I'm a new NE customer trying to convert my Groupwise users over to Zimbra NE 5.0.11 with very little success. I was wonder if anybody has had any luck making this conversion? If so, can you please share how you did it?

When the migration tools runs completely the only warnings I get are about shared folders, which is OK, they don't convert. However, when I log into Zimbra, half the messages are not there, and it is hit and miss with the Calendar. Only the addressbook seems to convert 100%.

I have thought about using IMAPSync, but that doesn't help me with user's Calendars or addressbooks.

Are there any other suggestions on how I might convert 1500+ Groupwise accounts over to Zimbra?
