Without _any_ downtime?
You can bet there will be a kernel update, so going down is inevitable..
Not only that. Many programs get new configuration files, with the original one moved to a backup (.rpmold). Or the old one is preserved and the new one copied alongside (.rpmnew). In any case, the admin has got to review all those before the system is fully operational after the upgrade. Some services run perfectly the first moment, some others need a lot of reconfiguration.
So, yes, there is downtime.
Please stop suggesting "it is impossible to survive a dist upgrade". Usually you get a mail in every case of .rpmnew or .rpmold, so you can fix if necessary on-the-fly. Next we need the chance to survive during dist upgarade - noone is requesting 100% instantly. SLES/SLED claims to be "Enterprise", haha...
