Migration tools enable migration of data stored at the 4D Mailbox server. The migration covers domains, user accounts and data available through IMAP (e-mail and folders).

First, the migration tool locates 4D Mailbox server's configuration in the default or a specified path. Then, it attempts to connect to the IMAP port at the local host and to login to Kerio MailServer using an administration account. If all these attempts are completed successfully, the migration process can start.
