Zimbra Calendar / Tasks / Contacts to Exchange 2007/2010 Migrations

Update November, 2011.  If you're interested in Zimbra to Exchange calendar migration, see our newer posts on a faster, simpler method.  http://calendarservermigration.blogspot.com/2011/11/faster-easier-zimbra-ics-to-exchange.html

December was a busy time at the Sumatra HQ.

We averaged two migrations a week and got three inquiries about migrating calendars from Zimbra to Exchange -- one of which we consider credible in that they kept a dialog going.

So, after a few weeks of skunk works development (which is an oxymoron here), we've got Zimbra calendaring, tasks, and contacts migrating into Exchange 2007/2010, with full state information intact.

Of course, if you want to take calendar data INTO Zimbra we can still do that. But we are kind of psyched that this is the first calendar we'll take you into or out of.
Keep in mind, you could export your ICS files and import them into Exchange (try it and see if that preserves your guest responses) or you could just move PSTs (again, try it). Our process re-creates the guest lists and responses of the calendar data on the Exchange side and it does it server-side with no end user interaction.
