Ftp user without domain name in it

  • I need to migrate from ispconfig to i-mscp panel a customer.
    He had an ftp access to old ispconfig server. He has many devices who sent backup file with this configuration. Example: ftp.domain.ext, user: nameuser pass: password.


    I need to know if I can migrarte domain.ext to i-mscp and add an ftp user, without domain name, to allow ftp access, because all his devices are not close to his office, and he cant reconfigure by remote.


    It could be an alias of another ftp@domain.ext user ? How I can do it ?
    Thx for any suggestion or reply.


    I need to shutdown that server. :D
