Before enabling enable DNSSEC for your domain, keep the following in mind.
Do not change your name servers while DNSSEC is enabled.
If you do, your domain may not resolve.
Before changing your domain name-servers, disable DNSSEC and wait for at least 72 hours before making such changes.
If you change a web host (or need to transfer a domain) and need to move the account/domain to a new server, remove the Domain Server (DS) records from the registrar before you transfer the domain.
Once you have done that, wait for the changes to propagate before initializing the transfer.
Perform the transfer.
Then manually update the registrar with the new DS records.
If you do not remove the old DS records from the registrar, the domains may produce DNS resolution issues due to invalid DNSSEC responses.
