a: No need to reboot the server, as long as you have the "alternate" CD
(which I think the server CD is by default) all you need to do is mount the
CD, and then run /media/cdrom/cdromupgrade script as root and using the
full path. It will prompt you about overwriting config files.

Backups. Always make backups.

I just upgraded both my servers at home using the do-release-upgrade
script (they both have Internet access) and I had zero issues.
