Frequently Asked Questions

Can I downgrade my Zimbra server ie. rollback a version?

No, this is not possible. Software packages, configuration and data storage is updated when an upgrade is performed and this cannot be reverted.

Can I install Standard or Professional mailbox licenses on our existing Zimbra Open Source Edition server?

No. Zimbra Standard or Professional licenses cannot be installed on an existing Zimbra Open Source server. The Zimbra Open Source must be upgraded to the Zimbra Network Edition software. All mailboxes, directory and data is preserved during the upgrade.
