I have been using Zimbra Server for managing my mailboxes for the last seven years. But storing all these mailboxes on Zimbra Server is burdening me with additional costs, which I am unable to bear now. Therefore, I want to migrate my Zimbra mailboxes to RoundCube webmail. I have already exported my entire Zimbra mailboxes in TGZ files. The only thing that I need now is to move these TGZ files into RoundCube account. But unfortunately, I don’t have any idea about how do it. So, if someone could suggest me an easy method for migrating my Zimbra mailboxes to RoundCube, would be of great help. Thank you.
