null value in column "name" violates not-null constraint

On a brand new installation, after configuration, I try to connect using a "to-be-migrated" username:

@drzraf Actually, it is not a bug. There are two kind of user in modoboa: those with a mailbox and those without. For the first category, we force usernames to be valid email addresses because they must be unique (otherwise dovecot and postfix will complain). In your example, the username is not an email address so it fails.
