I am currently deploying openstack wallaby using tripleo method, and my overcloud is up, now i want to change the overcloud domain specified in the udercloud domain and then redeploy the overcloud again.

So if I change the undercloud.conf to the new domain and run openstack undercloud install, will it affect the already inspected nodes, provisioned network, ceph and nodes? Do I have to do introspection and other activities again?

My plan was to : 

1. change the domain in undercloud.conf

2. run openstack undercloud install (hoping it doesn't affect anything else and just updates the domain name)

3. redeploy overcloud stack only using openstack overcloud deploy (no introspection, no node provision and other activities ).

With regards,
