Changing Primary Grid DNS to another grid member

[#1]

Hi everybody,

I have to decomission my actual Grid Master that also is the Grid Primary DNS of my authorized dns zones. I have already promote to grid master another grid member, but the old Grid Master still is the Master DNS of my private authorized zones.

How is the correct way to change the Master DNS rol to my new Grid Master node ? I need to do it because then I have to delete the old grid master from the grid (it is an unsupported Trinzic hardware version).

I want to do it without impact on the DNS service. I'm thinking to configure the new Grid Master as a second Primary Grid Master DNS (to get a multi master) and then once the new master dns has the dns database, delete the old one. Do you think this will work ? Any ideas about wich is the best way ?

Thanks in advance.

Oscar.
