Sumatra Undo in Action

Ever since high school film strips we've been convinced that visual aids are the most effective.

And ever since college we've been convinced that designing a software system without a back out strategy is just darned irresponsible.

So we combined both of these lessons in our video of Sumatra's UNDO capability in action.

Zimbra to Exchange Calendar Migration - The Video

We've had a good response from one of our test sites on the faster, simpler Zimbra to Exchange calendar migration method so we did a video of the process to show you in real time how it all works.

Enjoy.

And if you want to see the full screen version, you can watch that off our website.

Faster, easier Zimbra ICS to Exchange migration

UPDATE: June 2015.  We've modified the faster-simpler ICS method so that it's faster-simpler AND full state (works like aces for Oracle Calendar Server! and in this case Zimbra gives us the recurrences already so we're one step ahead.)  We can do it for Zimbra if there is sufficient enterprise-level interest.

One of the developing trends we've seen is sites moving out of Zimbra and into Exchange.

Imapsync is excellent for moving the email, but the calendars, tasks, and contacts are another issue.

While we've have a full-state migration solution for over a year, a lot of the folks who want to move want something simple, but still server-side, and oh, could we PLEASE keep meetings live?

It's a tall order, but as usual we deliver.

This is the basic screen:

In short what you do is export your Zimbra calendars, tasks, and contacts server-side (using either zmmailbox, cURL, or whatever you're comfortable with) in ICS and VCF format, then run this application against the resulting files.

With the proper credentials on your Exchange server (and yes, we have tested it against Office 365 and Live @ Edu), these will upload.  Meetings will be re-proposed (so your users will see invitations in their inboxes come the Monday morning post-migration).  The alternative is the full-blown Sumatra process which is overkill for many of you moving out of Zimbra.

Rather than our three step process (export, map user IDs in a database, and insert into Exchange), this is a TWO step process (export, import) with no intermediate mapping.  So if you're changing a lot of user IDs going from Zimbra to Exchange, this is probably NOT the recommended process for you.

We're in test right now with this at a couple of sites and will let you know when it's ready for prime time.  We'll give you the full documentation set and a video then too.
