How to Upgrade OpenStack from "Grizzly" to "Havana" ?
Hi all.
I just installed recently OpenStack "Grizzly" on Ubuntu Server. It is up and running.
I just seen OpenStack "Havana" has been released.
Is it posible to upgrade my existing OpenStack "Grizzly" to OpenStack "Havana" or do I have to install "Havana" from scratch ?
If it is possible, What do I have to do ? Do I have to install only the new modules on "Havana" (Heat, Metering ...)
Thanks a lot in advance.
