DNS Migration to F5 DNS system

Hi F5 Community,

We are planning to migrate from ISP External DNS to F5 DNS.

Questions:

Would there be any problem if we will just define only F5 wideip object then put as NameServer the F5 Listerner IP in the registrar or we have to migrate all DNS record type like MX, PTR, CNAME, and others to that particular zone file to our F5 DNS before we define it as NS Server in Registrar?

Thanks in advance.
