    You are not saying when you change the A Records of ns1.somehost.xyz & ns2.somehost.xyz

    That is more important than the records in the registrar.

    Hi, the A records on SERVER_OLD will always point to 1.2.3.4, whilst the A records on SERVER_NEW will point to 6.7.8.9. I'm thinking that as the Registrar holds the assocation for ns1.somehost.xyz and ns2.somehost.xyz pointing to 1.2.3.4, SERVER_OLD would be used to handle queries, until such a time that the glue record is updated to use SERVER_NEW 6.7.8.9?

    Cheers

    I'd say that you are overthinking this situation.

    Just transfer the somehost.xyz to the new server, make sure that IPs of the ns records in new AND old server point to the new server IP, and change the IPs in registrar.

    After that you should wait at least 48 (or even 72) hours before you close the old server.
    Changes to DNS records will take from 12 to 72 hours to become effective while the new DNS records are propagated worldwide.
