New vlan, new lookup zone in AD, what am I missing ???

I have a simple network, all flat, using default vlan 1 on my LAN.  I do have 2 switches that have a different vlan to separate my camera traffic.


I am implementing 2 more switches, stacked, (vlan 90) that I need them to be able to access the rest of my current network, vlan 1.
I'm going to create the new vlan on the core switch and add an IP address to it.  I know that all my uplink ports need to also be trunk ports,
so it can pass all the vlans,  I'm guessing, all I need to do is add the new vlan on every current switch in my network and that's all I have to do from a
networking standpoint.  I also need to add the IP helper command on my core switch, so I can pass the DHCP info to my DCs.  Am I missing anything else
I need to do?

In regards to my AD, I'm running windows server 2012R2 for all 3 of my domains.  I'm running DHCP and DNS.
So I'm assuming I need to create a new lookup zone for this new vlan and IP range.
Besides that, am I missing anything?  What else would I need to do?

Is there anything else I need to do to make this happen?
