information but rather use Outlook, Apple's iCal, or Mozilla Sunbird http://www.mozilla.org/projects/calendar/sunbird/) to open the exported iCal file locally.
Again, this only affects data over 2 years old, entries prior to July 1, 2005.
