Hello !

I don't see any doc about system upgrades (minor and major). For minor upgrades (inside LTS, let's say Ubuntu 16.04), is it safe to "apt upgrade" all the hosts and LXC containers ?

To push to the limit, how ar we supposed to upgrade from Ubuntu 16.04 to Ubuntu 18.04 ? Inplace upgrade ? What difference between hosts and LXC containers ? Add new nodes, remove old nodes ? (need nodes !)

If someone manage an OpenStack Cloud with OSA for several years, you certainly have some comments !

Thanks.
