Hi, I am probing how to upgrade SLES7 to SLES8 automaticially. I found there is a "upgrade" mode in AutoYast installation guide. But it seems that it don't work. I checked autoyast source in SLES8 CD and found that autoyast don't parse "upgrade" mode. Who can tell me if autoyast support upgrade installation? If can, what should we do? I also try to use SLES8 CD to upgrade a SLES7 system manually. When enter into "installation setting" window, there are only three options: "New installation","Boot installed system" and "abort installation". But the figure 4.2 in SLES8 installation guide shows that there is another option "Update an existing system". I guessed that SLES8 can not upgrade a SLES7 system, right? Thanks. ____________________________________________________ University of Science and Technology of China (USTC) Alumni Email System - free email service for USTC alumni for life.
