Is it possible to zypper up?

I have 2 computers, both running 11.1 rc1, the desktop is running Gnome and my laptop is running KDE. I have the desktop downloading the ISO (since there is no delta :P) but on my laptop (which is far less important machine) I decided to try and “zypper up” since I had heard that you could do that to go from beta 5 to RC1.

When I issued the command, it told me I was downloading eight hundred and some odd megs of files and I noticed there was a lot of yast and x.org packages so I assumed that it would work fine. It has been running all day so I don’t know what will happen, but does anyone know if this will leave me with the GM edition?

After starting it on my laptop I got impatient and tried it on my desktop but it said I would only receive one hundred and something megs and 15 or so packages so I didn’t do it. any ideas?
