ZxMig vs ZxBackup
We are preparing to migrate our Zimbra mailserver to a new Zimbra mailserver
and did a test using ZxMig and a data ferry (usb hdd) but this is rather slow.
I've read in ths forum about using ZxBackup to ZxBackup which is supposed to be much faster.
What would be the best approach to migrate and reduce downtime to a minimum ?
Please keep in mind that the total size of our mailboxes is ~780GB
