Full-state Calendar Migrations from #Oracle, #Zimbra, #MSFTExchange, etc into @Office365

There must be a forest around here somewhere, I just cannot see it through all these trees.

These are Sumatra's full-state calendar migrations into Microsoft Exchange that 
  • re-create meetings
  • keep recurrence patterns 
  • preserve guest responses. 
  • book conference rooms and resource
  • make it like your users have been using Outlook and Exchange all along. 
  • Everyone else who claims to do calendar migrations skips over all this functionality. To be fair, it is hard to execute correctly (and most of them have their hands full convincing you to do email when imapsync does it so well and so much less expensively), and it's not too important if you have a few hundred users. But it is the whole ball of wax if you're any real-sized corporation.

with Incremental Sync
Oracle Calendar Server to Exchange / Office 365 (via ICS files, which we still use to create live meetings):
Oracle Beehive to Exchange:
MDaemon to Exchange (we don't do full-state on this)
Meeting Maker we've been doing but we didn't do a video on it.  And at this point -- why bother?
