When you opt for the No Discovery mode, ME DDI Central enables you to add new empty DNS servers, DDI Central prompts youto fill in a special field called DNS Domain Migrations. When using this special field, it is necessary to skip the discovery phase. This is done by selecting No for the Discover Existing Configurations option.
This approach is particularly advantageous when integrating a new DNS server that manages a vast number of domains. These domains can be added to your existing cluster as either primary or secondary.
The DNS Domain Migration mode facilitates the rapid inclusion of all domains or the selective migration of specific domains from the server being added. If you choose None, the new DNS server will be incorporated into your DDI Central cluster without any domains, allowing you to configure zones and other settings manually at a later stage.
To proceed, select whether the domains of this particular server should be recognized as Primary or Secondary within your cluster, and click Save to begin the migration process. As this can take some time, it is advisable to wait for further prompts or indications on the screen before proceeding.
