@Loren Rana da Silva Oliveira ,

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

I see you are trying to move an Azure DNS Zone from one Subscription to another.

I think you are trying to Add your custom domain name to your tenant

And before that, you are also planning to move the DNS Zone to a subscription belonging to the new tenant.

Marcin Policht 's is correct. First you must delegate the DNS Zone in the subscription belonging to the new tenant. Only then will the records you add will propagate.

What is your Domain Registrar?

Make sure you create the DNS Zone in the new subscription. Once added, you will be able to see name servers in this DNS Zone.

Add these Name servers in your Domain Registrar.

Cheers,

Kapil

There is no need to assign a custom DNS domain to a different Entra ID tenant if you need to create a CNAME record in it for an App Service web app.

Then make sure to properly configure delegation - as described in https://learn.microsoft.com/en-us/azure/dns/dns-delegate-domain-azure-dns
