Zimbra ships with its own Exchange Migration tool, and there are multiple thrird-party commercial entities that do the same as well, including Audriga, who recently presented at the North American Zimbra Partners' Conference in Texas. https://www.migrate-mail.com/en.html

Hope that helps,

We will be doing exact same thing using ZCS Migration Wizard for Exchange
https://www.zimbra.com/downloads/zimbra ... ion-tools/

Test on few accounts confirmed that migration with this tool is working - mails, addresses and calendars were succesfuly transfered to Zimbra.

Can you tell me how the migration is going?
We too are migrating an Exchange 2013 to ZCS8.8.10 via migration wizard and yes, migration works, message calendars and contacts are moved, but terribly slow.
And slow means something like one element (emails contacts or appointments, without difference even in size) every two or three seconds.
I've tried anything: using a phisical Windows with Outlook 64b, moving the Win machine on the same subnet, and even using a VM Windows on the same network of the Exchange (no cable, no fw between), but nothing speeds up.

I found this prehistoric thread, without answer viewtopic.php?t=45426 so I think it's not a spot problem, could it be an Exchange feature.
I think it's an Exchange limitation, something equivalent to the zimbra DosFilter, but i don't know Exchange so deeply.

I've not tried imapsync, but it's the next step to check.
Are you experiencing any slowness?
