Comment 4 for bug 1260129

Edgar, many apologies for my tardiness, but there is not yet an upgrade procedure for Havana -> Icehouse. And this is the only place where that information would be relevant, right?

So have added the upgrade bug: https://bugs.launchpad.net/openstack-manuals/+bug/1307761

neutron isn't currently covered in the Ops Guide procedures for Havana (because it wasn't used in the architecture for the previous version), so I can't just slot it in.

Until that happens, I've added a note here: https://wiki.openstack.org/wiki/ReleaseNotes/Icehouse#General_Upgrade_Notes
Could you please review this? Should anything else be said?
