I would like to move my personal domain (used for email, dynamic IP subdomains) from another DNS hoster to dynv6 but would like to avoid any mishaps and downtime.
I would thus like to setup the exact same DNS records from the current DNS hoster at dynv6 before delegating my domain to dynv6. Preferably querying dynv6 DNS servers directly and comparing the responses to the response of the current DNS server and only then delegating my domain to dynv6 nameservers.
The pre-population of DNS records would also make sense in order to use dynv6 as a backup DNS server.
Is there a specific reason for requiring domain delegation before allowing configuration of the zone?
