Hey guys,
I just recently rebuilt the OpenStack infrastructure at my work to upgrade
from Juno to Liberty, before wiping everything clean I made dumps of all
the databases and the instances where persisted though the upgrade via NFS.
Now that I have the infrastructure up and going again I was won
I would expect that if you have the databases in place, and they went through
the proper migrations, that your instances would still be there.
You can check the nova database instances table using the uuid.
How exactly did you 'wipe everything clean'?

Hey Abel,
When I say 'wiped everything clean" I mean that we made backups of the
databases and configuration on all hosts before reinstalling Ubuntu 14.04
LTS on top to start with a clean slate, we did this because we decided to
make the change to the LinuxBridge agent from the OpenVSwitch agent p
Personally, I'd just try to load the instance images like you said. If you
try to load Icehouse records onto Liberty code its not going to work.
Typically you'd do the upgrade one step at a time with database migrations
done at every step.
