I had a perfectly running installation of OpenStack Kilo (with Sahara) but because of some issue in my current subnet I had to move all the my physical servers to another subnet so is there a way to change the IP address of the controller & compute nodes after the installation is done?

Yes we can change that. If you configured OpenStack with hostname that should be easy else it may difficult to change the IP's.

Thanks for the answer. There are some places where I used Hostname so they are all fine but there are some config files like neutron where I hardcoded the Tunnel network IP's in controller as well as compute nodes. So, I am having hard time in making my setup work again after changing the IP's.
