I'd like to upgrade my 11.0 to 11.1 system using a DVD. During the install, only the openSuse 11.1 repository is used so the package manager says it will remove the software I have from other repositories such as nvidia, packman, vlc.

There is an install screen that shows it is disabling all my 11.0 repositories. I've tried enabling those and changing the location to the 11.1 repositories, but the package manager does not honor those changes. I'd rather not have to uninstall a bunch of packages, then when the system is up, re-add my repositories and re-install the packages that were removed.

So my question is what is the method I should be using to upgrade (from DVD or network) so that I upgrade all my repositories at once?
