What Customers Are Saying

SysTools Zimbra to Office 365 Migration Tool – Verified Reviews

“Our organization was looking for a way to ditch the self-managed Zimbra Server and transition to the M365 cloud but was unable to find a way to perform the migration. Thanks to the SysTools Zimbra to Office 365 Migrator the entire process became easy and we were able to complete the transfer in a few simple clicks. ”.

Mark, IT Head

London, UK

My initial hesitancy about migrating our sensitive Zimbra data over to Office 365 was put at ease thanks to the advanced security feature of this tool. As it uses admin credentials at both migration endpoints the risk of data leakage was effectively zero. Moreover, as no user passwords were needed the migration happened non intrusively. We did a test migration first, and everything came across perfectly – all emails, contacts, and calendars. No data loss, no corruption.

Peter, Security Admin

"The user-friendly design and transparent migration process of the tool allowed us to monitor the migration from start to end. The clear progress indicators in the form of item count and data volume gave real-time updates on the migration status. Moreover, even when some emails arrived during our first migration run the Delta migration feature was able to handle it. This made my job a lot easy a 5 out of 5-star rating from us."
