Zimbra to Exchange / Office 365 Calendar, Contacts, Tasks migration again field-proven

Once again we've migrated a domain from Zimbra to Exchange 2016 -- calendars, contacts, and tasks.  They also followed our guide to Zimbra email migration with imapsync.

This in itself is not noteworthy.

What was different about this was it was a municipality running at small scale (100 accounts) and they took the lead on running the migration themselves with little input from us. So they could keep their costs down while still getting a high quality calendar migration.

To quote them:

The migration went off without a hitch – no complaints that I have heard about missing items.  Thanks so much for the helpful tool!

Huzzah!

The system works!
