Well we updated from kilo to liberty a few weeks ago and i can tell you we had a hard time doing it. Prepare yourself for hours of debugging.

Basically you add liberty repos, stop all services (or by type if in production), upgrade packages, make changes to conf files(not much has changed), resync db and restart services.

You should check link text for some guidance on what services should be updated before others and for conf file modifications!

And as always check on installation docs to see the changes differences from kilo!

ok. so most likely the same as my deployment. just i'm not using DVR as currently we need to have a public IP also for compute to have DVR working rite? and how is the performance?

Yes...You lose a public ip per compute node for fip namespace! But the advantages weight more: no single point of failuire, on bottleneck for internet traffic and interVM traffic. All trffic is done on the compute node that the instance resides to as opposed to legacy neutron where ALL traffic
