I'm assuming you mean Dynamic DNS?
Firstly, make sure that NIOS permits the domain controller IP addresses to update the Active Directory DNS zone (including the _ subzone). Yes, GSS-TSIG may be more secure but it also brings risks for when it goes wrong. This is done on the DNS zone configuration in NIOS. Edit the zone and go to "Updates" where you can set a list of IP's (or, even better, an ACL)
For DHCP updating client records, recommendation is to disable clients from updating DNS (this is the default with Windows but allows too much privilage). Better to configure the DHCP servers to update the DNS zones as they hand our leases.
Under UI > Data Management > DHCP >Networks > (on the right) Grid DHCP Properties you can set IPv4 DDNS.
If NIOS is both DNS and DHCP, disable "Update DNS on DHCP Lease Renewal". That setting should only be used when NIOS DHCP is updating Microsoft DNS.

Hi! Thanks for the answer.
After this configuration, will user authentication continue to work? If there is a need to put more machines in the domain, will it work by directing DNS to the Infoblox IP?

If done correctly, then yes. The endpoints authenticate directly against the Microsoft Domain Controllers. They use DNS to find the Active Directory servers using SRV record type queries as per this page: https://petri.com/active_directory_srv_records/
You may find that you have to leave the "Return minimal responses" disabled (Grid > Data Management > DNS > Members/Servers > [Edit Member ] > General > “Return minimal responses”)

Is there a step-by-step guide for this migration?

I'm not aware of one.
If you haven't done it before, I recommend a conversation with professional services. Either Infoblox's own or that of a certified partner. They can get familier with your environment, specific requirements and identify any issues that may arise.

Hello,
To dynamically update DNS records after using the Data Import Wizard (DIW) to export records to Infoblox, you can follow these steps: instantink.hpconnected.com
Enable Zone Transfer: Ensure that zone transfer is enabled on your existing DNS server.
Create an Authoritative Zone: Set up an authoritative zone in Infoblox for the domain you're migrating.
Import the Zone: Use the DIW to import the DNS records from your existing setup to Infoblox.
Configure ACLs: Set up Access Control Lists (ACLs) to allow updates from your existing DNS servers to Infoblox.
Point DNS to Infoblox: Configure your existing DNS servers to use Infoblox as the preferred DNS server.
Update DHCP Settings: Ensure that your DHCP servers are configured to send dynamic DNS updates to Infoblox.
This should help keep your DNS records updated dynamically.
Best Regards,
Michael Gardner
