<br>
I don’t know if there is any tutorial for that but You can just deploy new node with agents which You need, then disable old DHCP/L3 agents with neutron API [1] and move existing networks/routers to agents in new host with neutron API. Docs for agents scheduler API is in [2] and [3].<br>
Please keep in mind that when You will move routers to new agent You will have some downtime in data plane.<br>

> I Have existing OpenStack with 1 controller node (Network Node in controller node) and 2 compute node. I need to expand the architecture by splitting the network node from controller node (create 1 node for network). <br>
> <br>

> Thanks<br>
