Hi, I'm performing an openstack upgrade from Havana to Icehouse. I'm following this guide.

My approach (as I could not stop services and do the upgrade task directly) to try creating another machine with controller role, copying there the DBs and then start the management services.

Now I started with keyston, it seems to work correctly (no errors in log files), but when I sourced the same rc file as in the previous controller (changing only the controller IP) and performing a keystone user-list command it returns:

Invalid OpenStack Identity credentials.

Thanks!

UPDATE

Any hint? I could not find any useful answer.
