Will my new config would look like this? will it be a Slave for my new
servers?

ns1.example.com    1.2.3.4        ---------------> Master
> ns2.example.com     5.6.7.8    -------------->Slave
> mynewns1.example.com   20.20.20.20   ----------> Slave
> mynewns2.example.com   30.30.30.30  ------------>  Slave
