Michal/Grzegorz/Will – Can you pls work with Dave to make sure all of the 
Liberty improvements are included?

Dave: The Enterprise WG has been focused on rolling upgrades and developed 
tracker for our work from Kilo to Liberty to Mitaka. You can find the info

 The Product WG has prioritized this user story and we are collaborating on 
continued implementation. We have weekly team meetings if you’d like to come in 
for a discussion on this tag, happy to add this to an agenda. The meetings are

Sure, I can take a pass at this.

Hi all,

One of our long mooted tags has been something that captures the ease of 
upgrade for a service.

We've got a lot of inherit knowledge about this stuff that would be great to 
capture, for example:

* Swift just eats upgrades up - whether you go for every point release, or do 
the N to N+1 jump, provided you read the release notes it's basically always a 
good time with Swift.
* Nova's upgrade_levels is pretty amazing, too. In recent versions you can run 
N+1 apis with a mix of N and N+1 compute nodes - quite convenient.
* Neutron in some configurations dumps all of the flows, you have to watch dhcp 
timeouts, how long services are offline etc, so a few little traps that keep it 
from being perfect.

If we could somehow make this into a tag, that'd be great. Anyone want to have 
a go?


Regards,



Tom
