Using Infoblox DNS with Windows Server 2016 AD Integrated DNS

soonhin you will likely break dynamic updates if you do not set this up to allow for authenticated dynamic updates. 

Infoblox has lots of white papers about integrations into AD/DNS environments https://www.infoblox.com/wp-content/uploads/infoblox-white-paper-Infoblox-and-the-relationship-between-dns-and-active-directory.pdf 

Domain services use DNS as the primary locator service (SRV records) so day 1 if you duplicated your zones you would have little to no issue, day 10 you will see lots of breakdowns as workstations will not update DNS dynamic records, domain controller SRV records will become stale. New DCs when added will not register correctly. 

If you purchased these from Infoblox I'd go back to your rep and request documentation on how to correctly migrate away from integrated zones.
