There are only 2 or 3 commercial vendors that have products that can migrate all data from Zimbra. We chose Cloud Migrator primarily because it’s a locally installed product (required by privacy legislation for us), but in terms of features, it compares well
with the other major product. We did talk with another large university that had already used it successfully for their migration.

<div class="">I don’t think we’re allowed to share what we paid for it, but it was substantially less than their list price. We got a discount for being an academic institution, and then we got a really good rate for our students (had we not gotten that rate,
we would have only used the product for our staff/faculty accounts and just used imapsync for student mail data and not bothered with their calendar/task/contact data)<br class="">

<div class="">Many thanks. Need to investigate some more if they are to be trusted, as I have never heard of theme before. What pricing did you get on it? we dont have that many users. about 1000users. and many of those are also overhead beacause of users in
and out.</div>

<div style="overflow-wrap: break-word;" class="">Sorry, I should have clarified - it uses EWS to talk to Exchange, but native Zimbra SOAP to talk to Zimbra. We migrated from v8.7.1, but it does support older versions.

<div class="">You don’t need to change any passwords - just create an admin user on each side. Their knowledge base gives info on what permissions each admin user needs. On the Exchange side, I believe they need to explicitly be granted the “Impersonate users
and applications” right, or something like that. On the Zimbra side, I think a standard Zimbra Admin role will work. I had to do more than that, but that’s because I also ran an imapsync pass to migrate folder names. The migration tool doesn’t migrate empty
folders, so we had some complaints about that.<br class="">

<div class="">Interesting. what version of zimbra did you test that with. we got EWS on our 8.6 (some mac users are using it). but not sure how well it would play in a migration situation.<br class="">
Do the tool you mention use a admin password to migrate or do one need to reset all users password in the prossess?</div>

<div class="">We migrated ~60,000 users from Zimbra to Exchange on-premise last year using Cloud Migrator (<a href="https://cloudm.co/" target="_blank" class="">https://cloudm.co</a>). It uses standard Exchange EWS calls to migrate the data, so it doesn’t matter
whether you’re migrating to on-premise or cloud (it was designed for the cloud, obviously). It worked reasonably well. Email, calendar, tasks, contacts, and tags were all migrated smoothly. Rules can’t be migrated, unfortunately, probably partly because Zimbra
rules (which are actually good) don’t map well to Exchange rules (which suck). Their license is a per-user license <br class="">

<div dir="ltr" class="">What tools/methods do people use when migrating data from zimbra to for example exchange?
<div class="">Calender and emails are the most important ones to get over. Rules would also be good to get over and tasks are a bonus. </div>
