Hi, 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]. Please keep in mind that when You will move routers to new agent You will have some downtime in data plane.
