Hi, I had installed Grizzly release of openstack on my machine using the following link. https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_SingleNode/OpenStack_Grizzly_Install_Guide.rst I no longer need the grizzly release. I want to install the Havana release. Can someone please let me know how to uninstall the Grizzly release. If this is not the forum for me to post this query, can you please let me know to which mailing list should I send this query. Thanks, Lalitha.M =============================================================================== Please refer to http://www.aricent.com/legal/email_disclaimer.html for important disclosures regarding this electronic communication. ===============================================================================
