If a million users upgrade and there is a 1% chance of upgrade problems 
you will see 1,000 user posts saying that they can't upgrade.

The probability of upgrade problems will never be 0. I can tell you 
right now that I had problems with my laptop. After I upgraded, Dapper 
wouldn't detect my ethernet card and I had to run modprobe. The best you 
can do is upgrade just one system and after it's been working for 
several days upgrade another.

I did it from the command line. Not only that, but from Ctrl+Alt+F1. And 
I recommend that you do the same. At one point during the upgrade, the 
system might kill X (it happens with me all the time) so you don't want 
to be upgrading from X.

Yes, that's what I was suggesting. But 500-600US is bad :(

You might be better off just not upgrading the server. If this is a 
critical system I too would be afraid of upgrading. I might be willing 
to take a 1-5% chance on my desktop, but not on a critical server.
