According to http://en.opensuse.org/Updating_SUSE_Linux, "Updating from one version to another is unsupported and may result in system inconsistencies. Performing distribution upgrades in the running system increases the risk of causing damage."

Does that mean that upgrading from 10.0 to 10.1 (a few packages at a time over dialup using YOU) is going to break my system?

Will I be able to resolve all of the dependency conflicts that YAST says will occur every time I think about updating a core package?
