Thank you @lalajee for your feedback:

I copied your answer to be able to validate it and close the thread.

The solution :

I got the information by turning on Debug logging

Click Start>Administrative Tools>DNS to open the DNS management console.

Tip: On previous Windows Server versions, click Start>All Programs>Administrative Tools>DNS.

In the navigation menu, expand your DNS server, right-click the server, and then click Properties.

Click the Debug Logging tab, and then confirm these options:

Click Cancel to close the DNS Manager window.

The Windows server is configured to log DNS packets.

Wireshark could be useful in this regard.

Hello,

Here are several steps you can take to verify whether all DNS records have been successfully moved：

First you could verify and review if all the DNS records are listed in DNS management tools on the new DNS servers.
If you want to check if all the clients are using the new DNS server, you can search for a script to gather this information remotely.

Here are two websites that provide script resources: https://www.powershellgallery.com/ https://github.com/

Alternatively, you can create a new post and include the PowerShell tag to see if anyone with expertise in PowerShell can offer assistance.

If you are using DHCP, check the DHCP server settings and confirm that it is assigning the new DNS server addresses to clients.
