Make sure that Kerio 4D Migration Wizard is installed on the computer where the 4D Mail server is running and that the IMAP service is also running at the server.

Install Kerio MailServer on the same computer or on a host accessible via a network interface. During the installation, create a primary domain and an administrator’s account. The primary domain should not be equal to any of the SMTP domains at the 4D Mail server.

The migration tool will migrate all users from 4D Mail to Kerio MailServer. Check that users are allowed to login and they have valid passwords. Users with login disabled or without valid passwords will not be migrated.

Run Kerio 4D Migration Wizard. You will be asked to enter the administrator‘s password since rights for administration of the operating system are required for the migration process.

The migration tool is now running.

Figure 4.1. Introduction

Click on Continue to make the migration tool locate the configuration at the WSMailboxServer.prefs.xml file in the default path /Applications/4DWebSTAR/MailboxServer. If this file cannot be located, you will be asked to enter a correct path to the file. If the configuration is located automatically, the page shown at figure 4.2  Locate 4D configuration is skipped.

Now, the migration wizard attempts to connect to the IMAP service at the local host’s default port 143. If the connection fails, check whether the IMAP service of the 4D Mail is running on the computer. If not, go to the migration tool and define the port where the IMAP service is running.
