Hi James

I do not think there is any upgrade procedure at the moment
if you deployed a nosdn-nofeature scenario, I assume it is a pure OpenStack Fuel upgrade but usually such upgrade means reinstallation of version N+2 aside of version N then migration...

such upgrade (especially from version N to version N+2) has been identified as a major pain points by the End user Advisory group. A project named escalator had been created some time ago for this purpose https://wiki.opnfv.org/display/escalator
but as you can see it is not very active at the moment ..

the topic is pretty complex...

during the last OPNFV summit there was a presentation from kddi/NEC/Redhat "Software-Defined Migration: How to Migrate Bunch of VMs and Volumes Within a Limited Time Frame" https://www.youtube.com/watch?v=_6kB1NTob8o

Hi all

We have OPNFV Brahmaputra release up and running well for a year now. Fuel deployed Openstack Liberty and it is hosting a good number of instances. We haven't created any advanced nfv solutions yet, but it is where we will be heading one day.

My task current to upgrade to OPNFV Danube/Newton. But I can't find a path/process on how to do this.

Can someone direct me with some high level steps or a document to follow?

I am confused if I should treat this as a Openstack Fuel upgrade, or if there is an actual OPNFV specific Fuel upgrade.

Also, once I get Fuel upgraded how do I get the existing environment/Openstack nodes upgraded (to Newton)?

Should I upgrade to Colorado/Mitaka first, or no?

Thanks for any advice you might give!!
