Although it is recommended to perform the migration using the wizard, a simple command-line utility is also available. The tool is the 4d2kms command line utility. It is necessary that the utility is run by a user with valid access to the 4D Mailbox server’s configuration. If the utility is started with parameters missing, the following brief instructions appear.
