I believe you wish to export or move data from one IMAP server to another without losing any information. So I suggest using the eSoftTools IMAP Backup Software. This application allows you to simply move from one IMAP server to another, such as Zoho Mail, Gmail, Yahoo Mail, Yandex, Office 365, Outlook.com, and AOL. It can also convert emails from IMAP Server to Outlook PST, EML, MSG, HTML, EMLX, MHTML, MBOX, and other formats.
