One of our customer wants to migrate from Kerio Connect Mail Server 8.0 to ZCS NE 8.0.2.
The customer has over 3500+ mailboxes. Most users access only webmail, some use MS Outlook with Kerio Connecter.
From the Zimbra WiKi i found that imapsync is capable to transfer only mails (Mail Migration - Zimbra :: Wiki)
While doing a test, first time it transferred fine(with all folders), but subsequent runs are giving errors. please see the attached log.
can anyone guide me to do a transfer properly?
I need to transfer mails (all folders),contacts and calenders+tasks.
