Enterprise Calendar Migration @Zimbra to @Office 365 @MSFTExchange

Per request, a video of  migrating calendars from Zimbra into Office 365.

Of course this keeps meetings as genuine, functional, updateable meetings when they are migrated to the Microsoft Exchange side.

We are reading calendar data directly from the Zimbra database, a technique we also use for our full-state Exchange to Exchange migrations and our Oracle Beehive to Exchange migrations.
