I'd like to attempt an upgrade from Ocata to Pike soon, and I was wondering if anybody here has any experience to share. Any success or failure story, or general advise would be welcome :) My setup is fairly basic: Keystone, Horizon, Neutron, Glance, Nova, Cinder, Swift
Hello everyone, I was able to update successfully.
Here are the steps:
UPDATE OPENSTACK VERSION OCETA FOR PIKE UBUNTU
UPDATE OF THE CONTROLLER Node
1) PAUSE ALL SERVICES service glance-registry stop service glance-api stop service nova-api stop service nova-conductor stop service nova-consoleauth stop service nova-novncproxy stop service nova-scheduler stop service neutron-server stop service neutron-linuxbridge-agent stop service neutron-dhcp-agent stop service neutron-metadata-agent stop service neutron-l3-agent stop service apache2 stop
2) REMOVE THE OCATA REPOSITORY add-apt-repository --remove cloud-archive:ocata
3) ADD THE PIKE REPOSITORY add-apt-repository cloud-archive:pike
4) UPDATE PACKAGES apt-get update apt-get upgrade
5) FORCED OPENSTACK PACKAGE UPDATE apt-get install list of all packages not installed
6) ACCEPT THE INSTALLATION AND SUB-SUBSTITUTION OF THE CONFIGURATION FILES (A COPY OF THE PRESENT CONFIGURATIONS SHALL BE MADE) Choose the option: Y
In my case, the substitute archives were:
/etc/nova/nova.conf /etc/keystone/keystone-paste.ini /etc/keystone/keystone.conf /etc/neutron/l3_agent.ini /etc/neutron/neutron.conf /etc/neutron/plugins/ml2/linuxbridge_agent.ini /etc/neutron/metadata_agent.ini /etc/neutron/dhcp_agent.ini /etc/neutron/plugins/ml2/ml2_conf.ini /etc/glance/glance-registry.conf /etc/glance/glance-api.conf /etc/openstack-dashboard/local_settings.py
Note: The old configuration files have an extension: .dpkg.conf
7) COMPARE THE SUBMITTED FILES OF ITEM 6, WITH THE FILES .dpkg.conf MAKING THE CHANGES NECESSARY
8) UPDATE DATA BANK su -s /bin/sh -c "keystone-manage token_flush" keystone su -s /bin/sh -c "keystone-manage db_sync" keystone su -s /bin/sh -c "glance-manage db_sync" glance su -s /bin/sh -c "nova-manage db sync" nova su -s /bin/sh -c "nova-manage api_db sync" nova su -s /bin/sh -c "neutron-db-manage upgrade heads" neutron su -s /bin/sh -c "nova-manage db online_data_migrations" neutron
9) REMOVING UNNECESSARY PACKAGES apt autoremove
10) RESET SYSTEM reboot
UPDATE NODES COMPUTER
1) PAUSE ALL SERVICES /etc/init.d/nova-compute stop /etc/init.d/neutron-linuxbridge-agent stop /etc/init.d/neutron-linuxbridge-cleanup stop /etc/init.d/ceilometer-agent-compute stop
2) REMOVE THE OCATA REPOSITORY add-apt-repository --remove cloud-archive:ocata
3) ADD THE PIKE REPOSITORY add-apt-repository cloud-archive:pike
4) UPDATE PACKAGES apt-get update apt-get upgrade
5) FORCED OPENSTACK PACKAGE UPDATE apt-get install list of all packages not installed
6) ACCEPT THE INSTALLATION AND SUB-SUBSTITUTION OF THE CONFIGURATION FILES (A COPY OF THE PRESENT CONFIGURATIONS SHALL BE MADE) School option: Y
In my case, the substitute archives were: /etc/libvirt/libvirtd.conf /etc/ceilometer/ceilometer.conf /etc/nova/nova.conf /etc/neutron/neutron.conf /etc/neutron/plugins/ml2/linuxbridge_agent.ini
7) COMPARE THE SUBMITTED FILES OF ITEM 6, WITH THE FILES .dpkg.conf MAKING THE CHANGES NECESSARY
9) REMOVING UNNECESSARY PACKAGES apt autoremove
10) RESET SYSTEM reboot
I finished the upgrade from Ocata to Pike, CentOS7, installed manually. I wanted to share the experience.
The basic upgrade procedure is pretty simple:
yum install centos-release-openstack-pike
yum-config-manager --disable centos-openstack-ocata
yum update
After that, updating the database for each service:
keystone-manage token_flush
keystone-manage db_sync
glance-manage db_sync
cinder-manage db sync
nova-manage db sync
nova-manage api_db sync
neutron-db-manage upgrade heads
nova-manage db online_data_migrations
cinder-manage db online_data_migrations
The issues I found after restarting:
1) The Horizon dashboard wouldn't open. You have to add "WSGIApplicationGroup %{GLOBAL}" to the top of /etc/httpd/conf.d/openstack-dashboard.conf to fix it
2) Swift logging in the default installation is going to local2 (old version was local0), so all my swift logs were landing on my /var/log/messages instead of /var/log/swift/swift.log. To fix it, edit /etc/rsyslog.d/openstack-swift.conf and change the rule to local0 instead of local2.

Hi Jep, I have recently managed very easily an upgrade from Mitaka to Newton. My cluster was running on a CentOS and I followed this: http://bit.ly/2ftuyc8 After stopping the services, I have enabled the Newton repos and disabled the Mitaka ones. Then upgraded the packets and restarting the service.
