In other words, we add a new mail storage to the Zimbra infrastructure, which has already been updated to the latest version, and then we simply transfer accounts from the outdated server following a familiar scenario and repeat the process until all servers in the infrastructure are updated.<\/p>\n<p>This method allows for a one-time transfer of accounts, thus reducing the duration during which mailboxes will remain inaccessible. Furthermore, only one additional mail server will be needed for its implementation. However, administrators should approach its use with caution when deploying mail storages on servers with different configurations. The reason is that transferring a large number of accounts to a weaker server may negatively impact the availability and responsiveness of the service, which can be quite critical for large enterprises and SaaS providers.<\/p>\n<p>Thus, thanks to Zextras Backup and Zextras PowerStore, the Zimbra system administrator can update all nodes in the Zimbra infrastructure without any risk to
