[Rdo-list] RDO-Manager ovecloud change existing plan, how?

Hi all, I've deployed rdo-manager in a virt env and everything is working fine except the vnc console which is alreday an open bug for that. Now I would like to change some parameters on my deployment, let's say I wan't to disable NeutronTunneling, I wan't to use VLAN for tenants and use 1500 MTU on dnsmasq. So I downloaded the plan: #tuskar plan-templates -O /tmp uuid changed plan.yaml, environment.yaml, provider-Controller-1.yaml, provider-Compute-1.yaml. than I ran the stack: # heat stack-create -f tmp/plan.yaml -e tmp/environment.yaml overcloud The overcloud is deployed fine but the values aren't changed. What I'm missing here? Thanks, Pedro Sousa
