Is there a way to redirect a site's DNS from one NS to another?

Question

Domain Name System

Guys, such a question ... In the title, I probably did not quite describe the problem.
And the problem is this:
People have lost access to the domain. He registered once for another person. Login password lost. They only throw money into the account for auto-renewal of the domain. But that's not the point.
On this domain ns of the server are specified masterhosts. And the site is there, ok.
Comrades unknowingly ordered a site in one of the studios, they made a site for them, and now they need to CHANGE ns from the master host to these studio ones. So here they are cleverly arranged.
Now a question. Since I myself am not in the tooth with my foot at all.
Is it possible somehow on the masterhost in the settings of the DNS zones to make the site delegated further, not to the masterhost, but there, to the servers of the new studio?
I probably stated it in a sloppy way, you'll forgive me.

Answer 1

And what for on DNSY of this studio to change? You, judging by the question, have access to editing zones on ns's of the master tail, well, just write zone A to the desired address.

Answer 2

Yes, it is enough to register the A record of the corresponding hosting on the masterhost in the DNS editor.
as a second option to upload the site to this server
as a third option to restore access by writing an application and providing the passport data of this long-sufferer, if they are still somehow there.
There is a hemorrhoid option to go to court with a statement on the recognition of ownership of the domain, but it's hard to say.
as an extreme option, you can already use it on the server itself
1. use proxying that is configured in .htaccess to another server. perverted but it will work.
There is also an option to buy another domain and glue them into .htacess existing visitors will go to the new domain.
And even a bird can stick together, but the weight and reference mass will sag.
if you still have access to the DNS editor, then you can register a redirect through CAME.
Well, it’s not entirely clear why you need the dns of this studio?
